S3E1: Stepson Backs to Home and Meets with new Stepmom, later at midnight fucks her in share bed

A guy comes home and decides to relax by jerking off a bit. He doesn't know yet that there's a woman in his apartment. She's excited by the stranger jerking off in her living room, but she's a little scared. Having overcome her excitement, she armed herself with a mop stick and went to figure out what the hell was going on. It turned out that this was her new stepson and he hadn't been in the country for six months, so her husband allowed her to live there when she came to town. It turns out that she's now a stepmother and she needs to somehow live together with her adult stepson. It seems that the first night simply couldn't have gone any other way.
