[Done] True Feelings, Pure Feelings (Towako Kyuu) {Mistvern + Bigk40k}

Shirone, a fluffy fox spirit who doted on her human ward as his grandmother, has grown hopelessly lazy around the house—until the young man she raised returns home and finds his soft, plump-bottomed granny sprawled out and begging to be spoiled. She takes him for a ride, breathless at how the boy she once cradled in one arm now grips her petite body with broad, grown hands that could easily crush her. Beneath the heat lies her confession that she seduced him out of fear he'd stop needing her, and his tender vow that she is his one and only precious granny promises a bond—and a household—together forever.
