Last term Patsy traded blow jobs for help with her homework. This term her best friend needs help to improve her grades too.
I was never a morning person and I was only half awake when I poured myself a cup of coffee and sat down to eat a slice of toast.
I has just taken my first bite when my simple breakfast was snatched from my hand by my spritely sister.
“Bet you can’t catch me!” She teased, wide awake and scampering out of the room.
I gave chase as she headed towards the stairs and made a grab for her ankle as she reached the fifth flight.
She stumbled and fell.
I pinned her down.
The game was on.
I rolled her onto her back.
“No.
Not here.” She protested.
“I could fall down the stairs.”
“You’ll be fine.
Hold on tight.”
I pulled up her pretty pink baby doll nightie to reveal her bare teenage pussy.
My cock was already hard and primed inside my pyjamas and my sister was already wet and willing.
Neither of us needed foreplay. It was only a moment before Patsy was clinging onto the stair rail with all her might as my cock drove its way up her fanny. Filling her fully. Throbbing and twitching and squirming and squirting within in her. Shooting my incestuous spunk safely into the custody of a trusty condom.
———————————–
It wasn’t the first time we’d fucked.
We’d been at it regularly since Patsy had asked me to help her improve her grades in French so that mum and dad would let her go on the school trip to Paris.
She had agreed to pay me with blowjobs but, things had progressed since then and she’d recently asked me to help with her Spanish lessons in return for full on sex.
In theory, this morning’s shag on the stairs was just the latest payment for my services, but we both knew that our relationship had grown beyond a simple “sex for studies” deal.
We wanted each other.
We needed each other.
Our secret sibling sexcapades had because the most exciting part of our lives.
————————————
I lifted her hot, sweaty, sated body off the stairs and carried her up to her bed, where we lay, cuddling and caressing in the afterglow of our intimacy.
“That was a good one,” she smiled with a kiss.
“I’d never thought about doing it on the stairs.”
“Well, I’ve screwed you in every room of the house – I’m running out of ideas.
I might have to do you in the garden next!”
“Hmmm, in the shed perhaps… or on the swing.” she suggested.
That made me laugh, but I was still a nerd by nature, and I wasn’t too distracted to forget about her lessons.
“We’d better keep up your studies first though.
We need to work on your Spanish, if you want to be on that trip to the Costa Del Sol.”
“I suppose so,” she sighed, stroking my cock.
“You know,” she continued, “Beverley has noticed that my grades have got much better lately and she kinda guessed that you might be helping me.”
“Yes..? Guessed what?”
I wondered if my sister might have shared our sexy secrets with her best friend.
“Oh don’t worry, she doesn’t know about… you know… us.
I haven’t said “anything”. She just wondered how you’d feel about tutoring her too.”
“Well,”
I decided to play it straight.
“Private tutors cost £50 an hour but you could tell Beverley I’ll help her for £30.”
“Okay, that sounds fair, but, er, what if she wants to pay in another way – like me?”
“I thought you said you’d kept that a secret.”
“Well, yeah, of course. I haven’t told her anything yet, but… “She gave me another cuddle “…well she is my best friend and her parents might not let her go to Spain unless she gets some decent grades.”
“I’ve heard that one before!” I told her. “You can’t expect me to fall for it again.”
“I know, but I wouldn’t want her to miss out on the trip.
And she’s 15, but I don’t think she’s ever been with a boy – I mean, she says she’s done some stuff with one of her cousins but I think that’s just bullshit.”
I had to take a moment to think.
I hadn’t even been considering other girls.
Patsy was enough for me.
But Beverley was attractive too – in her own way.
I wondered whether my sister had really thought this through though.
“Are you saying I should have sex with her?
How would you feel about that?
I thought you girls didn’t like to share your boyfriends and, besides we’re going to run out of condoms soon.”
“No, don’t be silly!” she gave me a playful slap.
“Not sex,” she seemed a little embarrassed.
“I don’t want you screwing anyone else.
I was just thinking she could pay you with blowjobs or something, like I used to.”
“Well, if you’re sure,” I conceded, “but we both know where that led”.
I slipped under the covers, putting my face between her thighs to eat her out.
“Oh yes!” she squealed.
Her Spanish lesson was going to have to wait…
————————————-
The following Friday;
“Do you think you can handle us both?”
“What?”
“I’ve invited Bev for a sleepover, so you can help us both with our Spansh homework.”
“Hiya!”
Beverley appeared behind my sister, before I could say another word. Patsy had given me no choice.
