I had Zach tied to the rack, his hard cock in my mouth slowly sucking and occasionally stroking the very tip of his erection. His facial expression looked like he was lost in a state of lust and arousal. He shuddered with pleasure when I sucked or stroked the head, or when I gently teased the shaft with my finger tips. He twitched and trembled, grunted and panted, hanging on the edge, at my mercy. Finally, I told him I was ready for him to feed me a nice big load, then slowly sucked while fondling his full balls until his body twitched, he moaned and shot a full, hot load in my mouth.
