On LP there is a scene called "Fucking Wet with Jureka Del Mar 4on1 Beer Festival DAP check pissing, piss enemas, piss drinking." There are multiple instances where a guy sticks his cock in Jureka's ass and pisses to have her expel it once he pulls out and these happen throughout the scene so I can't really give you times. This is the most common type of piss enemas on LP where we don't get to see the guy actually pissing but we do see the expulsion.

(Note - I've tried multiple ways to link to the scene but I can't.)

There is a scene on Hookup Hotshot with Charlotte Sartre. It's her second scene on HUHS and it's numbered 94. It's titled "Charlotte's Anal Resurrection." At around 1:11:00 Charlotte is in the piledriver position and Bryan has her pull her ass open with her fingers. He pisses into her gaped ass, onto her pussy and into her mouth. He then pushes his cock into Charlotte's ass. It appears that he is still peeing and I hoped he'd pull out and we'd see her expel it but we don't.
