Trattenuto dalle palle e mungitura rovinata da dietro

Rod is on all fours. I tie his balls with a long ribbon tucked through his legs behind him and up to the ceiling, his cock is also hanging behind his legs tucked in-between them. His legs and knees are strapped together so his cock won't pull back through. Once restrained, his cock is at the mercy of my latex gloved hands and my fleshlight which I use frustratingly to edge his cock with, ruining each orgasm that comes his way and letting the spunk dribble out on the back of his legs.
