Masturbating to a Close Friend and her Husband

I have a coworker friend. We’re both married. Over the years we got really close and I could tell there was a little something between us. She always lit up when I got to work. We’re playful and flirty at times. Getting close to her I also started to feel attracted to her. I started fantasizing about her while masturbating. She’s cute and petite with small tits and a nice ass. I would look at photos of her and imagine her gagging on my cock, then eating her out and fucking her. Like I said I’m married but I fantasized about her more than anyone else. 

One day at work she was showing me a picture on her phone. In the back of the picture you could see a box of XL magnum condoms. I pointed it out and teased her by congratulating her husband for being well endowed. She blushed and we laughed it off. 

But over time these fantasizes evolved. I started imagining her fucking her husband in front of me. I wouldn’t consider him to be an attractive guy and I’m not attracted to men but I would get aroused thinking about them fucking in front of me. I would stroke myself while thinking about her sucking his fat veiny cock then taking it in her tight wet pussy. I wanted to actually watch them fuck in front of me. Then I started imagining us both fucking her. She’d stroke our cocks, then we’d take turns or fuck her at the same time. 

Then I started imagining her riding me while sucking his cock as he stands above me. I would watch her struggle to take his big dick in her mouth. Her spit and his cum dripping down on me and into mouth. 

Then I started thinking about her using his cum to give me a hand-job. Or I would lick his cum from her pussy after he fucked her. 

Now I masturbate and lick my own pre-cum from my fingers imagining it’s her husbands cum and she’s feeding it to me. Then we’re both sucking his cock and we cum kiss. 

I’ve been edging thinking about my friend and her husband. Sometimes I swallow my cum thinking it’s his. 

This is my new turn on. I act completely normal with her at work, but I’ve been masturbating and fantasizing about her and her husband’s cock. Now I find myself thinking about other couples too. I’ve never had these kind of fantasies before and now they get me aroused immediately. Now when I see them both in person I get a little aroused. 

I would love to read stories about similar fantasies.
