Give her large breasts

You meet Keyleth’s eyes and grip her hair harshly in one hand, yanking her head back so you can plant a long sloppy kiss against her protesting closed mouth. Her lips dry and cracked against your own.

As she protests against you forcing your tongue into her mouth, the Reality Marble pulses softly in your hand from where you sent a tendril of your willpower into the powerful magical artefact. The change is immediate and Keyleth tears her head away frantically, shrieking in denial as her modest breasts start swelling. Tearing through the chest wrap and sitting high and firm against her chest, a beautiful pair of HH breasts now sit resting against her chest. Her nipples are still small and pink, looking very pretty and ready to be tormented.

Looking down you admire the new mounds that have pushed you back half a step from Keyleth’s suspended form.

“Hmm, a good start. Bimbo sized tits for Tal’dorai’s newest bimbo.”
