[Edogawa Koubou] The Hot Summer Day I Lost My Virginity While Sinking Into the Voluptuous Body of a Oba-san

A sweltering summer afternoon leaves a young boy drenched and helpless beneath a voluptuous older woman who coos that she likes it hot as she presses deep tongue-filled kisses on him and works his shaft with slick, sweat-glazed hands. Once she's coaxed him past his first overwhelming climax, she straddles him with shameless abandon, teasing that the best thing about a virgin is how selfish he is, before taping him up, blindfolding him, and buzzing a toy against herself while using his body as her personal onahole. It all builds to a full-color cowgirl finale where she rides him through ahegao-faced orgasms, milking every last drop as he whimpers that he can't take anymore.
