John pays a visit

You hear the doorbell ring, then some indistinct talk downstairs. Then footsteps.

"I'll never get tired of following you up a flight of stairs," says a deep voice.

Rebeccah's mother laughs, high and excited, and then the voices fade somewhat but not entirely. A back and forth banter ensues which you can't quite make out, when then quiets followed by more indistinct sounds. It might be slurping, but you can't quite tell.

All of this has your mind whirling, and your penis pressing painfully against your cage. You reach into your diaper to try to adjust it but it is no use. You find yourself caressing what you can, getting even more turned on. Your penis is weeping clear fluid into your diaper. As you are exploring yourself, your fingers move further down and brush across your sensitive anus. You've played with yourself there before, and you realize it's better than nothing since you have access to it. You wet your fingertips with the fluid seeping from your penis and a finger easily slides inside you. You hump your little hole with your finger, getting more and more turned on, then manage to fit another finger. You wonder if you can make yourself orgasm this way.

That goes on for a while, but then, across the hall, a low clapping starts, each one punctuated by a breathy yelp. Your arousal clouds your better judgement, and you find yourself quietly opening your door and sneaking across the hall. You realize the door is slightly open, and you are helpless to do anything but peek through the crack.

You can see a man's muscular side and back and he is kneeling on the bed, thrusting his hips hard into the upturned curvacious and perfectly shaped ass of Rebeccah's mother. Your heart is pounding in your chest. On each thrust he is pulling back to the point that the head of his cock, for no other word would suit his massive instrument, is just inside the wet and glistening folds of Rebeccah's mother's vagina, before then shoving the entire length inside her so forcefully that his hips clap against her generous ass, which causes her to whimper or yelp.

The plowing he is giving her would exhaust you, yet he seems unphased aside from a few drops of sweat on his forehead. He grips the flesh of her hips in his strong hands, pounding his thick, rigid and veigned cock into her with a relentless rythm. She is gripping the bedspread tightly in her fists, her heavy breasts swinging violently with each thrust. You are mesmerized and you wish with ever ounce of your soul that you could be John, plunging yourself into her in such a manly way. Instead, your erection pushes impotently into the end of your cage.

You are so mesmerized by the scene that you don't notice for a long time, the mirror above the vanity on the other side of the room. As your eyes find the vanity, you instantly see that Rebeccah's mother has a perfect view of the doorway to her bedroom and her eyes are looking straight at you. For a heart stopping moment, your eyes lock, and a smile curls her lips, though her face is red with passion and exertion. You duck away and quickly sneak back to your room, quietly closing the door behind you.
