Futaba had been having a blast with the transformation serums but something was on her mind. She wanted to get the attention of Akira Kurusu. She couldn’t think of what she could do to grab Akira’s attention when she heard audio come through the bug she had planted at Leblanc. “Hey kid, you going to the clinic again? Could you drop this off to the doc for me?” She hear Sojiro say.
Something clicked in Futaba’s head. Maybe Akira was into goths. While the doctor was more of a punk girl, it was worth a try. Futaba ducked out of her house and went to a nearby store that sold transformation serums. She went up to the clerk and asked “Hello, do you guys sell anything goth related?” She asked.
“The only goth thing we have in stock right now is the ‘Big Titty Goth GF’ transformation. It’s a special version that will change your clothes as well.” The clerk said, taking her to where it was. It was a spray can that was a bit pricier than the normal serums but it was for the changing clothes perk as well. She bought it and went on her way, not to her house but the attic of the cafe Leblanc. Once there, she took the can out of the bag and took of her beloved jacket, dousing herself with the spray to begin her change.
Her orange hair started to turn jet black, leaving only a little bit of orange at the tips. Futaba then felt a sharp poke on her nose, pulling out her phone showed that a small piercing had been put into her nose and her lips started to turn black as lipstick applied itself. Her clothes began to change as well, her short sleeves detached from her shirt and crawled down her arms. The sleeves wrapped around Futaba’s hands, becoming fingerless gloves while black nail polish covered her fingernails. As spiked bands adorned her wrist, Futaba’s shirt began to change as well. It moved up her body and a collar wrapped around Futaba’s neck to secure itself, turning black and had netting to cover her chest.
Futaba felt a heat start rising in her chest, she slid her new shirt up to uncover her breasts and just in time. Futaba felt the sharp poke of a piercing not once but four times. She looked at her chest to find that her nipples had been pierced, two piercings on sides of her nipples on each breast. Futaba’s heart began to beat, the beat sounding so loud to her. With each beat, her chest began to rise. They swelled and swelled soon growing past Ann’s bust and Makoto’s. When the beating stopped, her breasts had reached the size of basket balls.
Futaba’s lower have began to change, starting with her clothes. Her pants turned back and started to crawl up and wrap around her upper legs, it continued her her body and covered her midriff and left space where her shirt could come down. Her shoes turned black with purple lacing and began to snake up her legs, reaching past her knees becoming thigh high boots. Futaba physical changes continued as her hips started to get bigger. Her thighs and ass started swelling as well while a purple tattoo of a heart with a skull inside with wings appeared just above her boots. When her thighs stopped swelling, her changes were completed. Futaba got on the mattress that Akira used in the attic and waited for him to return.
