Heather needs to slow down.

The group of nerds thank me as they zipped their pants up, and left the library. Danny was especially grateful, and asked if I would do this again sometime. I was so exhausted and horny I just said 'Yes please'. After laying there on the floor sweaty and stinking of cum I recovered enough to get up and put my clothes back on. The realization of what I did was finally hitting me. I poked my head out the door to make sure no one was around, then I rushed to the nearest bathroom.

I washed the sticky cum off my face, hoping that would be enough for no one to notice. I stared into the mirror at the still unfamiliar face looking back at me. With this new body, and how the potion has been making me behave, I've barely felt like myself lately. But I wouldn't trade this for anything, I was loving every moment of it. Just then someone came into the bathroom, and I tried to look natural, then I saw who it was.

"Heather! You've been getting around lately haven't you?" Gabriel stepped into the bathroom with a smug look on his face.

"Gabriel... what are you-"

"I heard a rumor you serviced a bunch of guys."

"What! How did... that just happened a minute ago!"

"I have my sources. Never mind about that, I need to tell you about another side-effect of the potion."

"There's another side-effect!? Why didn't you tell me about it before."

"Well I didn't think you'd be such a slut!" Gabriel laughed. "See, if you give the potion a lot more semen than it needs, it will use it for other purposes."

"Like what?"

"Well, it will start by making pheromones, and believe me the pheromones it creates are very strong. It won't make a guy do anything he wouldn't normally, but most men won't be able to resist fucking your brains out."

"So... I'm irresistible to guys right now? Why aren't you... you know, fucking me?"

"It doesn't affect me, lucky for you. You should probably avoid any guys for at least a day or two, unless you want them I guess."

"Okay. Is there anything else?"

"Yeah, if there's more than enough semen to make pheromones the potion will use the rest to transform your body further. It's different for each girl, but usually makes you look even sexier. You know, tighter ass, silkier hair, luscious lips, etc."

"That sounds... really good. Are you sure these are side-effects?"

Gabriel laughed at my response. "Well I guess I can see that, sure. But if you give the potion even more cum than that, well something else will happen. I can't tell you what that is, but just lay off the man-juice for a little bit okay?"

"Fine. How long until the pheromones wear off?"

"Well if the rumor is true than you sucked off what, eight guys? So I'd wager two days, so Saturday, but make sure you get another load before Saturday around 10 PM or the whole transformation will wear off."

Luckily I could just fake a sick day tomorrow since it was Friday, that way I could avoid any guys at school. The only other guy I'm ever around is my brother, so I can just stay in my room until the pheromone wears off. However there was still a few classes left in the day, but my grades are fine so I think I'd rather miss a few classes than have a classroom of guys fuck me! Or would I?
