It feels so good

Mar...Mistress slowly pulls out until just the tip is inside you, letting you feel the entire length as she does, like having the most pleasurable bowel movement ever. She's soon all the way back inside of you, slowly developing a rhythm as she fills you up and empties you out, over and over again. It feels better than you imagined that it could, and soon your tiny penis is fully erect again, such as it is.

'When in Rome', you figure, and reach down and begin to stroke your newly revived manhood. It doesn't take long for Mary to notice and slap your hand away. "This is for me to get even, remember? You're not supposed to cum before I do!"

She's right, but it's so hard to resist playing with yourself when you feel this good. Even Mary seems to be getting off on this; you can hear her breathing start to become ragged.

Mary slips a hand between her folds and starts to rub her clitoris as she quickens her pace inside your ass. The suction cup from the vibrating dildo keeps pushing her fingers away, and she finally notices that she can adjust it so that she can feel the vibrations against her clit. Then she learns how to adjust her thrusting to take advantage of it.

Mary is now thrusting at an angle in order to keep the vibrations on her sensitive clit, which makes it less comfortable for you. Or maybe it's still okay? It's not just sliding in and out smoothly any more. Now it's distinctly pushing downwards towards the couch, towards the front of you, towards... your prostate! Oh yes! I mean, oh no! I mean... you don't even know any more.

With Mary thrusting harder and harder, grinding her clit against the vibrator, there's no way that she's going to stop now. If she doesn't, you're going to cum. What would it say about you if you came from getting fucked in the ass? Would she still respect you? Could you still respect yourself?
