The one time I strayed from the straight and narrow.
Abbi was 18 at the time this happened, and every single word is true.
Abbi babysat for us a couple of times. My wife and I used to take turns in taking her home afterwards.
One night - my turn to take her back - she was wearing a t shirt that showed off her tummy and her tummy piercing. They were fairly new then, and I looked at the light glinting off it as we drove back. I said something like, "I really like those." Abbi said that she loved having it done even thought it hurt. I asked how they stay on and she told me they unscrew at one end.
After a few moments, I said "Well, I think they're cute. When I see one, all I want to do is kiss it!" To my surprise, Abbi said "Go ahead." I parked up and leaned over her. She in turn lifted her T shirt a little higher. Before I kissed it, I said "You DO know I mean give it a real kiss - not just a peck?" Again she said she didn't mind so I went to work. Light, gentle kisses at first and then some probing with my tongue. I felt Abbi's breathing deepen, and she pushed back in the seat. I guided her hand to the back adjustment and she laid it flat herself.
I repositioned slightly with my right hand on her knees. I probed my tongue into her belly button and gave the slightest pressure between her knees with my hand. To my surprise, and utter delight, I felt her open her legs.
Soon, I was rubbing her over her panties while she was moaning every time I kissed her tummy.
Clumsily, I asked if there was anywhere else she wanted to be kissed, and she gently pushed my head down.
I masturbated her, and more besides. Abbi had very small breasts, and no hair between her legs. It had clearly been some time since she had cum and was more than ready for anything. I am sure she came at least four times- and very messily too!
I was later than usual back home of course, and my wife, being nobody's fool said "So? You fucked her?" It didn't need an answer.
Neither of us got any sleep until the early hours.
Abbi and I fooled around a couple more times before she went off to college.
But to this day, I wonder if my wife fooled around with her too. I would love to think she did.
