HUNTB-449-Uncensored-Leaked — I saw it! My sister was practicing cowgirl position and internal orgasm with a dildo! Her serious practice was so erotic! What's more, the dildo and my erect penis look exactly alike.

My sister, who has never experienced an orgasm during sex with her boyfriend, buys a dildo online to practice internal orgasms. Sexy sounds leak from her room... I sneak a peek and the practice scene is so erotic that I can't help but masturbate, and my sister catches me! Then she comes over to me and is surprised to see how similar the dildo and my erect penis are, and asks if she can try it! My sister experiences her first internal orgasm with a real penis. And then she says, "You can cum inside me," and I also experience my first internal ejaculation!!
