Tim's father Ray walked into the family home after a long day at work, setting his keys and jacket down in their place in the kitchen.
"I'm home, honey!" Ray called out to his wife, Laura.
"In the living room, dear." Laura replied.
Ray walked into the living room to find his wife sitting on the couch, having just put down a book she was reading. Only the person on the couch wasn't Laura; rather, it was his son's 18 year old girlfriend Kelly! However, Kelly looked different than normal, with a style that was very out of place on her youthful body. Her normally long and curly brunette hair was now cut in a matronly bob and she was wearing a conservative red cardigan and what could only be described as "mom jeans". She wore a simple pair of sneakers on her feet, and although Ray could not currently see it she was clad in a plain white cotton bra and matching panties which were clearly meant for comfort rather than style. She wore Laura's wedding ring on her left hand as well as her necklace and earrings. It appeared that Kelly had switching places with Laura just as completely as Laura had switched with Kelly. Of course, the magic prevented either Ray or Laura from noticing the change. To them, Laura had always been a 38 year old woman in a lithe 18 year old body. Seeing her husband, Laura rose from the chair, wrapping her arms around his neck and planting a kiss on his lips.
"So, how was work?" Laura asked, her voice clearly sounding like Kelly but with Laura's mature inflection. The couple discussed their day as a matter of routine, but soon had other thoughts on their mind.
"I just put Chloe down for her nap." Laura said, referring to Tim's baby sister who had been a happy accident for the couple three years ago. "Maybe we have to time to...give each other a little attention?" she stated suggestively.
Ray didn't need much convincing. It had been so long since he and his wife had been intimate. Kissing Laura passionately, he led his wife to their bedroom where they were soon undressing each other with the speed of a couple that had one too many interruptions in their many years of marriage. Soon Laura was stripped down to her cotton bra and panties; they didn't do much to accentuate Laura's hot, youthful body, but to Ray she looked perfect. Tossing her onto the bed, the two lovers were soon making passionate love, being careful to not allow the noise of their tryst to wake their daughter. The fact that his wife was in the body of an 18 year old girl who dressed and acted like a woman twice her age was completely lost on Ray as he pumped into what had been Kelly's tight pussy. The pleasures of their lovemaking soon put both Ray and Laura over the edge, with Ray coming into his wife while Laura writhed in the orgasmic bliss of Kelly's young body. The magic of the watch was leading to some very satisfied customers indeed.
