afterpiss

the piss used to clear the penal shaft of cum or shit after sex or jerking off. a woman may use the same method after a deposit in her forward hole.
during the afterpiss I hit the toilet tank with a cum/piss mixture due to a semi and the fact it took a moment to figure the combination pressure-to-backsteps ratio needed to ark the fluid into the bowl.

I made the drunk mistake of accidentally rubbing my semi against that m.i.l.f. in the club,fortunately the sweat from my underbag made my balls so slick her toe glanced my bag. so my taint received the full impact,brusing it for weeks after
