Just watches.

Bruce leans on the counter, eating the chicken and waffles he'd just made for Billy. Steve's eyes widen with shock, rage, and--when Billy's tongue strikes particular chord in his tight hole--desire.

Billy stands up, slurping the saliva that had smeared all over his face from eating out Captain America. Billy slides off Steve's shirt, walking over to stand in front of Steve and kissing the larger man's chest, rubbing and suckling on his nipples, rubbing his face in them. the baby pink skin hardening in Billy's mouth. He gropes Steve's pecs, violating and fondling them, twisting the skin until Steve grunts with pain. "You better cut this shit out, kid." Steve growls.

"I can't help it," says Billy, leaning up to suck on Steve's neck while continuing to grope his chest. "You have such mommy titties."

Billy walked back around Steve and used his magic to bend Steve over the counter. Steve grunted with surprise. Billy lines his cock head up with Steve's glistening pink hole.

"Don't you even thi--AUGH!" Steve grunts as Billy pushes his cock into Steve's throbbing tunnel.

Billy fucks Steve, thrusting into him and generating electric pleasure in his lower half.

Billy flips Steve over so that he stares up at the boy. Steve's chest glistens with sweat and Billy's saliva. Billy leans down to suck on Steve's muscle titties while continuing to fuck into the man until his orgasm builds up and he explodes inside of Steve, filling his hole with cum. Steve stares with numb disbelief as Billy leans back and looks at Bruce, who still has his full, large erection firm and ready for attention.
