Lauri was my best friend's wife. It was wrong of me to want her the way I did, but I did. It didn't help that I was living with them between jobs. I couldn't ask for better friends.
Sometimes, I would catch glimpses of her in her bra or in nothing but a bathrobe. She wasn't a raving beauty but she was pretty, she had curves but the extra weight looked good on her. She had brown hair with big hazel eyes, was rather short and about a size 10. Usually I like thinner women but she had a rack on her that wouldn't quit. I often wondered what she looked like naked. I fantasized about her every time I caught a glimpse of her cleavage as she bent over doing housework. Some nights I would jerk off thinking about her. I knew that she was sleeping naked in the next room with Jeff.
One day I was playing a video game on my laptop. That always killed my back since I had to use a TV tray and sit on the futon where I would bed down at night. I could hear Jeff watching football in the other room. I thought about joining him. I snapped the laptop closed and groaned and stretched.
"You need a back rub?" she startled me; I didn't know she had been watching me.
"Sure!" I never gave up a chance for a back rub from her.
She really knew what she was doing. She had taken a few courses in massage. She climbed on the futon behind me, straddling me. She smelled so good, simple and clean, like soap with a hint of musk. Her hands were strong on my shoulders and back. She worked on my back confidently. I was very aware of the closeness of her body, her breasts occasionally gently pushing up against my back, the inside of her thighs pressing gently against the outside of mine.
To my embarrassment my cock started to swell. She was behind me and couldn't see so I shifted a little so I wasn't straining quite so hard against my zipper. She continued to knead my shoulders and back getting all the knots out. My shoulders were particularly tight so she got up on her knees and dropped an elbow into my shoulder, unfortunately that gave her a clear view into my lap. I heard her gasp slightly and nearly died of embarrassment as I looked down to see some pre cum had seeped through my pants making a dark stain there and my cock bulging against the crotch of my pants..
