My sister had just gotten her wisdom teeth removed. my mom dropped her off at the house and told me to watch her while she was at work. she had some medication and she was out cold. being just the two of us at home alone, I wondered what panties she had on. (I had a panty fetish and I always jerked off with her panties.she was in a loose sweatpants and tank top. I pulled her pants off. I was actually very surprised because one, she was wearing a never before seen gstring. Yellow with white polka dots. and two, it was pulled to the side and her pussy lips hang out. it was so smelly but a sweet scent. and her virgin pussy was so pretty. I made sure she was really asleep, before I remover her tanktop an bra. she was fully naked. I took some pics saving them to jerk off later. I took her panties and licked them clean. it was a familiar taste, being used to her other panties. then I went for it. I licked her pussy, sucked on her nipples, and even fingered her ass. I was scared of penetrating her heymen or what ever its called so I didn't enter her pussy. eventually I teased myself enogh and forced my dick in her mouth. I shot my first load all over her face. then I waited, and redid it but I shot this load over her stomach. for the last one, I got off but massaging the head of my penis on her pussy lips. but I shotmy load over her mouth. I took more pics. I cleaned up and redressed her, but, I kept the yellow panties. she woke up not suspecting a thing, except for a weird taste in the mouth.
