Cathy had been watching her brother Adam for a long time. Despite his age of 17, the boy had a muscular, athletic physique. Because he did a lot of sports. Everyone in their family used to wear only one pair of underwear at home. They were used to it. There was no shyness between them. So Cathy could see how her brother was maturing into a man and vice versa. They were not shy in front of each other. As they started to grow up, the boy’s genitals only grew. Even when he was at rest, it was big for her. Cathy’s imagination started. She wanted to see him in a state of excitement. One night, she decided to sneak into her brother’s room and have a little fun with him, if she was in there too. So she did. When their parents went to bed, she pretended to go to bed too. She waited an hour or two and went over to her brother’s room. The boy was lying on the bed and was not covered. A small lamp was on next to her bed, illuminating the bed. When she got closer, she saw that the boy’s cock was resting between his legs. She sat on the edge of the bed and carefully took hold of his cock. Her fingers locked on it and she slowly began to pull the skin on it. At this, the penis slowly began to swell in her hand and soon it was erect. Cathy looked at the huge cock in amazement. She slowly bent over him and first licked the large head and then took the already throbbing penis. Adam kept his eyes closed, but he was already up. He enjoyed the warm and soft lips and the skillfully moving tongue that excited his head. Cathy sucked the huge cock without caring about anything now. Adam placed his hand on the girl’s shapely bottom and reached between her legs. The girl’s pussy was already dripping with moisture.
– What are you doing Cath?? – he asked and put his hand on the girl’s head to stop sucking.
– I wanted you, brother. – he said looking at the boy longingly.
– But you’re my sister, you can’t do this! – the boy said.
– It’s okay, I’ve been watching you for a long time, brother, your cock is nice and I was wondering how big it would be when it’s erect. Nice piece. I want you to fuck me! – Cathy said longingly and didn’t let go of the stiff cock for a moment. The boy didn’t think much.
– But promise not to tell anyone, not even your mother!
– I promise.
– Come, lie on me, I want to lick your pussy! – he gave the order. The girl obeyed with pleasure. They indulged each other in sixty-nine positions. The boy stuck his tongue deep into her vagina. He wasn’t surprised that his sister was no longer a virgin. Cathy let the throbbing penis go all the way down her throat and massaged her balls.
– Ahhh yes, you’re doing it right sister, suck my cock sweetie! Ahhh! – she panted while licking her pussy. – Come, sit in it, I want to feel your pussy! – she said. Cathy turned around and sat on the boy’s thighs and took the huge cock in her hands.
– Beautiful! – She said and started to stroke it a little.
– Ahhhh you’re doing it right, let’s fuck now I want you! – she grabbed the girl’s ass. Who slowly inserted the throbbing tool into herself and slowly sat all the way inside. The boy put both hands on her ass and started to move rhythmically. As the cock went in the wet vagina, his balls clicked on the girl’s shapely ass.
– Ahhhh, ohhhh, ahhh! – They both panted faster and faster.
– Ahhh this fucking feels good hoooooooooooooo ahhhh! – Adam moaned, feeling the climax coming.
– Ahhhhh brother I love it, your huge cock fucks hard and ahhhh! – Cathy panted. The boy’s cock filled her vagina completely, almost penetrating her uterus.
– Ahhh I’m going to go, get off, sister I don’t want to cum inside you! – she tried to push her brother away who was in ecstasy.
– Come inside me, brother shoot your cum inside me ahhh!
– Ahhhhh I’m enjoying ahhhhh! – the boy twitched and his cock shot into her pussy. A lot of cum poured into the girl, so much that it even flowed out of her pussy. Cathy lay on the boy, his cock still throbbing in her pussy.
– That was good brother, aren’t we going to fuck again? – she kissed the boy.
-If you want, you rode fantastically..,- the boy praised. Cathy slowly got off him and stroked his already limp cock.
-I love your cock!
She wished her brother good night and went
