Mark took a deep breath, wiping sweat from his brow as he walked hand-in-hand with his girlfriend, Jenna. He wanted to enjoy his last week as a man before a condition known as "transience" changed him into a woman forever. As of now, he was a man of average build, with pale skin and short-cut brown hair.

They were enjoying a Japanese cultural festival when he suddenly gasped and doubled over. His insides churned as he began to rapidly lose height. " F-- Fuck! It-- it started early!" He groaned, his voice heightening in pitch.

Jenna's eyes widened; they were in public, so it wasn't an ideal time for transience. "Do we have time to get you home?" She asked with concern.

"N-- No!" Mark choked as people started to look and whisper. He felt Jenna take his hand and lead him through the crowd as his chest ballooned into C-cup breasts. He wasn't ready to change yet! He was supposed to have a week. To make things worse, pressure started to expand within his body, right below his navel. His hips popped outward while his waist pulled in. Immediately after, tingly pulses wracked his crotch.

The onlookers gasped as one of them yelled that someone was undergoing rapid transience.

Mark felt his cock receding as tears fell from his face. He didn't even get to use it one last time. "C-- Come back..." She pleaded, grasping at her crotch while Jenna offered reassurances and pulled her toward the car.

With every step, her chest bounced more, straining against the fabric of her shirt. Her hips and ass stretched the fabric of her pants, causing the material to hug her new vulva as the warm, pink folds finished forming. "I-- I don't want to change yet!" She groaned as her face softened, dark hair growing to her back. A tail sprouted at the base of her spine while her ears migrated upward, taking on a feline appearance. "Ahhhh!" She moaned as her newly formed pussy pulsed and writhed, oozing sticky fluid.

By the time Jenna got Mark into the passenger seat, she was a completely different person. She turned the air on and looked in awe, blinking in disbelief. "Woah-- you're the cutest cat girl I've ever seen," she said with red cheeks.

Mark blushed amidst her panting and trembling. "D-- Don't say that..." She whined and huffed, putting her hands over her face.

The next day, Jenna put Mary in front of the mirror. "Ta-dah!!! Look how cute you are!" She chimed with a wide smile.

Mary stared at her reflection in disbelief. "This-- is me?" She wore her hair in twin tails with red bows and had blue overall shorts over a well-fitted red blouse top. Thigh-highs finished off the ensemble perfectly. Her feminine sex twitched and grew hot as she inspected herself. 'Maybe things could have been worse...'
