Then his hand went inside my bikini bottoms as he began fingering me.I can't explain it, but I just closed my eyes and let him finger me over and over... reveling in my orgasms. What I never stopped to think about was that I was in a fifteen passenger van, and I was the sixteenth person. I was so aroused, it never occurred to me that my breasts were fully exposed by then and that everyone else in the van knew what was going on. Aside from the driver, there were nine other guys and five other. Then I worked my way down the front of her shoulder,across her chest.Now both her hands were on my head and she was breathing a little faster.I started up her other shoulder pulling the strap down then kissing back down trying to get the top of her dress down so I could get to her tits."Stop" she said."Unzip it in back so you don't rip it." I unzipped the dress and pulled the straps down her arms and she pulled her arms out.She was wearing a fancy black bra.I didn't waste any time unsnapping. Pat's hands started wandering more enthusiastically over my body, and she started making even more appreciative comments. Lily (I guessed) judged the moment right to say, "Me close. Mark finish me then your turn. You undress now."Pat hesitated, but only briefly, then said, "Okay." She wasn't exactly enthusiastic, but it'd still result in another naked girl - and easily the better looking of the two - so I wasn't going to complain. In fact, I was going to watch.Turning to me, Lily said, "Faster. Nothing mattered anymore, not the exam, not Aman, not the invigilator.I was just enjoying that awesome fingering. I was literally wincing, biting my lip. My head was up with my eyes closed. My legs were closing on their own due to the sheer pleasure. I was aware of where I was, but no cell in me was allowing me to stop.I felt like someone was calling me from a long-distance away. But I gave it no heed. Now my hips were moving to the rhythm of my fingers in circles – a traditional Sindhi girl.