“Oh, hi.” It was probably the first time I’d ever spoken to Beverley. I’d always been too busy attending to my own studies whenever she’d called round, but tonight I’d be helping with hers instead.
We waited until mum and dad went to the pub (to celebrate the end of the working week), as usual, then we converted the dining room into a makeshift classroom.
The girls were both still in their school uniforms, just like a real lesson and the TV was turned off, along with all their devices so there was nothing to distract them.
Everything was ready.
I just had to agree the terms of my arrangement with my new student.
“Well Beverley, I suppose that Pat has told you that I’ve been helping her with her homework.”
“Yes,” she grinned and giggled.
“And you’d like me to help you too?”
She gave an embarrassed nod.
“Well, personal tuition doesn’t come cheap but…”
“I know,” she interrupted me excitedly, “and I don’t expect you to help me for free – I thought I might be able to pay you like Patsy does.”
“And how might that be?” I asked in a serious tone. It seemed that Patsy had shared the details of our secret deal.
“Oh, well, er she told me that she needed your help to improve her French last term – so she could get on the Paris trip and you told her she’d have to suck your dick…” There was more nervous laughter.
“Well that’s not quite right, is it Patsy?”
I gave her a stern look.
“I never made her do anything.
She did ask for my help and she couldn’t pay me with money so she offered to do something for me and she agreed that she’d pay me with blowjobs, if I could improve her grades.”
My sister confirmed my version of events.
“So,” I asked Beverley, “Is that what you want to do too?”
“Yes.”
She nodded determinedly… and then bit her lip, pensively.
“Well, er… I think so, but I’ve never done it before… er.
I’m not sure really…”
“I’ll tell you what,” Patsy interrupted.
She had an idea.
“Why don’t you give us both a lesson now and Beverley can watch me “pay” you for mine before we go to bed.”
“Okay?”
“And then she can decide whether or not she wants to “pay” you like that in the morning.”
“And what if I don’t want to?” Bev asked.
“Then I’ll do it instead,” Patsy replied in a matter of fact fashion.
She had it all worked out.
They’d both get a lesson.
Her friend wouldn’t have to suck me off unless she wanted to, but I was going to get two blowjobs anyway.
It was a deal!
—————————————————–
The lesson wasn’t as straightforward as I’d expected.
Both girls were easily distracted and it took a while for us to find any focus or direction.
And once we did start to make progress, I had to slow down to ensure that I was moving at a pace that didn’t leave either of them behind.
So it all took a little longer than usual but, we eventually got through all the work and Patsy and Beverley wrote everything up in their school books, ready to present to their teacher.
We only had about an hour to spare before mum and dad would be coming back home, so we we just had time for a quick bite of supper before the girls went up to bed.
Patsy gave me a wink and asked me to join them in five minutes.
She was ready for me when I arrived at her room.
Standing by her bed, still in her school uniform, while her friend sat on a chair, watching proceedings.
I sat on the mattress, inviting my sister to take the lead.
She undressed in front of me, as she had so many times before and, as ever, I took delight in watching her disrobe.
My cock grew harder and thicker as each layer of clothing hit the floor.
It was a great show, but something was missing…
She was as beautiful as ever.
Her lovely tits.
Her shapely bottom.
Her shameless pussy.
Every inch of her body was as sexy and alluring as ever, but there was something strangely mechanical about my sister’s movements.
They had all the “strip” that I had come to expect, but lacked some of the “tease” that I loved.
I guessed that Patsy was conscious of her friend’s presence and it was effecting her performance.
I hoped it didn’t effect mine!
Fortunately, by the time she had completed her show and the last vestige of her feminine clothing had hit the floor. I knew that I had nothing to worry about.
The sight of the naked teenage girl dropping to her knees before me and unleashing my cock, was just as irresistible as ever.
She went straight to work, without a second of delay.
Gobbling the thick, hard staff with gusto and gorging upon it like a girl who’d been gagging for it since breakfast.
She devoured my dick with a desperate, unadulterated desire.
She no longer seemed to care that her friend was watching her every move.
Maybe she had forgotten that she was even there.
But Beverley was definately still there and she was watching with rapt attention.
She said little, but I had heard her gasp when Patsy pulled off her panties.
She had gone wide eyed when she had seen my swollen cock.
And she had looked away in disbelief when my sturdy member had disappeared into my sister’s mouth.
She watched on in fascination, as Patsy continued to perform her womanly duties with all the skills that she had learned during her regular trips between my thighs.
Slathering and swirling and sucking me to satisfaction before swallowing my salty solution without spilling a single drop.
Pasty serviced me with so much confidence, that her salacious sibling submission looked as natural and normal as breathing, but Bev stared in awe and wonder – and you couldn’t blame her.
