Simon switched targets to the other sleeper Bryan. Seeing Jay transform into a donkey boy had aroused Simon deeply and inspired him regarding Bryan's changes.

Bryan moaned softly and rolled over in his sleep, as his body rearranged itself internally. Simon gently pulled the covers off his friend so he could observe the changes.
As he lay on his side Bryan's hips expanded and his buttocks inflated, pushing his hips skyward. His briefs stretched taught across his womanly hips before snapping. His now naked cock and balls retreated into his body, leaving behind a hairless slit.
Bryan sighed girlishly and rolled onto her back, because it for some reason she couldn't get comfy sleeping on her front. Not any more, anyway. Two ripe breasts had sprouted from her chest and were still growing. Simon's hand absent mindedly stroked his cock as he watched those orbs bloom and spill over his friend's chest. To his specification, they rounded out as massive DD cups, with quite a few more year's worth of growth to come.
And so Bryan became Bunny, a girl with a voluptuous figure developed far beyond her 13 years, with a playful attitude, a dominating sex-drive and very little willpower. What's more, she became Jay's devoted girlfriend of 6 months. All because Simon had always wanted to see a chick get it on with a donkey.
