I make her lift weights while I pull my cock and watch, tranced. She's always nude. Her tendons, so tight, so visible, her muscles spin me to the edge of orgasm, for hours. It's really fucking entertaining. She flexes for me, like a bodybuilder.
Ball ache, and spurt.
I let her down to rest on a table. I sit at the foot of her, and sight down along her body, the pointy hips, so sharp, I like to dig my fingers down under them, and squeeze. I can lift her up like this, her bony knees convulse and jab up, elbows table-knocking. I've started a serious relationship with her knees. Walk towards me, in slow motion, bitchy.
