I swear he asked me to do that. He was very horny that day, he prepared ropes, ballgag, and face mask. All I had to do was to tie him up and give him some pleasure with my hands and mouth. His cock was hard as fuck and a tip of it moist from precum. I clipped his nipples and started to tease him, a bit of tickling and frenulum teasing, also sucking him deep. I've let him cum eventually and then I tormented him with post cum wanking!
