Despite her best efforts we still had grinding and a bit of up and down movement just from the crowded car and the road. After several minutes Nena was getting tired and her vice grip started to slip for moments and then we would have all kinds of movement. Although small I am sure when you are trying not to move at all even the smallest movements feel huge. In these momentary lapses in grip I would get spikes in pleasure and panic. I was building up again and dancing was going to cum in her again. The second time would be worse because this one would be driven completely by fucking my sister not an accident. It must have been during one of these lapses in my sister's grip when she started getting pleasure too. Although not intended on her part either. She fought with herself to keep from cumming as well. She tried to hold us locked in threeway place as best she could but just could not keep the pressure up long flashing enough to stave off the inevitable. Then we hit the hills. We did not see them coming and honestly we had both forgotten about them with our minds on trying not to cum into each other and all. The first hill when we it hit gave every one in the car a surprise except for the ones blowjob up front who college saw it coming. For Nena and I though it was a whole different experience. Have you ever had butterfly's in your stomach when having sex? Probably not but I will tell you it is amazing and terrifying. That first hill gave us two full length strokes we could not have stopped even if we wanted to. I know this because we did try stopping the strokes. My sister tensed up again and I tried to press my self into the seat. It did not help. It was pure pleasure for both of us although neither of us wanted it. But before that Amy had serviced 7 different guys. I thought of my new cool boyfriend. She strived to remember her human form. “I’m going to help you feel better, just like I did when you cried when you were little.” She leaned over me and placed her hand on the back of my head, guiding me to her breast. "Wow, ultimate control. “Okay I hope you liked that. I snapped around to her, startled, scared, realisation dawning on just where we were and what we were doing. Then again, who would look between someone's crouch? She had been right. "Now that's better." She sucked at my shaft, her pussy eager for my cum college to spill into her. Then sat back down quickly, almost a cannonball back into the water. Her tongue flicked across her pink lips. “Well, I… uh…” Phil started clumsily. “Okay, but only if you try to keep up this time.” I teased him. Darlene's rush to the surface forced Deana back from the side of the pool. After a few minutes he got real naughty and pulled it out of his threeway suit and just about gave me a heart attack. My twat spread wider and wider, stretching to accommodate his huge dick. They test us every two weeks. Her large breasts rose and fell as her golden eyes swept up and down my blowjob body. Josh ended the call and he called Karen and flashing told her what Susan told him. And before he could find a towel to cover dancing himself, I saw his juicy dick. I chuckled as I ran a finger down her face and over her chin.
