Friends Mom Liked Flashing

When we were kids we had a great group of friends we used to hang with. From 11-15 we were all like brothers. Thick as thieves. Then we got a new kid in our group that moved in the neighborhood. Cool kid. He fit right into the group with us.
One day we were over his house in his back yard. We were waiting for him to get ready and eat his breakfast. While we were waiting, his mother came out to do some gardening. His mom was one of the best looking mom's. Cute face, beautiful rack, nice behind and legs that were shapely and were long.
She exchanged pleasantries with me and my pal Jimmy. She then went to work in the garden with her tank top (no bra) and short shorts. Jimmy and I were drooling and we were both pitching tents. She was bending over right in front of us. We were both mesmerized by her freckled tan cleavage and her nipples poking through the thin fabric of her top. Here we were, two horny teenagers getting the show of all shows then she turned around and bent over. She showed everything. The cheeks of her ass were sticking out then we noticed that her shorts and her panties, if she had any on, were pulled tight into her pussy. We saw her lips and her pubes. She was not shaven. We felt like we were starring in Porky's or Private Lessons! There is no way she didn't know what she was doing. It had to turn her on. When her son finally came out we went to ride our bikes but I couldn't and I know Jimmy couldn't stop thinking up what we saw.
Later on that summer we were having a sleep over at our new friends house. We were up most of the night having fun then we fell asleep about 3 am. A couple of hours later his Dad got up for work. I woke up and saw him leaving. I got up to go to the bathroom and he said you're going to have to wait, my wife is in the shower. I waited and about 10 minutes later I went up. I was walking into the bathroom and the door to the master bedroom was open. I looked in and there was his mom, naked, combing her hair in the mirror. I could see her bare ass facing me, and her tits and her hairy bush in her reflection. Then she opened her eyes and saw me in the reflection peaking at her. She just grinned and continued to comb her hair without covering up. I then went into the bathroom and I jerked off!
