My sister's partner visits my room for self-pleasure

In a tantalizing turn of events, I found myself sharing my abode with the man who was romancing my sister. His daily visits to my quarters were a source of intrigue and curiosity. His routine of self-pleasure in the adjoining room was a spectacle that I couldn't resist observing. One fateful day, I decided to indulge my morbid curiosity and peek through the crack in the door. To my surprise, he was pleasuring himself by fingering my sister's intimate parts. I was taken aback by the sight of her voluptuous and hairy nether regions. The sight was both repulsive and arousing, igniting a fire within me. I found myself drawn to the forbidden fruit, succumbing to my primal urges. The experience was a mix of revulsion and excitement, leaving me with an insatiable desire for more.
