you've been kicked out of home by your landlord for no reason and your friend Melanie allowed you to stay at her house.
Two weeks in she starts to get comfortable around you, even masturbating openly, she most regularly masturbates on the living room couch. Even if you are around or watching a movie together. She just slides down her pants and panties and finger herself like if she was home alone.
One particular day after you come home from work you see her on the couch and instantly know what she's up to so you just mind your own business
Hey Honey how was work?
Ahhhh mhhhh she moans fingering herself. The sounds her activities are making only adding to the awkwardness she doesn't seem to feel
