I love being fucked from behind. It hits all the right spots. He started off slowly at first and then got faster and faster. Then he was fucking me VE...RY hard. I was moaning so loud feeling his cock fuck me like that. He put me back on the bed and put my legs over his shoulders. His cock went so deep in my pussy like this. Mmm…. it felt so good being on my back with his cock slamming into my pussy. Being fucked hard and being naughty was so hot. He took some oil off of the table and put it all. One way or another Karl knew things would work out."Actually," Karl said as he decided he needed to get his two cents into the discussion. "I sort of like the idea of Tammy getting pregnant." Then gave her a kiss before she could say anything in protest.Reeve laughed and Darlene gasped. Their reaction seemed to cancel out each others expression. Neither of them could find anything to add or say in rebuttal.During the lull in the conversation caused by Karl's admission and keeping Tammy tongue. I was angry with myself for not lasting longer because I wanted to fuck my sister all night long, but I knew I had two more chances.We had used up the last two condoms within about an hour, and it felt so naughty having to keep quiet while we had sex together with our parents only a few yards away, which made the sex even more dirty and fun. I was still horny so I gave her oral sex, and she was struggling to keep quiet which was such a turn-on, before she returned the favor and after I came in. He wanted to ram his thick shaft of flesh into her wet hole, past those inviting little folds of pink flesh that guarded the moist elastic opening to her vaginal passage. He knew from the way she had looked at him that she wanted him to. She must be crazy to get fucked, he thought to himself, as Lucy told him of Ed's tactics in once again not fucking Sandy. He wondered what Ed could be up to. Ed had always seemed normal enough to him, and he was certainly not one to pass up a good piece of ass.
