She tells me no and I jump into the bathroom leaving the door a little ajar and pull off my pants. I am not super human in strength or have the body building type of frame, but I am well built and even more important I was blessed with thick cock that has enough length to make a woman gasp at the sight but not think I should be a porn star. I turned to give off a decent view and pulled off my pants leaving it hanging there hoping she would get a glimpse. The idea worked because she came around the corner and looked through. I know she saw because we made eye contact and just as we did, I pulled up the bathing suit and walked towards her. As I passed her, I swatted her ass and said I would be out back and that she should really consider joining me.
I jumped into the tub and began to relax and doubt whether my plan would actually work. I know Lisa is attracted to me but she is just to caught up in being morally correct that she could never take flirting to the next level. I positioned myself so I could see into windows on the second floor and watched as Lisa came up to the window to look at what I was doing. I noticed her and waved her down and she turned away. A few moments later she was outside wearing a towel and told me that no matter what she couldn't get her hair wet.
Because Lisa is a bit prudish, I expected this unattractive one piece bathing suit so you could imagine my surprise when she dropped her towel to reveal a wonderfully revealing white bikini. I looked at her and told her that she was entirely too sexy for her own good and that she looked fantastic. She told me that she had purchased this bathing suit to impress her husband but knew I would like it more. She sat across from me and stretched her body out. Her toes, painted red were about three inches from my feet and her breasts were popping up out of the water, the white having becoming like she was naked, her nipple pink and erect. This immediately got me excited and I thank god that at that every moment I was underwater and surrounded by the increasing number of bubbles the jacuzzi was producing. I offered her the massage and she moved towards me, spinning in a half circle so that her ass was in my crotch and her back against my chest. She gasped a bit and leaned harder against me. My erection which was small at the time immediately started pushing back against her and my hand went to her stomach. She placed her hands on my hands and intertwined our fingers and slowly moved it up her body to her breasts. I took my cue from there, slowly feeling the edges of her bathing suit, playing with her breasts but not touching her nipples. Slowly I caressed her chest, moving up her neck line and down, ignorning her swollen nipples as I continued to press my cock into her magnificent ass. My lips, kissing her back and the flat part of the back of her neck where he shoulder blades split. Spinning her around, she locks her legs around my back and tells me that nobody can know about this. I kiss her mid sentence and whisper I know while untying her bikini top and throw it to the deck outside the jacuzzi. Lifting her up she reaches down between my legs and starts to massage my already aching cock. She tells me that I am so much bigger than her husband and that she can't wait to experience me. I lift her off and she pulls my bathing suit off and almost simultaneously pulls off her bikini bottoms. She straddles me as I take a nipple into my mouth and slowly rub my cock against the lips of her pussy.
Flicking her nipple in my mouth for a bit I switch my tactic and lift her up and place her ass on the top of the outside edge of the Jacuzzi. Her patch, neatly trimmed and shaped like a triangle sits exposed as I position myself to go down on her. Her lips are glistening with moisture as I begin to trace my tongue around her mound. Opening her lips I let my tongue dance across her clit, flicking and licking as I vibrate the letters of the alphabet. Every third or fourth letter moving my tongue down and darting it inside her before moving back to continue my ABC's. Grabbing my hair Lisa starts to buck her hips against my face screaming at me to tongue fuck her and I can do nothing but oblige. I stiffen my tongue like a board and pound it into her opening while at the same time reaching up teasing her clit. Bucking and thrashing she erupts into an orgasm and collapses into the water sending me plunging to the bottom of the jacuzzi.
I surface with a smile on my face but not done experiencing my sister-in-law. She begs for me to stop but instead I lift her hips up and enter her with soft and shallow pumps of my hips. Switching to gyrations I dive deeper, letting my cock explore until I get the response I want. Lisa wraps her legs around me once more and we move like we have been together for years. Pumping and moving like one until I explode my seed and collapse into each other. Kissing softly and holding each other, both wondering how we can repeat this, but at the same time keep it a secret.
