My sub is on all fours face down ass up with his balls tied up behind him and a spreader bar between his ankles keeping his legs apart. With his cock and balls on display behind him I take advantage of the easy access and milk his cock between his legs, edging him close to orgasm and frustratingly ruining it at the last moment 3 times in a row, leaving his cock to twitch and fire out the spunk unattended below him and give it a few good slaps of encouragement. After the third ruin he is very sensitive and throbbing but I keep stroking the cock while he moans and winces for some post orgasm ...

My sub is on all fours face down ass up with his balls tied up behind him and a spreader bar between his ankles keeping his legs apart. With his cock and balls on display behind him I take advantage of the easy access and milk his cock between his legs, edging him close to orgasm and frustratingly ruining it at the last moment 3 times in a row, leaving his cock to twitch and fire out the spunk unattended below him and give it a few good slaps of encouragement. After the third ruin he is very sensitive and throbbing but I keep stroking the cock while he moans and winces for some post orgasm fun. To end the milking session I plug his ass and leave him restrained for his cock to calm down to a suitable size for locking back in his chastity cage.
