A very sexual transaction had just occurred in the last few moments and I was present, without realizing just how simple it could be.'Would you show y...our's if I paid you'?I thought carefully, as I was about to say just how I felt, horny as fuck, but I refrained, and looked back at him with a coy expression.'Did it have the desired reaction'?He looked down at his crotch, where my eyes were looking, then traced his outline with his fingers, along the shaft, a good eight inches of solid pleasure. She would work her hips up and down, pause and then do it again. All the while biting her lower lip. I had never seen my sister have an orgasm before so I could only guess that was what was happening. She had stopped sucking David Meyer's cock. He stood there with his hard dick inches from her face. His hand was slowly stroking his cock. I could see the bead of clear precum at the head.My dad continued to thrust his cock into Marie. His balls tightened up to the base of his dick. His head was. I felt like I was in tit heaven. I managed to capture her delicious nipples into my mouth and sucked them as hard as I could. I practically inhaled a good amount of her tit meat as well between my lips."AHHHHH! OHHHH! ARRGGG!" Cried Christy, wrapping her arms around my neck and now pushing herself against my body.Our pelvises were smacking together and our thighs quivered with impact. I had most of my huge dick, stuff between her drenching pussy. I could feel her juices continuing to leak out. "Now my turn to teach my little babysitter how real men do it."He slipped his massive hand under my back and easily released the clasp on the top that had almost been his wife's. My breasts and erect nipples sprang into view but were immediately covered by either his eager mouth or nimble fingers. He suckled and twisted, building up the tension down in my dripping pussy. I couldn't help but let out my girly moans of delight. This was nothing like the boys I'd been with at school. After fondling.
