Professor, Make Me Stop Growing! Vol. 1 - Professor, Make Me Stop Growing!, #1

Lily, a 23 y.o. chemistry student, has unknowingly ingested a fertility and femininity enhancer. She's about to go from a tall, mature-looking young lady to a dainty sweet young-looking thing who literally has way too much to carry around! Neither her, nor her professor on whom she has a crush, know what a "big" change is about to take place, binding their lives together. An hourglass, breast and butt expansion story.
In future parts, pregnancy and lactation will occur. The main character has loving and helpful people by her side, but she is quite uncomfortable with her enlarged assets and this life change she fears to be permanent.
