You were chatting with your new gf, while your sis was sitting on her phone right next to you. Finally, annoyed by messaging sound, she ask you, who are you chatting with. You show her photo of your gf, and she tries to prove you that she is much better and prettier than her. And she doesn’t like, that you stopped coming to her bedroom every night, as you did before. What if she will wet her pants and let you fuck her, as you loved to go again? Will it make you to forget your gf?
