My wife Jan and I decided to take a car vacation through the mid west, which included a one-night stop in Kansas to visit with Jan's sister, Jane and her husband, Al. Bringing readers up to speed, Jane visited us a year ago. I had always had an attraction for her and it turned out the feelings were mutual. For a mature woman, Jane was very innocent when it came to sex beyond her marriage and even then, sex with her husband was at best, very routine. The inevitable happened. I opened her up to some real erotic and stimulating sex and eventually Jan demonstrated what two women could do even without men.
After an all day drive we pulled in to their driveway in late afternoon. It has been over a year but the sight of my "plain Jane" sister in law made my heart skip a beat and my cock stir. Our family always greets with a kiss but my kiss with Jane was deep, full and long. Of course Jan noticed but she loved us both and knew her sister's situation. She was glad I could teach little sister some things but also knew our marriage and sex was solid.
Al traveled a lot but was due back later in evening. Jane had a good home cooked dinner in preparation but realized she was missing a key ingredient. When she excused herself to run to the store, I volunteered to accompany her, as Jan had a splitting headache from the long drive and needed some prescription relief.
After Jane returned from her bedroom, we left on our errands (and hopefully more). Jane had changed into a brief, loose fit, summer skirt instead of her usual jeans. As she slid into the car her short skirt briefly rode up her legs, exposing those creamy thighs I yearned so much to feel and explore.
"How are things going with you and your new liberated social life," I inquired.
"Not so good," she replied. "I have hinted around to Al and made some pretty strong overtures but he is just too straight laced. I do love him dearly but I yearn for more variety in our sex. I need so much more than he's willing to give."
At this point my left hand casually found her thigh. We both took a deep breath as she continued driving.
"Jane, I'm sorry about Al but I want you to know how much I've missed you and I couldn't wait to see you again if only for one night."
"I've really missed you too Dennis, but we really don't enough time to be alone."
"How about right now," as my hand slid under her skirt and slowly moved up her inner thigh.
"Are you serious. In this mini-van?"
Now my hand found its destination and to my surprise, my innocent sister in law was not wearing panties!
"You little vamp. You're not wearing any panties and looks like no bra either!"
Jane's purred with a sly smile, "Just for you, my hot brother in law."
At first my hand softly rubbed against her mound of Venus then ventured on as Jane relaxed and opened her legs. My middle finger found its way through her moist vagina lips and into her already slippery, warm pussy.
