[Takei Tsukasa] Uchi no MEIKKO TACHI GA Sukebe ni natta ken. Ch 1 (COMIC Magnum Vol. 120)

A bespectacled uncle returns home to discover his beloved nieces Inori and Mayuri have developed an unusually passionate affection for him, with his prized train umeboshi sparking memories of their shared childhood. Their playful teasing escalates quickly as the busty sisters strip down and take turns smothering his face between their enormous breasts, begging him to make love to them in ways their "squeezing" little hearts can no longer contain. The frantic trio eventually tumble into bed together, the girls giggling about virginity and fantasies of threesomes while happily mounting their overwhelmed Oji-san.
