His business trip was over and he was about to be in bed with his wife for the first time in a week. Her trip to the diet clinic had also kept her out of touch as well. They both wanted this but, as he was about to find out, for different reasons.

She was waiting for him in the bedroom, already under the covers. He could not see what she was hiding but he knew she only did that when she had a surprise for him. He did, however, see what she had put out for him to wear.

"I know how you like to wear the nightie and panties sometimes, so I put some out for you. They're your favourite, aren't they? I really want you to wear them for me tonight."

She normally did not insist like this but he did not want to waste the opportunity or spoil the moment. What surprise was waiting for him under those innocent looking sheets?

He got into bed and reached for her. She was wearing one of his T-Shirts and pyjama bottoms, a look so common for him. As he caressed her she did the same, first his chest and then down the nightie to his panties. He was rock hard and enjoying the feeling immensely.

"I can tell you're excited, as am I." she said cryptically. Curious, he reached for pajamas and stopped. Where there should have been a soft cleft, moist with juice, there instead was a stiff pole. He whipped off the PJs and was astonished. She had a fully erect penis, located just above her vagina. There was no evidence of testicles. Her member was about the same length as his but thicker.

"But how?" he asked incredulously. "That wasn't there when I left!"

"I know. According to the doctor, it was a result of the hormone based diet therapy I'm on. A form of testosterone is part of the mix. I did ... what you do and I made it come. It came a lot, more than you even."

"Is it ... is it like mine? Where are your balls? How do you even make any?"

"I don't know how it works as it's all new to me too. I guess they are inside me, protected somehow. I even tried my come. It tasted a bit different but it looks the same", she answered.

"Go ahead, touch it." Her words were an invitation but the tone was almost a challenge, like a command or a dare. If asked, she would have said she felt powerful, like she imagined a man must feel when sexually excited with a woman before him. She also felt physically stronger than before, a strength she was willing to use to get her way, she realized.

He hesitated. Seeing his hesitation, she said: "Look I've touched yours and done all the things you've asked in the past; now it's your turn." He touched and felt another erect cock for the first time in his life. It felt silky soft and hard all at the same time. He was confused. He had never desired a man, being fully heterosexual but this was a woman. Not just any woman but his wife!

"Now stroke it, just like you like me to do." He moved his hand up and down the shaft, causing her to moan in ecstasy.

Then she said the words she had been waiting to say all day: "Use your mouth". Still he hesitated. Feeling frustrated and not wanting to wait any longer, she pinched his nose, forcing him to breathe through his mouth. Then she put her other hand on the back of his head and guided him to her groin. She pushed down a little more and she was inside his mouth. She let go of his nose and gently manoeuvred his head down, then up her penis. He took the hint and started doing it on his own.

"Ooh lovely!", she sighed as his head bobbed up and down her now slick cock. "I never realized how nice this must feel for you."

She paused for a minute and then said: "I think ... I think that I will come in your mouth." She paused and then said, "There's more, my love. I want you to swallow my come."

He stopped, lifted his head from her cock and replied, "But we don't know what's in your come! "I really don't think I ... Mmmph!"

She didn't let him finish. She placed both her hands on his head and forced her cock back into his mouth. She held him steady while she started thrusting in and out of his now straining mouth.

"You look so pretty in your nightie and matching panties; just like a girl! And like a girl, you need to learn how to suck cock!" The hormones coursing through her had made her aggressive and selfish for her own pleasure. She loved the sensations and wanted more.

He struggled but she had him held tightly in a position that gave her all the strength. Soon his struggles subsided and he started once again to suck.

"There, that's a good girl." She thought about what she just called him and smiled. It seemed fitting, somehow. After a few minutes her breathing quickened and she exclaimed, "Oh, oh, I'm going to come!"

With those words still echoing in her mind, she held his head firmly in place, gave one last shove and filled his mouth with wave after wave of hot sticky fluid. He tried to hold it in place but there was too much. He tried to let it drool out the sides of his over stretched mouth but her cock was too big. He had no choice: he swallowed.
