Anal with Mary

Mary bends over and presents her perfect ass to you. You have no idea how you managed to turn having a small dick into getting to fifth base, but this is a dream come true.

Your tiny erection as hard as it has ever been, you press against Mary's sphincter and gently push yourself inside of her. Mary doesn't react until you start thrusting. "Is it in me?"

For fuck's sake. Mary can't even tell that you're inside of her. Whatever. "Yes, babe. It's in you."

Mary moans, but it's a bit late to pretend that it feels good. Saying nothing would be less humiliating... and yet, humiliation seems to be working for you. You've barely started and already you're on the verge of orgasm. You'd better slow down if you don't want this to be over.

"You can cum inside me," Mary says encouragingly. Fuck! It was the worst time that she could have said that! Taking her suggestion as a command, your pathetic cock blows its load inside her immediately.

You groan an involuntary groan and stop thrusting until your ejaculation finishes. "Did you cum already?" Mary asks incredulously.

"Yes. Sorry babe. I got a little too excited."

Mary assures you that everything is okay, but you can't help but notice how quickly she starts to gather up her things. For the second time tonight, she's about to rush out of your home disappointed.
