I went to a party once at an artist's studio where there was this muscle god with a huge cock, laid out face up on a massage table, naked except for a blindfold, and with his hands restrained. There was a little card attached to him that listed things he liked, and things not allowed, and supply of lube, lotions, and sensory toys. So we played with him all night, nipple play, muscle worship, caressing, sensation play, etc. He was hard much of the time, and finally someone stroked a big wet load out of him. Then the blindfold came off, he cleaned up, and we all sat in the kitchen having cookies and milk (not his), while he tried to guess who did what to him.
