Johnny of course

"Get me a bottle of beer," Johnny orders one of the others, and twists off the top. "Now for some lube," he says, and drizzles a bit over my butthole, making me yelp.

"That's cold!" I protest, which makes Johnny chuckle.

"Good, if it's cold I won't cum as fast."

"That's... good..." I say reluctantly. It is good, isn't it? The thought is jolted from my mind by the feel of something cold and hard at my rear entrance. It's not his cock but it takes a moment for me to realize it's the lip of the bottle.

"Wait... Aren't you going to..."

"You know, we might have to gag her if she keeps this up," he says casually. The thought's enough to make me snap my own mouth shut. "Good girl," he says, patting my butt like I was a good dog.

The hard rim of the bottle presses against my virgin backdoor, and I bite back a groan. I can't help but wonder why he isn't using his fingers, but maybe he just doesn't want to get them dirty.

"Listen to those groans," one of the guys says, "She likes it!"

If I didn't want to prove that I could keep quiet and wasn't chicken I'd correct the guys, but when I don't they all start to talk about it.

".... anal whore.... butt slut...." they're saying, and I pant as more of the bottle forces its way into me.

A yelp nearly escapes me as the bottle tilts, and the coldness reaches my insides.

"Enough lube for now. A girl like you doesn't need much I'm betting," he says, confusing me. What does he mean by 'a girl like me'?

I stop thinking about that when I feel the real thing pressing against my anus. My Johnny's cock presses mercilessly against my poop-shute, making me bite my lips. Instinctively I try to relax like I'm on the toilet, hoping it'll help.

In a way it does. Johnny's cock no longer strains for entry, but slides in, pushing the walls of my butt aside like a bully pushing around nerds.

"Damn, she IS an anal pro. Look at how easily that went in," they say, and I feel the shame deep inside. I just wanted to make it easier on myself, not make myself look easy or slutty. Why do they keep misunderstanding?

"I bet she's loving it. Probably has a real warm feeling deep inside. And that sense of fullness... I bet it's the best thing she's felt all day."

Johnny's words make me redden, but with my face down none of them see it, just my trembling butt. The weird thing is I do feel kind of warm down there, and my crotch does feel all tingly. Full, definitely.

He starts moving quicker, the muscles of my ass too tired to resist, feeling painfully stretched, like when you stretch farther than your muscle can go and stretch the ligaments instead.

An 'oh!' escapes my lips when he pulls out a bit and slams foward again, and the guys laugh, making comments again.

The slap of a hand on my buttock brings another 'oh!' and Johnny's hands smack my cheeks, one after another. The stinging blows distract me from the pain in my rear, and his cock digs deeper and deeper, moves faster and faster.

My body rocks from the blows and thrusts, the strange warmth spreading, the tingling becoming a solid zing of excitement. With horror I realize that my crotch thinks I'm enjoying this.

The thought makes me start saying, "no no no...", but not before Johnny says, "I think I'm gonna cum!"

"Holy fuck, you won the bet!" the guys say, laughing. They laugh even louder when I try to protest, saying "no" again and again as he starts to pound into me with wild abandon.

Johnny's going wild with the spanking and the fucking and his big balls are smacking against my throbbing sex, the hairs tickling my lips. I try to convince myself that they're reaching my clit, that the good feelings I feel escalating are because my pussy's being stimulated somehow, but all of a sudden I'm convulsing, overcome by a surprising wave of pleasure that I realize is an orgasm.

"Oh God!" I exclaim, in pleasure and confusion. I'd just come from a cock in my ass.

I'd just lost the bet!
