He invites him in and starts giving him a blowjob
He walks down the hallway and after hearing some noises, he decides to go investigate. What seems to be something strange is something very normal for the women of their house. Or the place where his mother-in-law allows him to live, to be exact. When he knocks on the door, he hears his sister-in-law invite him in and at once, without saying any more words, she starts giving him a blowjob. He is not the one to refuse, it would possibly be counterproductive for him. Then he lets her do whatever she wants with his cock and once she’s ready, he starts penetrating her pussy. It was probably because he wanted to fuck.
