我的继妹从学校回家，躺在我的床上。我自慰，掀起她的裙子，看到她美丽的屁股。

My stepsister comes home from school and enters my room without warning, she almost watches me masturbate, she lies down on my bed, I am so excited to see her in her school skirt, I start to masturbate looking at her ass, I like to masturbate looking at her ass without her noticing She tells me, then she feels the bed move and discovers me masturbating, there is no turning back, so she has to be my whore and satisfy me with her great ass.
