Battinson getting sent a possible future or alternate universe and meeting an older version of himself that's with Superman.
They coax Battinson into bed with them. Have a mind blowing threesome for the poor virgin battinson, and send him home.
He falls straight into the older Superman's arm after the portal opens in the sky. And he forgets to breathe for a moment and just takes in the sheer sight that is a DILF Superman.
His suit upholding a regal quality, his huge muscles bulging out everywhere and his deep blue eyes and grey hairs falling on his face and Bruce almost passes out from all the blood that rushes towards his head in mere seconds to turn him beet red.
Before he can process this apparently DILF Superman's hotness, his attention snaps towards a cough coming from beside him and his breath is taken away for the second time when he sees his own older MILF self staring back at him and GODDAMN he's so fucking gorgeous too. His hair is greyer than Superman's and he's smaller than the man of steel but still so beautiful with his sharp grey eyes and lithe body.
He's so entranced by them that he doesn't even consider that he's currently checking out someone who's basically himself in theory.
The older superbat couple see through his very obvious attraction in seconds and they don't even have to coax him into falling into the bed with them.
They have fun with him for hours, taking advantage of his sweet submissive nature. Bruce spends hours eating out his older self's pussy and getting his own pussy fucked stupid by the DILF Kal and then some more when Kal ties them both to a double edged dildo.
He passes out sandwiched between them and wakes up with his mouth around the older Bruce's huge nipples and Kal fisting him from behind.
