I Got It On With My Best Friend's GF With Big Tits While She Was Staining Her Panties in Her Sleep Shiori Satosaki

I saw a stain on the panties of my sleeping best friend's girlfriend, so I secretly touched the stain with my finger. The sticky mucus, thick enough to string, and her disheveled big breasts from sleeping got me so excited I couldn't hold back!! Even though I knew I shouldn't touch her, I did. Gradually, her crotch, which should have been asleep, started getting so wet it couldn't be contained by her panties...
