[Ohsaka Minami] Cumming Together with Mom♪ (Web Comic Toutetsu Vol. 97) [menospeaknihongo]

A doting mother's nap on the couch turns into a hands-on anatomy lesson when her bespectacled son can't stop staring at her exposed chest, and she decides that anything worth teaching, she'll teach with her own body. Her huge, soft tits and hairy pussy overwhelm his virgin stamina as she coaches his fingers deeper—then lets him take her properly from behind—climaxing over and over while moaning that he's hitting exactly the right spot. By the epilogue he's smugly declaring himself a family man with no patience for AI girlfriends, earning an admirer's offer to come over and fuck her sister instead.
