Barbara’s breasts weren’t huge, just kinda medium size but were nice and firm, and her nipples were very responsive. When she got excited they’d...get hard and stick out about a half an inch. We would kiss, and I’d fondle her breasts for a few minutes until eventually a gentle hand would start my trip downward. How gentle the push was, was directly related to her arousal. The hotter I’d gotten Barbara, the harder the push. The push would move my mouth to her nipples. There was no doubt from her. ”“So what will you do with yourself now, Jennifer? You can't stay inside hiding from the world all summer.”Lisa spoke up. “Go suck someone's cock. You ought to have the practice.”She continued, “Maybe I'll even let you suck my boyfriend off this weekend. I want to watch him screw you. He'd do it for me if I asked. Hmm, I wonder if Dad will let me watch him do you some time, too?”Jennifer didn't know what to say, so she answered, “Sure, whatever, Lisa.”Their mother laughed and said, “OK, enough,. .." I moaned as I pushed against his finger.He leaned over my back and said, "Do you really want me to?" God... yes... fuck me!!!" I pleaded. "AAAHH UGH! Yeah... !!!" I yelled as he slipped a second finger into me. He pushed them in hard. I heard the slothing sound of my pussy juice as his fingers moved within me. I heard the sound of his zipper and looked over my shoulder to see him reach into his pants. My eyes widened as he pulled out his huge, hard cock. It was bigger than I remembered.. I instantly grew rock hard and began to get nervous because this wasn't rite. She told to to lay on the table and that no one will know of this. As she pulled my shorts down I unclipped her small bra and was surprised to see her little petite tits all hard and erect. She ran to get some Vaseline with her shirt off. I thought to myself is this really happening am I gonna finally fuck her? When she came back she took globs of Vaseline and started jerking my 7 inch cock with it. The Vaseline.
