She tried to stop me then but with my mouth sucking her boobs, teeth softly biting her nipples, she couldnt stop me for long. I unbuttoned her jeans a...d start playing with her pussy over her underwear while sucking her boobs. Her underwear was completely wet and she was making loud noises. She put her hand on my dick and started feeling it over my jeans. I removed her jeans and underwear and she did the same to me.She started playing with my dick and i was playing with her pussy. We soon got. Eventually we went to bed. He went to his room and i went to the empty guest room. It was still kinda early so i wasn't that tired, but the booze always makes me horny. So i started playing with myself a bit until i was stiff as a rock. I slowly rub my cock, closing my eyes and letting my imagination wander. All of a sudden i hear the door creak open. I quickly stuff my dick back in my pants and pretend to be asleep. Then i realized it was Derick's sister who had come in, she must have been at. Her body felt so soft and warm in his arms, her skin against his.He slipped one hand down between her legs and she obediently spread them to provide him with better access. He found her pussy already wet with desire and he easily slipped his first two fingers inside of her. She moaned loudly in his ear as his fingers penetrated her cunt. She pressed her body tighter against his and pressed against his questing hand, pushing his fingers deeper inside of her. One of her arms snaked around his. It was a decent sized room, the kind youd have a big family dinner like thanksgiving at. Only the dinner table in this room was a beer pong table. I saw Sarah across the room intensely watching some people play pong. I made my way over to her and said hey and we started talking. We watched the game and she went on about what happened at work that day. Periodically shed cut herself of from telling her own story to let out a "woohoo!" everytime someome made a good shot, then shed continue her.
