My sister's friend, who always shows off her panties in her miniskirt, came to visit my sick sister in bed. When I peeked into her room, I saw her panties again. She knows that I'm always peeking at her, so she's a little devil who shows them off on purpose. She invites me to stand next to her while she's asleep from the medicine, and when I take a good look at her transparent panties and crotch, I can see that she's excited. I'll use a toy to stick it in her lewd crotch and get her even more excited. Of course, I'll use my overly erect dick too. When I insert it next to my sister as she sleeps, she suppresses her voice and gets excited. I had a lot of fun with her big-breasted erotic body.
