My pervy brother found a recipe on the dark web to make us switch bodies! He comes into my room and says he has a beverage for me to try. Afterwards I start feeling strange. He made the swap. He is eager to explore his slutty sisters body. He discovers a strange side effect to the recipe. It makes his sisters boobs leak milk! After playing with her tits and ass for a while he decides to take off her panties and sniff them. Mmm they smell so good. He starts playing with her pussy. He knows that she has to have a dildo somewhere and he is eager to stretch her pussy. He plays with one dildo for a while and then switched to an even bigger one. It feels so good he knows he is about to cum. Oh no they are switching back. He needs more time. Sister comes back into her body riding a dildo. She is very weirded out. What happened?!? But she knows her body. She is so close to cumming. She finishes riding the dildo and has one of the best orgasms she has ever had. She has to get that recipe from her brother!