Not only was she witnessing felatio for the first time – her best friend was giving it to her big brother!
She was shocked by the taboo, but Patsy and I acted as though it was all routine.
“Very good.” I congratulated her, as she licked my bell end clean and tucked my cock back into my pants.
“My pleasure, Sir,” she replied simply.
“Thank you for my lesson.”
I retired to my bedroom, without further ado
Fully satisfied and planning to attend to my own studies.
I began to read a couple of chapters of analysis on the Russian revolution, but was soon distracted by the girlie chatter from my sister’s room.
There were giggles and gasps and squeals and even slaps and swears.
I suppose it all fairly normal for a teenage sleepover, but I was sure that it was even saucier than usual as they were reflecting on the evening’s events and discussing their plans for morning.
Who knew what they had in mind.
——————————————————
Our parents always let us lie in at the weekend, so we were still in our beds when they shouted up the stairs to tell us that they were going into town to do their weekly shop.
It was only a few minutes later when the girls giggled their way into my bedroom.
“We’re here to pay for Beverley’s lesson, sir.” Patsy chuckled. “Are you ready for us?”
“Of course,” I answered with a smile as my sister placed a towel on the floor beside my bed.
“Is that for me to kneel on?” Beverley asked.
“That’s right,” my sister replied, “but you need to take your nightie off first.”
Her friend stepped forward and then froze, “No… I’m sorry. I can’t.”
She took a step back, embarrassed.
Patsy took her by the hand.
“It’s okay,” she said softly, “I told you I’d do it if you didn’t want to.
It’s no problem.
It’s not like I haven’t sucked it before.” she joked to lighten the mood.
“Oh no, it’s not that. I’m a big girl and I knew what I was getting myself into.
I don’t mind paying my debts, but I er, well… I just don’t want to take my clothes off. I’ve never let a boy see me before. You know… not like that.”
“Oh there’s no need to be embarrassed. I’ll take my nightie off too, if it makes you feel more comfortable. ” Patsy pulled hers over her head and stood naked and unashamed.
“That’s very thoughtful of you, but it just makes things worse.”
Neither Patsy, nor I understood what she meant, so she continued.
“The thing is… well you’re beautiful, aren’t you? Youv’e got a great figure. Any boy would be delighted to see you naked, but no one wants to see me.”
“Who’s told you that?” I asked.
“Well no one’s, actually said it, but none of the boys at school have even tried to kiss me let alone do anything else. I’m just not, er…
What’s the word.
Desirable.”
“Well, that’s because they’ve never seen you in that nightie have they?”
“What do you mean?”
“I mean you usually wear loose trousers and unflaterring jumpers as though you don’t want to be seen.
But in that nightie… well, I’ve got to tell you – it doesn’t leave much to the imagination.
It shows off every curve and you’ve got a lovely figure, if you just dare to show it off.”
“Do you really think so?”
“Look,” I pushed my bedsheet down until she could see the bulge in my boxer shorts.
“Can’t you tell?” I grinned.
“You’re very “desirable”.”
“Oh, er.” She smiled awkwardly.
“Just take it off, please.”
“It’s for the best,” Patsy assured assured her, you don’t want to get his stuff all over it. Your mum’s bound to see it when she does the washing.”
“Ok.” Beverley took a big breath and pulled it off, self consciously and fighting the urge to cover her chest with her arms.
“They really are lovely.” I told her as I stared at her tits and indeed they were.
They were a little bigger than my sister’s, and actually, Beverley was a little bit bigger than Patsy all over.
Some boys would say she was fat (and that was probably why she thought she was unattractive) but in fact she wasn’t much larger than the average girl her age.
And I really didn’t mind.
As far as I was concerned any extra weight just added an extra inch of bounce to her bum and her boobs.
“You need to take your knickers off too.” Patsy whispered.
“Really?
Do I have to?
I’m not likely to get any stuff on them am I?”
I thought she had a good point but Patsy insisted, she’d always been fully naked when she’d sucked me off and she thought Beverley should be too.
“It’s only fair,” she argued, “he’s going to get his pants off, so you should do the same.”
“Yes but…”
“It’s okay,” I suggested a compromise. “Kneel down first and then just slip them off.
I won’t be able to see too much from this angle.”
Beverley nodded in acquiescence and did as I asked. Taking her position, then peeling away her panties and handing them to me as an unexpected gift.
Then she pursed her lips and reached out bravely to grasp my underwear and pull it away, releasing my cock which sprang free to salute her.
