Excuse Plot: A gym jock bunny with an embarrassing little disability attempts a new form of working out. You know, for developing stamina and arm strength and that sorta good stuff. Looks like a combination of an undersized gym outfit, a long workout, and those extra absorbent diapers has lead to a very potentially humiliating situation.~

Or I just wanted to draw a muscley bun in massive diapers and a tiny singlet. -shrug- Either way, my attempts at perspective are awful.
Edit: Changed a few details. F5 and all that.
