Cait and I have dated since sophomore year of college. We both went to a large state university and met in a class we had together freshman year. I had been told stories about Cait that year from her roommate, some harder to believe than others, but they all pointed to the fact she was hyper sexual. I definitely found this out for myself once we started dating. She had an insatiable appetite for sex, jumping at every chance we had to fuck. As a horny college student I obviously had no complaints and was always open to trying new things. One thing in particular she really liked to do was give me blowjobs in random places. The first time she did it we were shopping at the mall when she pulled me into a dressing room and sucked me off right there. I was shocked at first, hearing people only a thin wall away as my girlfriend was on her knees sucking my cock, but when I came harder than I'd ever cum before I knew it was something I could get used to. Our antics grew more and more risky, her sucking me off in parking lots and in the bathroom at parties. A few times we'd get close to being caught by someone but Cait never flinched. She'd always just keep blowing me even when I told her to stop if I heard someone approaching.
The first time we got caught though changed things forever. We had gone to a party a little off campus and were walking back to the dorm building we both lived in. Cait and I had been drinking, which makes her extra horny and less cautious...
"Come on baby! I really want to feel your hard cock in my mouth," she teased me.
We were crossing through a courtyard near our building. It must have been 1-2 AM so the area was light only by the street lights overhead.
"Not here babe, let's just wait till we get back to my room."
"Oh come on, let's have some fun!" She said. "Here, I know the perfect spot."
She grabbed my hand and pulled me off the path a little towards the building. We walked around to what looked like a side entrance with a few stairs where she sat me down and started to undo my pants. I was drunk enough where I didn't care that we weren't really that hidden but I didn't think anyone else would be walking over there at that time of night.
She got my pants open and my underwear out of the way enough to pull my semi-hard cock out. She immediately went down on it, taking it in her mouth and working to make it hard. It didn't take long till I was fully erect with my hand on her head bobbing it up and down.
She was working the shaft with one hand while the other found its way to her pussy underneath her skirt. I leaned forward, lifted her shirt up and her tits fell out into the night air. She never wore a bra, for her comfort and my pleasure, and her massive tits were very impressive for a girl her size. I grabbed one fully in my hand while playing with her nipple in the other. She let out some soft moans, vibrating my cock in her mouth as she did. She looked up at me and popped my cock out of her mouth.
"You like this," she said licking the head of my dick. "You like your girlfriend sucking your cock in public like this?"
Plunging back down, she took as much of it as she could before gagging.
"You're so hard! I bet you like this, your girlfriend exposed and sucking on your cock," she teased. "I feel like such a slut right now."
Here she was, outside with her tits and pussy on display, sucking my cock on her knees. I knew what she wanted so I put my hand back on her head and forced her back down. She continued to work her magic for a couple minutes before I told her to hang on a second...
Off in the distance, the way we had just walked from, I thought I heard voices. I asked her to stop but of course she never so much as slowed down. After a few seconds I was sure that it was voices, sounding like two drunk guys walking this way.
"I know man it was sick!" one voice said. "There were soo many girls there!"
"Yeah but you didn't do anything with any of them," said the other. "You got wasted in like 5 minutes!"
"Haha, yeah well I'm not gonna to turn down free shots!"
They were getting closer and closer. I tried to lift Cait off my cock but she just looked up at me with a mischievous smile and kept at it.
"Dude I'm not gonna make it," one of them said.
"You gonna puke?"
"Haha nah man, already took care of that. I gotta piss like real bad," he responded.
"We're right here, just hold it till we get up to the room!"
"Won't make it!" he responded. "I'll meet you up there!"
