It's too late

Any strength that you might have had fled from your body the minute your friend rammed his cock into you. "No, Mathew, please, stop!" You begged him, but he refused. He pulled back until just the tip of his cock was inside your ass, then slammed in again. You cried out in pain. Though it did not hurt half as bad as you had feared. This was probably because of all the lube he had apparently used. It still hurt though.

Your body was pulled from the wall and slammed back against it with each thrust he made. Here you were. Dressed like a girl. A shameless girl at that. Panties at your knees. Pinned to a wall. Being humped by your best friend mercilessly. You cringed at that thought. "Please, stop! Ah! ... Oh god... Mathew... Ah!"

"Oh God, that's it bitch. Take it. Such a good little whore you are, Doe."

"I'm not, no... Mathew. I'm John. I'm your friend..." But he did not stop. he pounded your ass even harder. "Ahhh! Oh God!" It seemed the more you begged, the hornier he got. Eventually, you stopped. The only sounds escaping from your lips were groans.

As the pain subsided, though, you realized that your own cock ached. It was throbbing while squashed against the wall. You were, to your horror, getting off on having Mathew's cock slam into your ass. At this point, your groans turned to moans. You were so ashamed of yourself though. You felt like filth. Like garbage. Like you really were a slut. You were a slut and you wanted to be fucked against this wall. Or, at least, your body did.

"Mmm, you like that, huh, bitch?" Mathew groaned into your ear as he swirled his hips, stirring his cock around in your ass before pulling out and slamming back in again. "I'm going to fill that ass of your's up, baby. But you gotta beg me for it. You want it, don't you?"

"No," you respond. "I'm a guy. I'm not a bitch." Your moans seem to dictate otherwise.

"You are a girl. A slut. And you want my cum." He slammed in again as hard as he could. His cock burning inside you. "Say it," he said, grabbing your hair and pulling your head back. "Say you are a girl. Say you are my slut and you need my cum!"
