I had Zach naked and tied spread eagle to the bed, exposed and helpless, while I sucked his sensitive nipples, neck and balls. His body shook, shuddered and shivered, but he knew enough not to cum, under threat of dreaded tickling. I sucked the very sensitive head of his cock, making him twitch and squirm, so close to the edge. I really worked him over, making him hold on until he was desperate to cum, then mercifully gave permission, sucking him to a very satisfying orgasm.
