My sister's friend deliberately shows me her panties, she is a total pervert. Even when my sister is sick and in bed, she pretends to take care of her while trying to flash me. After confirming that my sister is asleep, I reach into her skirt and find her panties wet. When we bathe together and I wash her body, my erect dick presses against her ass and crotch, and I can't hide my excitement. She sucks on my dick and lets me record it with a video, becoming even more excited. Returning to my sister's bed, I check on her while inserting a vibrator and securing it with her panties, causing her to stifle her moans in excitement. In a place where no one is around, she strips naked and we film ourselves having sex, making me even more excited. Finally, I ejaculate a large amount of semen onto her mouth and face.
