Mount Vitruvius

In position.
My erection and balls against the wall.
Arse out, and proud.
Hands, feet, splayed.
Displayed like Vitruvian Man.

The crop strikes me.
The sting is good.
Jerk forward..
Cock grazing brick.
Hot, hard, flesh meets cold, hard, brick.

Second thwack.
More sting, more keen.
Cock harder than brick now.
Pain/pleasure growing.
Maintain the position.

Three. Four. Five.
Thwack! Thwack!! Thwack!!!
Pain builds, pleasure wains.
Christ! She's really hitting me.
It's really hurting me.

Maintain the position.
Six. Seven. Eight. Thwaaack!
Fuck. Cheeks sting like fuck.
Definitely pain defined.
Cock, grazed raw, shrivels.

Thwack nine.
Sweat pours down back and chest.
Cock, now a peanut.
Balls shrunk to kernels.
Corporal punishment.

Losing position. Vitruvian dissolved.
Thwack ten is a glancing blow.
Cocks; balls; arse; legs; arms; pride.
All shaking. I've had enough.
Weakness is my grave.
