After getting into college, I move out on my own and become obsessed with the plump ass of my married neighbor, Sumire, especially when she wears skin-tight jeans. One day she invites me over and searches for something on all fours, putting her ass right in front of me. Unable to resist, I pull down her pants, enter her from behind, pound her wildly, and cum inside. Overwhelmed by the first cock she has had in ages, Sumire starts thrusting her hips back on her own.
