Sister-in-law lay on my bed, with short shorts punched in the ass, she wants to ... ?

The atmosphere of the house changed completely when she decided to lie on my bed wearing those super short shorts that highlighted every curve of her body. The intention seemed to be just to rest, but the provocative way and the posture in which she adjusted herself left a clear doubt in the air about what was really happening there. I tried to keep my distance and pretend to be a habit, but the proximity and impeccable look turned the environment into a real provocation that was difficult to ignore.
