It seems like that’s all the time anymore. I leaned over to kiss you as I ran my hand over my cock. But as I kissed you gently, your hand took the...place of mine. Your fingertips teased the head as you gently played. We kissed more forcefully. My hand moved over your breasts. Both nipples were very hard and sensitive; almost leaning into my touch. I put my lips on one nipple. I sucked and gently bit. You moaned with approval as your hand was gently but with increasing speed moving up. " I put on a playful smirk, "I forgot them at my house." He looked at me knowingly, "Both you and I know that's not true, but since I want to see that nice ass jiggling as I imagine smacking it as I ram my dick so far into your tight pussy, I'll let it pass. Just this one time." As he said that last word, he winked. I swear if I was some giddy little girl I would've squealed and fainted, but since I'm not, I smiled invitingly and started running, my skirt hiking up a few inches. I could feel. All I remember is her touch and the feel of her breast pressing into my chest. I also remember going to her and pulling her face to mine and began to deeply kiss her and caress her body. I remember gently turning her around so her back was to me and sliding my hand down to her perfect little mound. Her pussy was so hot to the touch! My finger gently slid inside her pussy which was already very wet and inviting.I then gently pushed her leggings down over her beautiful curves and in one seamless. A long drive, followed by a tired evening, had not led to what I thought it would. I was expecting sleep somewhat early in the evening.What happened instead was far from sleep. A very heavy, very sexual encounter between my step-daughter's friend Katie and I occurred, long after my step-daughter and wife had gone to bed. The first encounter, very physical and very taboo, led to another encounter the following night.The last sight I had was Katie walking up the ladder from the hot tub. I starred.
