shrinking vial, a growth vial, and a regular human female vial. She loved the feeling of shrinking from before, and a sick, twisted dream came from it. She would grow Mary once she was outside of her, turn her back, then take the shrinking potion herself. Her only issue was getting Mary out of her, which would be easier said than done without the vials. Madison drank all of the growth vial, resting the other two vials next to the box. She felt a similar warmth as before, her whole body shaking in anticipation as she began to grow. She could feel her body stretching, being pulled in every direction by unseen forces. 3'5", 4'2", her body rose faster than it shrunk, quickly loosening its grip on Mary.
If Mary could breath a sigh of relief, she would. Her body, nearly crushed, may have felt nice, but it was also calming to know this should all be over soon. Though she was unaware of the plan, this felt like a step in the right direction. She could feel Madison stand up and she started to slide out of her. Mary slid out, falling to the floor with a slight 'thud'. Madison picked up Mary, looking extremely small in her large hand. Madison stood at least 7'5", with a properly proportioned body to match, not that Mary could see at this point. Madison had already refilled the growth vial, now dumping it down into Mary. Mary felt that sweet sensation again as she grew, her body growing longer and harder. Madison set Mary the cock down on the ground, her shaft already 3' long, and still growing steady. Madison prepared herself, drinking the shrinking vial, refilling, and drinking it again. As she started to shrink, she poured the female vial into Mary. Mary now sat at about 6' tall, slowing her growth. Madison climbed atop Mary and began to climb inside of her shaft, the process becoming easier as she shrunk down to the size of a doll. Mary felt a tugging at her skin, and a solid object groping and climbing down her insides. Her arms and legs returned as her balls moved up her shaft. Her face began to reshape, her hair growing back from her scalp. Straight and brown, it ran down her back, stopping above her tailbone. She swallowed hard, extra precum and the solid object in her throat.
"Madison?", she asked as soon as she was able, not seeing her roommate anywhere. She took a closer look at the vials, growth, which explains why she is back at her normal height, female, which explains how she is back to normal, and...shrinking. Was Madison that solid object in her? Come to think of it, it had seemed to go from the size of a fry, working on fragment. It was too late to ask her why or attempt to change her mind, Madison was too far gone. Mary picked up the vials and placed them on the table, debating on which to try next.
