Her flexible hips swayed as her erotic flesh jiggled right before my eyes—Yuki, my father's new wife. Completely absorbed in her provocative twerking practice, she was lost in the rhythm. I couldn't help but secretly peek at her rehearsal, until eventually she caught me. "Mou, if you were watching, you should've said something! Well? So, am I shaking my hips nicely?" she teased, provocatively thrusting her soft, mature ass right in front of my face. Overwhelmed by the seduction of her massive, irresistible buttocks, I completely lost control.
