Shoulderbladin’

His back muscles were broad and firm and slick with sweat. He flexed his back and shoulders for Teddy, making him shiver with desire. It produced a little valley between his shoulder blades. Teddy slid his cock between the valley, the slickness of the sweat gathering there making it glide with no friction. He held back a moan, not sure if that would embarrass Buck.
“Man, in county lockup back in Oklahoma, I was there for like a month,” Buck said, no longer watching the movie because the pretty lady was gone. “And they done that, whatchoo doin’ all the damn time. Indian fellahs love it, they do it a bunch. Shoulderbladin’.” He shrugged, unaware of how that sent a wave of friction and pleasure up Teddy’s spine. He laughed too, making Teddy’s cock spasm and leak precum onto his skin. Buck said, with kind of an embarrassed-little-boy leer, like he was tattling to his mother, “This one time I let like ten of ’em do it, and they all nutted in my hair. It was like wringin’ out a sponge.” He laughed sheepishly.
