UGSS-062 - My half-assed mother wiggles her butt without taking off her pants. She gets excited by making panties stain when I look at her erotically...

When I got home from school, what caught my eye was my mom writhing in agony, unable to put on the skinny pants she had just bought! ``Ken-chan, please take off your pants◆'' I was begging her to help me, but when I saw her sexy hips flexing right in front of me, and her ass sticking out of her panties, I couldn't bear it anymore and got an erection! That! ? But mom also has nasty stains on her pants! !
