Struggling Alone

I've been with Sarah for two years now and we're pretty much perfect together. She's amazing, caring, but there’s this one thing I can’t stop thinking about. Masturbation scenes where she’s not here to witness it. It’s a private kink of mine that no one else knows about, and every time I find myself in a dark room, alone, with only my imagination guiding me, it feels like a guilty secret. Tonight was different. The apartment was quiet; Sarah had left early for her night shift at the hospital. As soon as she closed the door behind her, I grabbed my laptop and found some videos that matched what I liked, women in submissive roles, bound and helpless. It turned me on more than usual tonight because it felt like a forbidden act. I started touching myself, imagining Sarah was there watching. Then I moved to fantasies of being watched by someone else, another woman, tied up and at her mercy. The physical sensations were intense, every nerve ending alive as I worked my body until release came crashing down inside me. It felt so wrong yet strangely right.
