I lived at home and commuted to college for the first couple of years. One of my girlfriends was also still living with her (very religious) parents, so our opportunities for sex were mostly limited to parking. She had let me know she wasn't ready for intercourse, and I wasn't too keen on trying that in a car, either, so we kept it to kissing, fondling, and oral sex...which she loved both to receive and to give.
"Alicia" would often wear a sweatshirt and sweatpants on dates when we were planning to park... Never going bra-less (her fundamentalist dad would have noticed that at once), but loose clothing was good for what we had in mind.
We'd find a dark residential street and park. On the occasions I received her mouth first, after some preliminary kissing, she would get on her knees in the front passenger seat, lean in and unzip me, then stroke and lick "Sparky" lightly before taking me into her warm mouth.
Alicia was *wonderful* at sliding and rolling her tongue as she moved her lips back and forth. I would pull up her sweatshirt in back, un-clip her bra, move it out of the way, and begin cupping, stroking and fondling her large and beautiful bare breasts inside her sweatshirt, as she continued to fellate me.
As I got closer to a climax, I would move my hands past the waistband of her pants and inside, alternately stroking her bare hips inside her panties and moving my hands to her belly, to stroke her there and then move them to the sides of her pubic mound, coming a little closer to her pussy lips each time, until my fingertips could stroke her wet vulva and slip inside, stroke her labia again and slide up into her crack, then start the cycle all over again... as she continued to suck me sweetly, a little faster, and I began thrusting.
We had a signal... when I was close to coming, I'd tap her on her left butt cheek, and she would quickly take her lips off my cock and grab a towel to take my climax.
But one sweet night, we were both really aroused. I had first given her two very long climaxes with my own lips and tongue, and she was ready for more even as she pulled her pants back into place and got into position to fellate me.
It was a very dark night, and the windows were really fogged up, so we didn't worry much about being seen... She nodded when I asked her about what I wanted to do, and went back to sucking me as I pulled up her shirt to let her breasts spill out and down, fingering her nipples and cupping those sweet tits, then actually pulling her pants back down to her knees, as she continued to suck me, as beautifully as ever and with a new urgency,
It really turned me on to be able to stroke and rub her soft body without her clothes in the way, while she sucked me... And suddenly, a sweet warm explosion pulsed through my genitals and I gasped as I shot jets into her mouth.
Her eyes were wide as she pulled back, and her cheeks were puffed out like a squirrel's. She coughed and spit most of it into the towel, then shook her head at the mess and said something like, "All I could think was, what do I do with it?!?"
I apologized and we scrambled to clean up and get her clothes back in place. She was really worried that her parents would find semen on her shirt, but we didn't see much there, and she ended up sneaking into her home, just in case.
I was embarrassed at having lost control, and felt inhibited for weeks afterward. But we eventually got to where we could laugh about the memory, and Alicia said that if it happened again, she'd try to swallow.
One of the sweetest orgasms I'd ever had up to that point, though...
