POV peeking through curtains. Mom catches you peeking in at her & her wife making love... Mom doesn't seem to mind to much she just waves you away a few times. They decide to keep on going, at first, until mom sees you getting turned on and stroking your worthless little pecker (just like your useless father's). This leads to verbal attacks, spanking, threatened castration and finally... mom and lover both straddle your face, one after the other, and pissing on you.
