My sister-in-law (brother’s wife) needed a small procedure done on her lower back, so she came to my office after hours. Kristen is a few years younger than me, strawberry blonde hair, a few freckles, and a killer body.

I put her into the procedure room and gave her an exam gown. After getting everything ready I pulled back her gown fully expecting that she would still be wearing underwear, she wasn’t. Her ass was perfect.

After the brief procedure I told her that her ass was perfect – even better than I had fantasized about. We had kind of a flirty friendship. She replied “yeah right” I responded that I had shot quite a few loads thinking of her naked.

She was lying on her stomach and turned over. I told her that I wish we could fuck – it would lower some of the sexual tension between us but there could lots of problems. I pulled her up, so she was sitting on the side of the exam table and asked for a kiss instead. I gave her a slow soft long kiss and pulled her closer to me, my legs between hers. My cock started to stir, and Kristen reached into my scrubs and grabbed my cock. I untied her gown and took off her bra and pulled the gown off. My hands were all over her in seconds. I laid her back down onto the exam table and kissed and licked my way down her body arriving at her completely baby smooth pussy.

I placed her legs into the stirrups and went back to devouring her pussy. A finger placed inside her found her g-spot and she quickly had a crashing orgasm – every muscle tensed up. I replaced my finger with my cock and slowly pushed my cock into her. She was so tight but after a few strokes relaxed. One hand on her ass the other on her breasts pinching her nipples. She moaned and had another orgasm.

I was getting close to exploding and since I wasn’t sure of her birth control status didn’t want to take any risks getting her pregnant. I pulled out and placed my cock into her mouth. She sucked and stroked and within seconds filled her throat with my cum. She swallowed it all.

I picked her up from the table and sitting on the small couch held her in my arms. We kissed some more and after a few minutes got cleaned up. We agreed that this must remain our secret and we agreed that if the situation presented itself in the future, we would do it again.

We managed to enjoy each other a half dozen or so more times before she got pregnant (not mine), and our trysts ended.
