Not long.....

Ultraboy whimpered and whined as he felt his balls churning, ready to deliver another load just minutes after their first one. Pleasure's speed that he was jerking his submissive slut off increased as he felt his own ballsack tightened.

Ultraboy came first with an increasingly feminine shriek, his cock expelling his cum over the floor and making his already tight ass clench down even harder on Pleasure's cock, triggering his climax as he buried his cock as far into Ultraboy as he could, allowing his potent cum to splash into Ultraboy's bowels, making him groan.

Pleasure softly kissed the back of Ultraboy's neck as his cock started slowly shrinking in Ultraboy's ass.

"I think I have the perfect new name for you, you are no longer Ultraboy, instead you will be known as Femboy! How's that sound?"
