After a nasty divorce where I lost everything, I was offered to move in with a friend of mine from work. Living in their finished basement I had it to myself, and used to hang out watching TV with them in the living room till they went to bed.
His wife used to walk around the house all the time, wearing skimpy clothes, both when her husband was around and when he wasn't. She'd flirt with me and mention things she and her husband would do. If I was doing dishes, she'd brush up against my back with her big 42D tits (I only know because I helped do the laundry, and I'd seen her bras.) even though there was plenty of room for her to pass by. She would occasionally come in and use the toilet while I was in the shower. (It's their house after all.) They had one of those clear shower curtains; I'd catch her looking at me, and she'd turn away as if she wasn't.
One night, while he was sleeping because he had to go into work early, she and I were sitting up watching some cheesy horror movie. I told her I was tired and I went downstairs to my room to sleep.
About 1:30ish in the morning after he left, she came downstairs, butt naked. She was on her knees next to the bed and I felt the sheet being lifted off of my pelvis. I sleep naked all the time. I woke up to feel her mouth on my cock, with her tongue swirling around the head as she sucked on it. I gave a half-hearted protest but she put her hand on my mouth to shush me as she did her thing showing me her oral skills, Which were fantastic, as she fondled my balls.
I could hear her fingering her sopping wet pussy as her mouth slid up and down on my cock. I could smell the sweet scent of her, which only made me harder. I was able to mumble I was about to cum, and she sucked harder, taking my cock in her throat, swallowing every drop of my load. She got up and whispered "sweet dreams" in my ear and placed her wet sticky pussy cum coated finger on my lips.
That was the first time of many experiences we had together in the year I lived with them. I saw him the next day at work. He was leaving as I got there, and all I can think was... Should I tell him what happened? I obviously didn't want to break up his marriage, but her mouth felt so good on my cock, and I definitely wanted it more. I decided to just keep it to myself, thinking it would be a one-off thing.
I completed my daily run, and when I got back to the house he was napping on the couch. She was wearing a low cut sundress, that barely contained her huge tits. She gave me a sly grin, and went about cooking dinner. I was standing at the sink washing my hands, when I felt her come up behind me and push her tits against my back, and she put her fingers under my nose. She had obviously been finger fucking herself again. I flicked my tongue out to taste the dry pussy cum off her fingers. As we sat on the couch watching TV and eating dinner, he told her the overnight run was going to be a permanent thing and that he was happy to have me there overnights to help keep the house safe. She had a kind of a bummed look on her face, but at the same time looked over at me with a slight grin on her face, jokingly telling him, "He'll be my protector while you're gone".
She grabbed the dishes, and went back into the kitchen, as him and I sat there watching TV and shooting the shit about work. I felt my phone vibrate from a text. All it said was: "Last night was just the beginning".
All I could think about while sitting there talking to him, was what else she had planned. I started thinking about the moral implications, and what would happen if he found out.
