As Jeff stared up at Jenny and marveled at how short she was, Jenny watched her boyfriend's confused face and smiled. He really was cute when he was confused. And he was even cuter now that he had boobs. Jenny turned and headed straight for the large tub and turned the faucet on full blast.
Jenny stood up and reached her hand out. "Come on, babe."
Jeff got in the tub first. She winced in anticipation of the water touching her crotch. She lowered her round butt into the warm water and...
...nothing. She looked up at Jenny in surprise. "I thought that would feel," she paused. "Different."
Jenny laughed. "What do you mean different?"
“More sensitive, I guess.”
Jenny smirked. "You thought your pussy would feel all sensitive? Oh no, sir. You are the owner of one tough little pussy there!"
Jeff blushed as she sat down in the tub. Her long hair was floating in the water around her shoulders. Her large boobs gently bobbed on the water line, floating high as if in an invisible push-up bra. Her eyes scanned both of her areola as they jumped both above and below the water. Jenny smiled at the sight.
Jeff swallowed, with difficulty, and suddenly felt very small naked. She hadn't noticed Jenny's eyes jumping across her breasts before, but she did now. Jenny was not being subtle at all. Jeff crossed her arms, covering her nipples, and looked away.
Reluctantly turning back to look at Jenny, Jeff saw the lust in her eyes. She knew the feeling well. She could only imagine how her old male body would have reacted to being in a hot tub with a naked woman.
And now HE was a naked woman! Jeff held her boobs even tighter and squeezed her legs together. She looked at Jenny's large chest and slender arms. She began to imagine the arms holding him down. She imagined that bosom pressing against her own, keeping her small, female body stuck against a mattress, ready and willing to let this woman do all sorts of things between her legs.
Jeff shook her head to dispel the notion. Why on earth did she just fantasize about that?
Jenny finally spoke. "Come on... let me see you."
Jeff looked into Jenny's eyes. She still trusted her. Sh slowly lowered her arms, allowing her breasts to sink downwards into the water. They began to float and bob along on the surface. Jenny smirked as her eyes followed their every move. Her right hand moved forward, gently grabbing one of Jeff's tits. Jeff watched it with curiosity. The sensation of having her boob grabbed was unlike anything she'd ever experienced before.
Jeff had never felt so small before. If Jenny had told her she was shrinking, she'd have believed it. But no, it was not another transformation, it was just the feeling of a woman much larger than herself using her size as an advantage to dominate her. To Jeff, this normal human interaction was as alien as magic.
Jenny squeezed the breast. "They feel so great!" she exclaimed. Jeff didn't want to admit it out loud, but she was beginning to agree. Her mouth hung open and her breathing sped up. Jenny noticed, though, and pressed forward. She brought her other hand up and, with her fingers, began to flick, pinch, and gently twist Jeff's nipples.
This time it was too much to resist, and Jeff moaned. The feminine sounds coming from her mouth shocked her, but she couldn't stop it. She transitioned from moaning right into a gentle whimper. She was not consciously aware of it, but her tightly-squeezed thighs began to loosen. Her feet spread apart as her legs began to slowly open up.
Jenny's fingers kept up their ministrations as she leaned towards Jeff's ears and whispered. "I know how you feel, babe. I know exactly what your body wants. Just let me give you what I know you need."
Jeff closed her eyes and began to nod. It was hard to form words, but she knew exactly what she wanted. Jenny took one of her hands and let it drift down Jeff's torso. Entering the water, she gently tickled her belly button as her hand sunk lower and lower. Her fingertips gently grazed Jeff's pubic mound and finally found themselves between Jeff's smooth legs. It was very strange to not feel an erection between her boyfriend's legs, Jenny thought. There sure was a lot more room to move around here now.
Jenny paused there, knowing the effect she was having. She dragged her fingers back and forth on the inside of Jeff's leg, never getting closer to the prize between them. Jeff's whimpering had gotten louder and now she was almost growling. Jenny finally felt she had suffered enough and brought her hand forward. She cupped her fingers under Jeff’s round butt and pressed her palm into her crotch. In one motion she had squished her vulva and clit into one warm, wet mass. To Jeff, this reminded him of having his cock deep-throated. It was very rare for a single motion to touch every part of her genitals at once, and Jenny had just done it with ease.
Jeff felt the water from the tub leave her pussy right as the warm wetness inside her exploded. She felt the juices leak out of her little hole and her groans turned to gasps.
"Jenny!" Her eyes shot open. "I'm going to... going to..."
Jenny smiled. "Are you about to..." she paused while simultaneously bringing her pointer finger up to Jeff's pussy. With one smooth motion she plunged it all the way inside Jeff's vagina and curled it upwards.
She finished her sentence "...cum?"
Jeff felt too many things happen all at once. Her lower lips had been spread open. Her vagina was gripping a foreign intruder, vibrating with confusion. Jenny's finger had found and was tickling Jeff’s G-spot. Her other fingers were pinching her nipple. And all the while, the heel of her palm continued to knead and press Jeff's clit in a circular motion.
Jeff's butt clenched. Her back arched. She felt sexual pleasure somewhat similar to what she'd known before, but all mixed together with the sensation of being penetrated - something she could barely comprehend. Her thighs locked and flinched and her female body unleashed an orgasm unlike any she'd ever felt as a male. She began to vibrate and squeal.
"My pussy... my... I'm... Jenny! I'm a girl! I'm a girl!" She managed to look down at her body and see her jiggling tit with Jenny's finger entering her body further down beneath the water. The sight made her think of being stabbed, and it felt scary and wrong all while her body was telling her it felt good. The incongruity was insanely strange. "I'm... a... WOMAN!" cried Jeff as her orgasm ran laps around her body.
Jeff's orgasm made her feel incredibly female. She was aware of the long hair cascading over her narrow shoulders. She flexed her toes and could somehow tell they were half the size of her old ones. She even imagined painting them red after this was over. Her butt felt huge and her waist impossibly small. As her hips shook, she realized that their new shape was designed for birthing children. Jeff could be impregnated. Jeff could become a MOTHER. The thought kept her orgasm as strong as when it started.
She threw her head back and was acutely aware of how far away the ceiling looked. She wasn't just female... she was SMALL. A tiny, helpless woman completely under the control of her larger girlfriend that was currently making her cum.
Jenny grinned. This was a lot of fun to watch. She knew exactly what Jeff was feeling and kept moving her hands to keep it going.
"I'm... I'm Josie now..." Jeff said as her orgasm waned. "I'm a girl... mmmmm... my pussy...my girlfriend loves my pussy..."
Jenny slowed her finger's movements in shock. Jeff calling herself “Josie” was unexpected. Jeff's mindset had changed very quickly. Apparently, the female orgasm was a life-changing experience. She had become very accepting of her new sex all of a sudden. Jenny was surprised, but happy. Maybe now Jeff would be open to more... experimentation.
