POV: Ko'd muscle hunk milked through navel and nipple play

You invited this hot, muscled hunk over for beers after just meeting him. While showing him around the house, your friend grabs him from behind and you knock him out cold.
He wakes up completely naked, hands tied behind his back, helpless and confused.
You take full advantage, fingering his deep navel, squeezing and clamping his nipples, brushing his navel with a toothbrush, wetting them, and stroking his cock… then you relentlessly finger his navel until he explodes in a powerful, forced orgasm.
Hot ambush knockout with intense navel fetish, nipple play, and navel-induced cumshot.
