the rest of the night

Susan enjoyed watching her husband change. The slow enlargement of his, now her, breasts was such a turn on.
"Alan, we're twins!" exclaimed Susan.
"I know. I'm hot." said Alan with a wink, and a slight twist of his body to show off his butt.
"You sure are. I'm glad that worked."
"Me too, periods are terrible. I don't want to go through that again."
"There are some good parts of being a woman, remember?" asked Susan with a mischievous look in her eyes. She started to slowly walk to her husband, slowly taking off her bra to show her 38D breasts. She strutted to her husband and put a finger on his forehead. With a light push, Susan's twin was sitting on the bed, naked.
"..and I am going to show you all of them again tonight...Susan" said Susan slowly walking backwards. She took her hands and pushed her breasts together making a kissing face.
"Susan, you may be getting carried away." said Alan, but his nipples betrayed him. His wife could see he was getting turned on by her show.
"I think you feel otherwise," said Susan while turning slowly and bending over while sliding her pants down her legs to show off her lacey thong she had put on this morning. She kicked her pants towards Alan, who caught them. In that moment, Susan leapt towards Alan, stopping itches from him. She put her fingers on the sides of his face, tracing the outline. She could see his labia minora, looking like hers when she in the mood. Susan put her right hand under Alan's chin and pushed it up to kiss him. It started with a light kiss on the lips, then she used a little more pressure, then after a few more kisses she used her tongue. Alan responded in kind, between light moans.
Susan straddled Alan. The kissing continued and Susan put both hands on Alan's neck and traced them down the front of his chest and eventually to the side of his breasts. Susan took a pause from kissing her husband
"Susan, your breasts are sooooo big," said Susan cupping the breasts and lighting gliding her hands over them. Occasionally, she would touch or lightly tweak a nipple, causing Alan to moan. "I know exactly what you like Susan, and I'm going to do it to you."
"Susan, why are you calling me your name?" panted Alan.
"Because you are Susan right now, Susan." She didn't say anything more before she started to suck at her husband's nipples, gliding her hands around the breasts and tracing the outline of her body.
"Susan, that feels amazing," said Alan as he slowly was pushing into a lying down position. Susan was lying on top of her husband, breast to breast. She started to kiss down his neck, and worked her way towards his nipples with her mouth. While Alan was squirming from the sucking of his nipples, Susan took off her thong. For a few seconds, she played with her own clit before moving her hand to her husband's moist and waiting vagina. She briefly teased his opening with her index finger before moving her hands along his inner thighs. Alan squirmed to try to get his clit closer to Susan's hand, but she kept moving her hand.
"Susan, you have to wait for me to get to the good part. Part of the pleasure is the waiting." cooed Susan.
"It just feels sooo good," moaned Alan.
Susan kissed her way down Alan's torso and mons before licking his clit. Alan bucked his hips up while he screamed "Oh God!" Susan kept pleasuring her husband with her mouth, but introduced her finger into his womanhood, tickling his G-spot. Alan's hips kept thrusting onto her fingers, while Alan kept saying Oh God.
"Susan, did you want something even better?"
Alan nodded between breaths
"I'll get it ready for you.
Susan opened the bedside drawer and grabbed the medallion with her hand. She touched the medallion to Alan's boxers and felt a shock.
