The girlfriend found an old bottle while cleaning. She got it years ago from her grandmother, who was a little weird. There is a magic potion in the bottle that should turn a man into a woman. The bottle label says that if a man d-r-i-n-k-s a potion, he becomes the woman who he last kissed. The idea is ridiculous, the girlfriend thinks and hurries to take care of her affairs, giving a kiss to her boyfriend. When the girlfriend leaves, the boyfriend decides out of curiosity to try the potion. ”Don’t think that causes any harm” he thinks and takes a sip from the bottle. However, something is happening, the boyfriend starts to shake and soon he notices that he has the body of his girlfriend. He looks exactly like his girlfriend. He goes to examine himself on front of a mirror. Curiosity grows and he also wants to try on his girlfriend’s lingerie and try what a dildo feels like in him or should say, her new pussy. In the middle of horny masturbation, some man comes next to him (or her). The man is boyfriend's (in the woman’s body) best friend Jack. Jack got in because girlfriend had accidentally left the door open when she left. Jack starts to get closer. That’s when the boyfriend (in the woman’s body) realizes that Jack has fucked with his girlfriend. The boyfriend (in the woman’s body) gets confused, and decides to take revenge on his girlfriend. He (in the woman’s body) lets Jack fucks. This is the way how boyfriend can cheats his girlfriend too. Jack is little confused because he still thinks the woman is his best friend's girlfriend who is just a little spaced out. Jack has missed his best friend’s girlfriend's pussy, so Jack only wants to fuck. They fuck and Jack shoots a big cum into his best friend's pussy, which he still thinks that it is his best friend's girlfriend’s. However, he gets to know the truth at the end when he hears the voice of his best friend’s girlfriend when the girlfriend comes home. A MAN IN A WOMAN'S BODY. CREAMPIE. Different angles.
