Sister in law
This past year the wife & I lived with her sister and I grew an obsession with her, got to the point where I would smell and masturbate to her dirty underwear. Their would also be times where she would have underwear on her bed that she plans to change into and I would cum into them.
During the summer we would sleep with our door cracked and one time I went in there while she was sleeping and masturbated while she slept, so close to wanting to cum on her face. There was one time it got to the point where I tried to pull the covers off and she woke up and I ran out, luckily I convinced her she had a “vivid dream”
