I was a littlescared as my ass was now completely exposed.She sensuously peeled off her black silk panties and stuffed them inmy mouth, using some mas...ing tape to keep them in place. I closed myeyes in ecstasy as she fiddled with something near her crotch.As I opened my eyes I was shocked to see a penis jutting out fromher waist. It must be one of those strap-on things I thoughtreflecting on the kinkiness of this youngster."Now then, we get to have sex," she said sadistically. I could seeher. I removed her bra and threw it away.We deep kissed for a long time, it was very passionate and rough. I too took off my clothes, we were now only in our underwears. We lay down on the sofa, with me beside her, I bent down to lick her nipples and pinch them occasionally. I ran my hand over her belly, slowly passing it over the crotch and rubbing it.We continued kissing, our salivas were dripping in each other’s mouths. I kept rubbing my palm over her pussy. Her body was writhing with pleasure,. Whether or not Lisa saw the bulge or not was beyond my knowledge. But if I thought the evening's weirdness was over, I was wrong. I was completely wrong. Five minutes later, I steered the car into the bookstore parking lot. Because there were no parking places near the front door, I was forced to find a spot near the rear of the lot. And that is where the adventure and the unknown continued.I parked my car between two sedans, one which had a gentleman wearing a long trench coat leaning against. You could rub the tip across my face to tease me some before you lift it out of the way so I could mouth and lick your testicles. My hot tongue reaching down under them gives you an idea and you turn around so I can lick and suck your buttocks and tight hole. As my tongue gets inside a bit, you start jerking yourself off slowly.With your penis dribbling out, you decide to really fuck my mouth some more. My cries of passion are almost completely muffled by your cock in my throat, saliva running.
