And we both had our shorts and boxers down to our ankles and were jerking off each other's rock hard dicks before I drove us to the next block. We did...that the entire time, as other cars drove past us in the other direction, and as we passed c***dren and adults walking or just doing nothing outside. I even waved hello to a friend's father with Josh jerking me off and me doing the same to him as he waved hello back to me. I told Josh that doing this was just fine if we couldn't find a safe place. She was planting wet kisses on the lips, my neck, my nipples and was partially lying on top of me. As she started going down towards my stomach and for the first time touched my raging hardness, I realized to my horror that I have not had sex for a fairly long time and I won’t last long. I had to do something immediately. I quickly changed position and made her lie down on her back and started kissing her all over. I was fascinated by her perky breasts and flat stomach and licked her all over. ” i had increased my speed and my dick was moving in rhythm like a piston moving in and out of engine, as my balls slapped aganist her body and her thighs collided with mine, strange sounds emanated and filled the room..My sis was now at her peak and enjoying completely uttering mouthful of curses like” ffffucck meeee harderrr,u bastard..Ttteaarr my cuunt,ahhhhh ohhhh hhmmmmmmm ahhhhhhhhh, you son of bitch give it to me hardder hmmmmm yyesssss llike that,, u asshole,, fffffffffffuccckkk. While I continued to bathe his cock he grabbed my nipple and began to pinch and pull. The other set of hands had made their way back to my pussy and were idly stroking the smooth lips occasionally pausing to flick my clit in their progress. Pausing to enjoy the sensation of having four hands on me I pulled of the cock in my mouth, I said "Umm... That's nice" and went back to noisily sucking and licking the beautiful cock in front of me. The finger that had been stroking my nether lips slipped.
