The shooting is clearly amateur, the lady doesn't want to advertise herself and is wearing huge glasses all the time. Is she skinny? I would rather say she is athletic with a very nice figure. It's a pity they fuck in such unsanitary conditions. If they would have taken a hotel room, they could have made a more interesting video.
She's a skinny woman, but she looks good with her ass, juicy and round. So I think it was not her tits, but her ass that seduced her man! At the end of the video lady so expressively put her anus under her dick, but the man somehow did not pay attention to it.
