Early graduation!

I look at Garrett, Lucas and Seth through the window. They still look clueless. As they should be. I try to weigh the scenarios. They may very well overwhelm me. I'm on birth control, so it's not like even if there is an "accident" I really have anything to worry about. Diseases on the other hand is a legit concern, I don't know who they've slept with. It's risky.

On the other hand, I suspect I'd be in for the ride of my life. I am just on edge enough that the idea of trying on three cocks in one go is seriously turning me on. In the end my sex drive totally clobbers my rational thinking. I take a breath and say, "I'm in."

Perkins looks genuinely surprised, like he didn't expect that. If you had asked me fifteen minutes ago if I would ever do something like this the answer would be no.

I follow him back into the classroom. He explains the rules. Their eyes get huge, they look at me, open-mouthed.

Perkins said, "Now, if it gets too be too much, and Miss Gailliard says she is done, she is done. All lab activities will stop. She can back out at any point and there will be no penalty. It does mean your lab grade will be incomplete and you'll be taking this class again. It also means no retaliation. If I find out there are any acts of retaliaton, I will hunt you down and castrate you."

The three nod their head in understanding. They are dumb, but not that dumb.

Now the awkward part, the part where a foursome between a girl and three guys who don't regularly interact with each other. I figure the easiest thing to get them started is to get them ready, and hopefully by the time they are ready, I'll be ready. I appreciate Perkins reiterating the option to back out, but I don't see it happening.

I take my shirt off and drop it to the floor, then get down on my knees. As one, they all stand up and walk over, standing in front of me in a tight semi-circle. They unzip almost simultaneously. This is super creepy in one way.

They could take some manscaping lessons, but it isn't horrible. It smells like Garrett flew a solo mission recently but it isn't an intolerable smell. I look up at them, looking down at me, still in some weird state of shock. Which makes sense, it isn't every day you go to a tutoring session with two other guys and there is a girl there you all get to fuck.

I take Garrett into my mouth first since he is standing directly in front of me. His cock responds enthusiastically. Then I'm getting smacked on the side of my head with Lucas' cock so I turn my attention to him next. What he makes up for in average length he makes up for in girth. Then it's Seth's turn. Apparently the signal for it's-my-turn in this situation is to slap the girl with your dick. While I'm making Seth's wildest dreams come true, Lucas has knelt down behind me and removes my bra. He and Garrett each pick a breast and start trying to get me warmed up in whatever way they think will do the job. Though with the chill air and my nipples almost painfully hard, it's almost a relief when they start sucking on them. The warmth of their mouths gives me a little relief and combining that with Seth's ten-inch cock, I'm starting to really get into this.

Seth pulls out, and the other stand and help me stand as well. They each present their cock, expecting a hand job. Hey, if I'm going to do this I might as well please them. The faster I do, the faster this is all done. Seth meanwhile moves behind me, loosens my belt, unbuttons and unzips my jeans and pulls them down to my knees. Still behind me, with his massive member pressed against my ass and back, he starts fondling my breasts and tweaking my nipples. It hurts a little but it ius also an electrifying sensation and I moan softly at his touch. Taking that as a good sign, he traces lines down my belly with his hands and they stop in between my thighs.

His hands stroke there a little, but then he moves to the prize. His fingers are like magic through the fabric of my thong and I can feel the warm moisture soaking into it. He slides his hand inside my panties and spreads my labia with his fingers, and then his unused fingers find my clit. I moan louder as he gradually increases pressure and strokes. Then he squeezes it a little and it sends me through the roof.

I bend over to pull my thong down as well as my jeans. Lucas takes advantage of my position and guides his cock into my exposed pussy and penetrates, slamming his cock in deep. He grabs my hips and goes and starts thrusting away. I grab my ankles to brace myself and get a slightly different view. Watching his cock slide back and forth between my labia only turns me on more.

I don't know how long he was in, but Garrett taps him on the shoulder and says "Brace yourself, Riley." I splay my hands out in front of me and Garrett pushes his way in. His rhythm is slower but he definitely fucks harder. I can't help making the noises. Nathan has nothing on these guys.

Seth walks over for his turn. He asks me to stand up. I do, and he grabs my wrists from behind. "Now bend over." He pins my wrists behind me with one hand and guides his cock in with the other. His thrusts are no less vigorous than Garrett, and he slaps my ass with his free hand every once in awhile. I am starting to believe they didn't really need the "educational" aspect of the lab. Though it is apparent their sex education is strongly based in however many hours they have spent watching porn on the internet.

Lucas takes advantage of my compromised position to stand in front of me and push his cock into my mouth. They thrust in sync - when Seth is driving deep behind, Lucas is sliding out. When Seth pulls back, Lucas is pushing in. Then Garrett takes a turn in front. Seth and Lucas trade off behind me, and Lucas gives Garrett a little more time before he taps on Garrett's shoulder and they trade off. Lucas and Seth make it a point to thrust in at the same time which provides a different effect than the back-and-forth effect I was getting.

In a haze of quasi-orgasms and involuntary moans, it occurs to me with all this noise I am making, I don't remember if anyone bothered to lock the door before we started.
