She offers me sex

"Lucy, what are you doing?!"

"Do you know what Susan said to me when I met her?" she said as she took off the rest of her clothes.

"Um, no."

"She said that I was no threat to her because she could tell I was too boring to make a move on you. And she was right! I never would have tried anything with you. Not just because I valued our friendship but because I never tried anything with anyone!" Suddenly, she straddled me, grabbed my hands, and put them on her tits. "John, I'm 21 and I've never dated anyone. Never had anyone touch me like this. Never been kissed. Do you know why?"

"Um, no." I was paralyzed by conflicting emotions. On the one hand, my body was reacting to the naked girl in my lap. My cock knew the only thing separating it from Lucy's apparently virgin pussy was a layer of denim and...whatever my boxers were made of. Either way, it was hard and wanted out. On the other hand, I was worried that my best friend had lost her mind.

"My older sister Tiffany got pregnant when she was in high school. Father sent her away. I was only 10 and I never saw her again. So growing up, I had to be the good girl and make father proud. I had boys ask me out in high school and here. But I always turned them down. I always did the 'right thing' so that I'd be my father's good girl. But not anymore!" Then, she sighed and seemed to calm down a bit. "Look John, you probably think I've lost it. While this is way more impulsive than I usually am, I haven't gone crazy. Think of this as a unique opportunity."

"What do you mean an opportunity?"

"You just found out your girlfriend was cheating on you and she dumped you. What better way to get back at her than to have sex with someone else? And instead of going out trying to pick up some random slut, I'm right here naked in your lap determined to lose my virginity tonight. I could most likely go on campus and easily find someone willing to fuck me but I'd much rather it be you than some random guy at a frat party. So yeah, I'm going to make a bad decision tonight. Either I lose my virginity to my best friend or I find a frat party and announce that I need to get fucked."

I thought about the things that could happen to her if she did that. Her first time would end up a gangbang whether she wanted it or not.

"So, are you going to take this opportunity?" Then, she looked down on me with a smirk. "Or was Susan right about you after all?"

With that, the concern and confusion I was feeling all turned to anger. That was a fresh wound and she definitely touched a nerve. "So, you'd actually go to some frat and let them use you like a slut?"

"Well, yeah. Yes. Yes, I would."

"If you're so determined to be used like a slut, then you might as well be my slut for tonight!" I shoved her off of me and stood up.

"Hey!" she cried out as she landed on the floor. "You didn't have to--" Then, I dropped my pants and shorts revealing to her my hard, 10-inch cock. Her eyes grew wide with shock and awe. "John, I-I had no idea you were this...BIG! I didn't think they got this big for--MMPH!"
