When Samuel's wife Kim told him about a big conference she was thinking about going to, he encouraged her like he always did. Her job was important, he said as he egged her on, and she needed to get out there and meet the right people. He'd be fine alone by himself for the weekend.
As soon as she was gone Samuel's heart began to race. He knew exactly how he'd be spending his weekend. His secret hobby that had practically grown into an addiction. He went up to his sock drawer and fished around until he found a tiny box on the bottom. It was a box for his most recent cell phone, but that wasn't what was in it, that was just a camoflage. He slid the box open and picked out one of the pink pills stashed inside. He popped it into his mouth and swallowed eagerly, then hastily stripped and retreated to the couch to watch.
His skin scrawled and he lost almost all body hair as the hair on his head grew long. Then his nipples became puffy, then bulged outwards, drooping and forming into a splendid pair of breasts. Lastly, his dick was rock hard, but as he watched it diminished to a pathetic size as his balls retreated and he felt a slight pinch between his legs and then a flush of hot, wet heat deep inside him. When it was all done he smiled and laughed in a sweet voice. He make a smoking hot babe.
But that wasn't all he was planning for this weekend. He'd been a woman many times before now, and enjoyed every minute of using his fingers to get himself off, but this time he'd decided to get a little wilder. He returned to the closet and pulled out a large unopened box. He took it to the living room and set it out, unable to keep from smirking at it as he set it up. He'd read reviews on different sex toys for women and there seemed to be a consensus that a sybian was the most intense of all of them. He couldn't believe he'd bought one. He'd kept it hidden for weeks, dreaming about it. Him and Kim's anniversary was coming up, so if she'd found it he had a lie prepared about it being a surprise for her.
Unable to resist a moment longer, Samuel lowered his burning wet snatch on to it, gasping as he felt it's girth stretch him.
Then he turned it on and saw stars. Loud, carnal moaning filled his ears and he couldn't believe it was him making those sounds. He couldn't stop himself. His fingers were nothing compared to this and he bucked his hips, closing his eyes and almost screaming as he felt himself drawing close to an incredible orgasm already.
Then he heard the door open. His eyes flew opened and he saw his wife standing there, watching him. He yelped and jumped off the machine and tried to cover himself. The sex machine which continued to buzz loudly with unspent pleasure between them as he struggled to make eye contact with his wife. How was he going to explain who he wa-
"So this is what you get up to when I'm not here Samuel." Kim said with a curious expression on her face, "Yes I know that's you. I know all about the pills you keep in your sock drawer. It was a hell of a surprise to find them, and I was pretty annoyed about it at first, but then I thought, 'why should he be the one who gets all the fun?'"
Samuel wasn't sure what his wife meant, but then he saw her pull a tiny blue pill out of her pocket. She popped it in her mouth and swallowed. She stripped as the changed washed over her, growing taller and more muscular. More hairy. By the time she got her pants off she already had a small dick and balls which rapidly inflated to an impressive set.
Now fully male, Kim walked over to Samuel and lifted him up by the wrist. Samuel marvelled at how much taller his wife was than him now. How much stronger. At first he was too bewildered by being caught and his wife's reaction to speak.
"Kim, let's talk about this." He said as Kim pulled him into the bedroom. She pushed him down onto the bed. Only then did Samuel realize she had a massive erection. A rush of excitement and fear gripped Samuel as he realized what she intended. He'd never- "I'm not sure I'm-"
"You're my bitch now. And my bitch is ready for me." Kim said, rolling Samuel over and holding him in place
"Oh god-" Samuel gasped in surprise and pleasure as she plunged her dick into him.
"Oh god, oh god!" Samuel continued to mutter as Kim began to thrust in and out of him. If his fingers had felt good and the sybian had felt incredible, this felt amaze-balls! He couldn't escape, he couldn't control it, he could only stay there and feel the incredible ecstacy his wife reaped across his soft new body.
"Oh god fuck me! Fuck me, YES!" Samuel didn't just want it, he needed it. He needed this more than he'd ever needed anything. Sex had never felt so good. He'd never felt so complete. His whole life was nothing compared to this moment.
"Deeper! MORE!" Samuel cried. Kim smiled and repositioned her husband, pushing him onto his back, his feet behind his head. She knew she didn't need to hold him down anymore. From that angle she could pound much harder, and much faster.
Samuel's world was nothing but an earthquake of pleasure as was pounded and came in a squeal of inhuman noises. Kim herself wasn't far behind. She pulled out and blew her load all across Samuel, marking him as hers in a way that she found was incredibly satisfying.
"That was... incredible." Samuel mewled.
"Good because those were X-tra Strength pills. We're staying this way for a month." Kim had planned this as revenge for Samuel keeping secrets from her, forcing him to confront/embrace his pink pilled-side in front of her. Now she was genuinely looking forward to the time though.
"A month?" Samuel cooed in surprise. His stared down at the cum on his chest, hefting the weight of a boob in one hand while the other went south and stroked his still tingling and oh-so-sensitive pussy.
He was pretty sure a month wasn't going to be long enough.
