Backstory - I’m 35M married with 3 kids and have been having an affair with my coworker’s younger wife Sara (24) for a few months, most recently yesterday at a Thanksgiving party. I’ve posted other parts of this story in other forums. I can’t tell any of my family or close friends, so figured I can share online. I’ve been married for 10 years and have never cheated until recently, so I’m a bit nervous. Sara is very petite, about 5’1”, 100lbs, blue eyes and tan skin. I’m pretty fit, 6’, brown hair and blue eyes.

My wife went out to get her hair done today, she’s usually gone for a few hours. My kids were at my in-laws since yesterday morning so I had the house to myself. I started thinking of the amazing sex I had with Sara on Thanksgiving. Typically I meet her maybe once every week or two, but today she texts me out of the blue, shortly after our meet up yesterday. We chat for a few minutes and I tell her to come over, her husband left this morning for a business trip.

About 20 minutes later my doorbell rings. I had just got done texting my wife, her hair appointment had just started so I knew I had some time. I answer the door and Sara walks in, not saying a word but smiling at me as she walked by. She was wearing a large winter jacket, almost trench-coat style that I had never seen her wear before. It covered her entire body from her shoulders down to her knees. My heart started racing with excitement, wondering what she was wearing underneath.

As I turned around from the door to gaze at her, she unbuttoned the coat belt and opened it up wide, but not dropping it. She was wearing nothing but her newly acquired panties. She had on no bra, and the panties were those that have side straps that hug the waist/hips with a cut out crotch. She stood there holding the jacket open, exposing her perky breasts and waxed pussy, her thigh gap looking extra wide today.

Needless to say I didn’t speak, I walked over to her dropped her jacket out of her hands, kissing her neck and running my hand down her abdomen to her pussy. I could feel her grinding it against my fingers. I picked her up by her ass and carried her up the stairs to our guest bedroom (I didn’t want her scent on my master bed for my wife to discover). Her bare pussy rubbing against my shorts on the climb up made me rock hard. I sat her down on the bed but she immediately got up, swinging me around and tugging down my shorts. She pushed me back on the bed and climbed on after me, spinning her ass around and sitting it down on my face while she sucked me off. It was the perfect 69. Her pussy tasted so good, almost sweet. She went extra hard on my cock, deep-throating it harder than normal, her spit ran down her chin onto my cock and balls.

We kept at this for a few minutes until she sat up, working her body down and sitting on me reverse-cowgirl. When she slid down on my shaft she didn’t even take it slow, she went full speed. I expected her to take it slow but she wanted it hard. I let her have her ride. I grabbed her ponytail and pulled her head back while she fucked me, reaching my other hand around and squeezing her throat (lightly). This seemed to make her fuck me even harder. Usually our sex lasts for 20-30 minutes or so but she squeezed this one out of me quickly. I exploded inside of her, filling her up so deep I could feel the pressure of my seed trying to force its way out. As I mentioned before, Sara and her husband are trying for a baby, she’s not on birth control so I’d love to get her pregnant and give them a baby, us secretly knowing it’s mine.

When she climbed off she immediately turned around and started sucking me off, trying to clean off all my seed. Never had that happen before, it was so damn arousing, even after I blew my load. We cleaned ourselves up and went back downstairs. As she was putting her jacket back on I could see some of me still leaking out of her pussy, it was fucking amazing. She just left my house shortly afterwards and I had to hurry to clean the place and shower before my wife got home.
