Growing a Valentine's Gift for the Professor, Vol. 1 - Growing a Valentine's Gift for the Professor, #1

Biographie de Gal X. Pander

An erotica writer focusing on female breast, butt expansion, pregnancy and lactation. Each story of mine shows a 21+ y.o. college-aged woman go from tall and slim to petite and voluptuous, while winning the heart or falling in love with her middle-aged tall, svelte professor, and giving him a family at the end. My erotica contains female breast expansion, hourglass expansions, lactation and pregnancy (usually quadruplets, and usually sped up).
The female protagonist's assets reach the size of exercise balls, but do not render her immobile (at least not permanently).
