Luna expands

Luna mutters a spell under her breath and Ginny gasps in shock and distress as she feels her young lover swell even larger inside her toght little cunny. Ginny chews through her sticky bedsheets, turning her head to look back at her friend humping away at her tender backside. Luna is panting, too caught up in the deep thrusts she’s pounding into Ginny to notice or care about the dread in her eyes.

Ginny groans in pain as Luna’s cock throbs, bulging a little thicker and longer each time. Ginny’s toes curl and her eyes roll back as Luna expands deep inside her vagina, distending her soft young belly bit by bit around her growing penis.
