私は下着で自慰行為をしている義理の妹を驚かせ、彼女を激しくファックし、ファックの仕方を教えます。

My shy stepsister usually goes to my room to look for me and she likes to talk to me when she feels bored, she enters my room and can't find me anywhere, she finds my underwear and starts to smell them, when she feels my aroma she gets hot and asks me to fuck her hard.
