When he came home, he found his wife had already retired to bed, though she had the bedside lamp on and was reading waiting up on him. He stood in the door frame and watched this vision of beauty for a small eternity. Taking in every little detail he loved so much about her.
Finally, noticing the disturbance in the atmosphere of her realm she looked up from her novel and discovered her loved hubby watching her silently and full of admiration. She smiled at him and at the effect she still had on him after 15 years of marriage.
"Go, get changed!" she smiled, "and don't let me wait too long!" she called after him, watching his sexy buttocks disappear. Sighing to herself with a lovestruck smile, she returned to her book although not as concentrated as before.
He went into the bathroom and undressed quickly. Then he admired himself shortly in the mirror. 'Not too bad for a mid-forty married guy' he chuckled. Then he turned around and walked over to the medicine cabinet. He took a little leathery bag out of its hiding place and went over to the sink. He pulled a little chain out and fastened it around his neck. Then he opened the cloth hamper and pulled out some undies. When he found the ones he had been looking for he touched them against the little pendant hanging from the chain.
When the tiny electric shock subsided, he took the chain off, placed it back into the bag and that back into the cabinet, before stepping into the shower and washing down the day's sweat and dust. He towelled himself dry afterwards, brushed out his long hair while blowing it dry and giving it volume and shape. Then he donned the bra and panties and chuckled as the flesh on his chest started to fill up the cups. One last look into the mirror he saw everything was perfect and finished.
She stepped into the door frame one hand on her hip and one arm raised against the frame trying to look sexy. When her wife finally looked up from her book and her wife's look became shocked, she asked: "What? - You said: 'Go! Get changed!' You don't like?"
Her wife looked at her twin which had been her husband half an hour ago fighting for composure and words. In the end, she managed to utter: "It is not the change... it is... the bra! I wore it last week... when... ehhmm... Just, you might want to wear it ... ehm ... the next week... and I think I will have to be you for ... during your time of the month..."
'He' blushed slightly when 'he' caught on what she was trying to say. Then 'he' jumped into the bed and turned to 'his' wife called out laughingly while trying to look seducingly: "Go, get changed! And don't let me wait too long!"
