The girl was a medical grad doing her residency at the hospital where my wife was head nurse on one of the wards, and as cocky as they came. Convinced that she knew everything and that the nurses should bow before her advanced schooling.
Awkward, since my wife had her doctorate and a host of other honors. The little tease caught my eye at some asinine fundraising event because of her perky little smile, curly black hair, and... other things, artfully displayed in a little black dress with a pair of bright-colored sneakers. The contrast is what struck me more than anything. My wife, short and full-figured, with hips that were illegal in nine states- the girl thin and elegant. My wife's earthy humor, the girl's pale skin blushing at a slightly off-color joke. My wife's deep tan, high-heeled elegance, and bottle-blond hair beside the girl's artfully artless casual look.
When my wife told me that she planned to seduce her I was fully on board. When she got that evil gleam in her big brown eyes I knew I was in for a treat. So for the next several weeks I was a very interested bystander as my wife sloooowly eased the girl into first, some mild lesbian experimentation, and then, the kind of subtly dominant relationship that naturally developed between an older woman and a flighty little girl. I would join her in the shower each day after work, rubbing and caressing and listening to her descriptions of her latest little move in the dance... before I finally dropped to my knees and licked her until she came, trembling, braced against the shower wall.
When she excitedly texted me one day around noon with a picture of the little brunette slut, naked, with a tie around her neck like a leash and desperately licking my wife's pussy as some anonymous guy pounded her from behind... I knew it would be my turn soon.
Two days later I woke to my wife, returning from a late night shift, definitively not alone. I watched as my wife stripped the girl and pushed her to her knees, then I climbed out of bed.
