俺は俺の部屋で宿題をしている義理の妹を驚かせて、俺たちは激しくファックしてしまった。

My stepsister is very judicious in her room making her school commitments since they are finishing the year and she has many late commitments and missed subjects. I surprise her in her room and distract her so I can fuck her and finish her homework in a better way.