She gave a squeal, then looked at it quizzically.
“Could I… er would it be okay if I touched it?”
“Of course.”
“Ooh, feels warm… and stiff, oh… like a big fat sausage.”
I chuckled, “Well just remember not to chew it.”
“No,” Beverley laughed too, “I’ll try not to bite.”
“No,” Patsy offered her advice, “you need to open your mouth as wide as you can.”
Her friend didn’t need any further encouragement, she moved her head forward to consume my cock.
The sensation of her hot breath and her tight lips upon my length was irresistible.
I gasped and closed my eyes, surrendering myself to the novice cocksucker’s skills.
Patsy continued to guide her friend’s first foray into felatio and Beverley served me well.
Tongue teasing.
Lips wanking.
Mouth sucking.
Cock throbbing.
Balls churning.
And then…
She hit the vinegar stroke.
It hadn’t taken very long but the result was explosive!
A canonade of spunk shooting uncontrollably into Beverley’s mouth and throat.
Her response was inevitable and she recoiled in shock, releasing my dick and leaving it free to spray her face and tits with my semen, making her body look like a Jackson Pollock painting.
“Ohmygod. I’m sorry, I’m so sorry.” Beverley apologised. “I was supposed to swallow it wasn’t I?”
“It’s okay.” I assured her.
“It’s your first time.
There’s no shame in getting splattered.
That’s why Patsy told you to take your nightie off, isn’t it?”
“But it’s still polite to swallow.” Patsy insisted. “Here,” she used her fingers to scoop my cream from Beverley’s breast and offered it up for her to eat.
She licked it off hesitantly – out of duty rather than enthusiasm, but reported that it tasted “okay”, and licked more of it from her lips.
She looked at me a little nervously.
“Was that okay sir. I mean. I know it didn’t last very long and I pulled my mouth away and it wasn’t as good as when Patsy did it, but I did my best sir.
You did like it didn’t you?”
“Very much Beverley,” I smiled.
“Good.”
She stood to leave, then remembered what Patsy had taught her to say.
“Oh, er thank you for my lesson sir. I hope to have another one soon.”
She stood up, forgetting to hide her pussy from my sight and then accidentally gave me a view of her bare bum as my sister led her out of my room, leaving their clothes behind them.
They went to the shower with a chorus of girlie giggles and dirty laughs.
I could hear them as they washed together, no doubt stroking and soaping eachother’s naked bodies.
I could picture the scene and longed to join them, but it was only Beverley’s first lesson and we had many more steps to take before I completed her education.
————————————————-
I remained in my bed, listening to the girls and choosing not to disturb them as they dressed and went down to breakfast.
It was shortly after their morning repast when Beverley shouted her “goodbyes” up the stairs and skipped down the path to meet her father.
She barely had time to reach his car before my sister burst into my room.
“Thank God for that.
I thought she’d never leave!”
She pulled off her knickers and bent over my desk – not caring that about the precious study notes that she sent tumbling to the floor.
“We haven’t got long before mum & dad get back, so you’ll have to do me doggy.”
She turned to look at me.
“Come on, hurry up.”
“Okay give me minute,” I retorted as I as eased a condom over my bulging bell end.
“Right.”
I pulled her skirt up and stroked her smooth round buttocks, steering my fingers tantalisingly towards her twat.
“No.
There’s no time for foreplay
Just do me.
I’m ready.
Good and hard.”
So I gave her what she’d asked for.
Driving my cock into her cunt with all my might.
Pounding at her pussy.
Shunting her across my desk.
Rutting away at her like an animal, taking my pleasure, without a thought for her own needs.
I fucked with her urgently, balls deep and anxious to reach my climax without delay.
And Patsy acted as my co conspirator, pushing back, grinding and compressing my cock with her cunny muscles.
There was no thought of edging or teasing.
I came in a passionate hectic haze and Patsy shivered and squirmed as she achieved her own primal peak.
I slumped on top of her freshly fucked body for a moment while we regained our breath.
“Ooh, well that felt nasty.” she whispered.
“I’m sorry, I thought…
“Oh don’t apologise,” she kissed me, “that was exactly what I wanted.
I hope you liked it too.
Especially now I’ve got some competition.”
“You haven’t got any competition…”
“Oh, I think I have.
I think Beverley fancies you,” she chuckled, “I hope you can keep up with us both.”
“Well,” I rolled her onto her back and returned her kiss, “it was a pleasure to have have two naked girls in my room this morning, but there’s only one true “brotherfucker”. “
I pushed a hand under her shirt to grab a tit.
“Are you sure we haven’t got time to do it again?”
