Under the confines of her belt and dress, Joan's Dick quivered with need. Each move brought a delightful jolt to her core. Now, with Henry close, all the suggestive part of her mind was screaming was to either grind her dick off him, pull it out and wank it, or to bend him over and fuck him; all three making it obviously plain that she had a dick. She needed to tell him before he found out another way.
"Honey, I have something else to show you. Another change..."
She saw his eyes go wide. A flash of fear. 'Fuck', she thought. He does know the implication of too many changes. That his wife can grow a dick. Suddenly she didn't feel so confident in showing Henry. What if he rejected her? What if their dynamic changed forever? Cowardice grew, but she couldn't exactly pull back. She had to show him something. Her hooves of course.
Henry mouthed a silent "What is it?" at Joan. She bit her lip, hesitating for a moment.
"Okay, I'll show you, but please don't be mad that I masturbated. I'm not proud of it." She lied, and she knew it, her body had loved that session, and though she was a little ashamed, she knew that deep down, she had enjoyed it immensely.
Moving past a tense Henry, she sat down on the bed. Bending over she went to unbuckle her shoes, as she did her pudgy needy cock poked hard into her belly pudge, smearing and sliming it even more with pre-cum. Her kegels clenched, giving her a wonderful feeling inside. God she wanted more; really really wanted more. Bobbing her upper body twice to loosen buckles, the dick poked again into the soft warm flesh. It made Joan think of what it would be like to sink it into something else warm and inviting.
She didn't want the feeling to end. Twice more she bobbed, penis poking her belly without her doing anything to her boots. Only the shuffling of Henry snapped her out of it long enough to gather the willpower to straighten up. That in itself was a seriously dangerous action. The feeling of penis stretching almost brought her to orgasm right then and there. Only a tight clench and the last of her remaining willpower stopped her from cumming as she rose.
Sticking her leg out she offered it to Henry. "Please don't be mad, I'm really not proud of it!". She lied again, this time something clicked, deep within her. She was proud in a way. This was exciting. This was the most exciting, kinky thing she had ever done. Growing up, conservative, with no personal freedoms, she had no outlets but to rail and hate her parent, to rebel, to buck their expectations. And this. This would be the ultimate fuck you to them. She was lying on a bed, with the man she loved, showing her changed body, as her penis strained with release under her bed. Wouldn't her bible-bashing, homophobic parents not spin in their graves at that. Time to enjoy this.
She shivered as he reached out, hands slowly wrapping around the boot and softly pulling the supple leather back. The soft feeling of the leather slipping down her exposed leg and the mental release was enough. Joan began to cum. Ass clenching as her penis throbbed underneath her belt.
As her pink skin gave way to black hard keratin Henry gasped, Joan now in the thralls of orgasm shot her first rope as he did. She could feel the warm, slimy, sticky material coat the inside of her dress, smearing her stomach. Looking down she could see him staring at her foot, running his hands over them. He was busy, she could enjoy a smile. Her face beamed, a happy tear trailing from her eye as her twitching penis emptied it's load all over her stomach, locking in her scrotum forever.
Joan was just about done, when she saw Henry look up, she straightened her face as best she could.
Henry, seeing his wife with a very, very red face, and a trail of a tear down the side of her face assumed that she had been crying. Not wanting her to feel ashamed he brought his hand to his mouth. Thought out the sentence carefully and then spoke.
"It's okay Joan. I think these kind of look cute too. They're just hooves. It's not any serious change, like growing a penis or anything..."
Joan's stomach sank deep deep down on hearing that. Henry for his part thought he had just reminded and scared her that it was a possibility. Again choosing his words very, very carefully he added. "Honey, I'm sure it will not happen. I know you are strong enough to avoid this."
How was she going to tell him that not only was she not strong enough to avoid it, and already had a cock and balls, but that in the process of doing it had enjoyed it immensely, and if truth be told, wasn't averse to doing it again.
"I ummm..." She paused, acutely aware that the cum on her belly was cooling and seeping through her dress, it would show soon.
"Thank you, but I think I need a moment. I feel dirty hearing this". She hopped up off the bed, pushing past Henry. She grabbed an identical dress from the closet on the way and quickly made her way to the bathroom.
She closed the door behind her, locking and bolting it. Now safe she pulled at the shoulder straps of the dress, unbuckled her belt and watched as everything fell, peeling off at the stomach where her cum had splattered, finally revealing her drooping, cum smeared cock and balls.
