This guy spent the night with his girlfriend, and the next day the girl had to leave early for class. So the boy was left alone in the house, well, not completely alone. His sister-in-law was in the other room. So he went into the bedroom to wake her up. This bastard cheats on his girlfriend with his sister-in-law and doesn’t even bother doing it in another house. Of course, the sister-in-law is also a shameless one who eats cock without any fault. This is nothing new to them, they have already had morning sex several times when the girl leaves.
