Ass to mouth

Adam tigtens the restraints, keeping Robert helpless. He then lifted Robert up on the bed and moved him around so that he was laying on his back, head hanging out over the edge of your bed. He then pulled out the plug and put his cock at Roberts open mouth. He briefly wondered of his cock would get to big for the ring gag, but that thought went away quickly.

"Do you know how your ass tastes Robert?" He asked, but before Robert could even try to answer he rammed his cock down his throat, pressing down for a few seconds while Robert thrashed as best he could. Looking down, Adam could see Roberts throat bulging around his cock. Wasting no time, Adam built up a fast and hard pace, slamming his cock down Roberts throat without a care in the world.

As he fucked his throat, Adma watched as Robert shrank. His mucle mass kept reducing, his legs got a bit shorter, his hips widened and his cock shrank to a pathetic 1 incher. meanwhile Adam saw how his body grew and grew, and he felt Roberts throat tighten around his growing cock. Robert stopped thrashing about, and Adam pulled out and crouched down. Robert had passed out, so Adam slapped him hard, getting a groan in response. Robert then started coughing and gasping for air.

Once he´d stopped coughing and gasping, Adam pulled him of the bed and grabbed his hair, making him look up. His face was red, his eyes bloodshot, and half his face was covered in tears, spit and pre-cum. Adam unbuckled the gag to reveal his whole face. He could still recognize Robert, but if he´d walked in like this you´d assumed he´d eiether gotten fucked all week or just visited a plastic surgeon. His strong jawline had slimmed down, his lips were thicker, his eyes bigger. His nose was still mostly the same and his hair hadn't changed much, although it felt softer.

Adam put his spit and pre-cum covered dick over his face, loving how big it had gotten. Before he'd fucked his throat he'd been a good 11 inches, now he was a very thick 13 inches.

He smirked and slapped Roberts face with his cock. "Looks like you aren´t bitch enough to take this cock. Yet. But I´m gonna cum down your throat, whether you like it or not."
He moves his cock and places it at Roberts full lips. "If you suck it yourself, I might not get so tempted to fuck you **** again. You have five seconds to choose."

Robert looked up in shock at Adam, his mind going a hundred miles and hour trying to decide quickly before Adam fucked him **** again...
