Your dick hardens at the sight but balls feel empty. Suddenly, you get an idea in your head.
You quickly grab your brothers head and start shoving him down your shaft. He tries to struggle and break free but the earlier pleasure leaves him a bit weak. You grab hold of him above your shaft, pushing more of him inside. His shoulders soon enter you followed by his midriff and hips.
His struggling doing nothing in helping him escape. Soon, nothing but his legs is left wriggling outside and are slurped up, dropping him nicely into your balls.
Your brother, still dazed from the sequence of events that happened, tries to wriggle out yet it only helps to stimulate your balls even more, speeding up his fate. Your balls, now massive, are barely hanging a few centimeters from the floor.
Their fullness feels too good as you start rubbing them. You relax and decide to sit on them as you rub them. After a while, the struggles inside stop as you feel the bulges smoothen out. Your balls are now filling with cum, with your brother soon adding to it.
You are done in the bathroom and get out, deciding to have fun with your now massive cum-filled balls outside. The question is what do you do with it?
