This happened a few months ago.

My wife’s friend had come in to town to hang out with her for a weekend. They’ve been friends since high school and are now in their mid 40’s. She lives several hours away so they don’t get to see each other often.

This weekend they had been out to dinner and decided to hang out at home that night and just drink some wine and chat. I was around and joined in the drinking. After about an hour her friend excused herself to change. When she came back into the living room I couldn’t help but sneak glances at her. She’s pretty, with a really nice body, and was wearing a t-shirt and shorts. From certain angles it didn’t look like she was wearing a bra, either.

We all moved to the living room and my wife promptly fell asleep while we were watching TV. I kept sneaking glances and noticed her nipples had gotten hard. Definitely no bra! At one point she shifted positions on the couch (she was sitting across from me) and I could see up the leg of her shorts enough to tell she was wearing black underwear.

I had to shift my position, too, because I had begun to get hard from looking at her. She continued to move occasionally while watching TV and each time I got a peak up her shorts. I thought I was being smart with my glances but she realized what was going and after one of my looks I glanced up and she was staring right at me.

I thought she was going to say something but she just smiled and parted her legs more. I glanced at my wife and saw she was still sound asleep. I looked back at her friend and she purposefully glanced at my crotch and then back up at me and smiled again. Then she dropped one hand to her lap and eased the leg of her shorts open. She slid her panties to the side and I could see all of her.

She ran her finger up and down her slit and then inserted it. She proceeded to finger herself right in front of me and after a few minutes her breathing quickened, her nipples got really hard, and then she shuddered with an orgasm.

I sat there, stunned, with a raging boner in my shorts. She stood up then, and walked quietly over to me and held her finger under my nose for me to catch her scent and then traced the outline of my lips. She whispered "your turn" and grabbed my wrist. I caught what she was suggesting and moved my hand down into my shorts and grabbed my cock. She continued to hold on to my wrist and began to move my hand up and down, jerking me off with my own hand. I didn’t last very long and came hard in my shorts and all over my hand.

She let go of my wrist then and pulled her hand out of my shorts. I could see some of my cum on the back of her hand. She locked eyes with me, raised her hand to her mouth, and slowly licked her hand clean. She then went back to her spot and I slowly got up and went to change in my room. When I got back my wife had woken up. We all decided to call it a night and went to bed. The next day was normal with no hint from her that anything had happened the night before. To this day neither one of us has mentioned it and there’s been no repeat.
