For those just signing on, the first two parts describe my wife's accidental exposure to a stranger, which left me with the realization that her exposure turns me on, and with an increasing desire to expose her again. So far the stories are 100% true, including this one!
*****
Over the course of about a year, I had discovered my desire to expose my wife, how much it turned me on, and how wild our sex became after an exposure. So far, delivery boys had seen my wife's hard nipples thrusting bra-less through her shirts, her bare breasts through her wet, white t-shirt, and her perky little b-cups clearly and unobstructed down her blouse. After the last adventure, as I pulled her skirt up from behind to take her on the stairs, I got an idea.
You see, our staircase is very close to the front door, and clearly visible from it. If she were to leave her purse on the stairs and bend over to get the delivery boy's money, then she might be able to expose her most private, hidden flesh as a stranger watched!
So, one day when we were taking a shower together, I decided to bring it up to her.
"So darling," I said as I lathered up her back, massaging her stress away as the hot water ran through her blond hair and down her shoulders, "what do you say we have a little fun tonight?"
"A little fun?" She questioned, suspiciously, "sometimes your idea of fun can leave me a little vulnerable."
"Oh you know you liked it last time," I said as I ran my fingers down to her lower back, and across her tight ass, "you were so wet knowing that another pair of eyes had been devouring the sight of your bare chest!"
I let my thumbs slip down the middle of her butt crack and slowly massage the outside of her tight little hole. She moaned, and I knew she was getting wet again, from the mental and physical stimulation. She bent over slightly to let me in deeper.
As I massaged her in this way, I said "what if next time we let him see more of you?" She bent over even more as I let my finger slip closer, pressing right against her little hole. "I want him to see you bent over baby," I continued, "I want him to see up your skirt to your bare ass, and sweet little sex." As I said the word "ass" I let my thumb slip inside her ass, and when I said the word "sex" I let my hard cock enter her as well.
She reached out for the wall in front over her to steady herself as I penetrated both of her holes: One with my thumb, the other with my sex. "Yes, fill me, ohhh, I feel so filled up!" she cried. As she said this, I wondered what it would be like to see her mouth being stuffed with someone else's cock as well. I closed my eyes and told her to moan with her mouth closed. As she did, I imagined her moaning against an invading cock. The more she moaned, the harder I thrusted into her. I imagined his hands gripping her hair as he thrust his cock harder and harder through her tight lips. I imagined his cum dripping from her mouth. We both came harder than either one of us remembers.
