A little nipple play

The man stepped forward and grabbed both of Alex's nipples and twisted them. Alex gasped at the sudden pain and tried to move away but the chain and cuffs held him in place.

The man continued to twist and pull at them, despite Alex's grunts into the gag. More concerning, he could feel that his dick wasn't shrinking. He tried to kick out at the man, be he expected at and soon a loop of chain around Alex's ankles prevented him from doing it again.

The man laughed as Alex twisted and writhed. He stopped as Alex's nipples were truly aching. "I see you enjoy this treatment, slave." His hand dropped down to rub against the lump of Alex's cock as it stretched the rubber over his thigh.

"Maybe a little too much, eh? Maybe it's time I locked this away."

Alex had no idea what he was talking about and desperately shook his head.
