The nephew, who suddenly visits his beautiful aunt known for her fair complexion and clear atmosphere, earnestly requests her to be a model for a painting. Despite her confusion and hesitation at this abrupt proposal, the forceful nephew convinces her, leading her to expose her naked body. Excited by her large breasts and sensually sweaty, voluptuous figure, the nephew eagerly fondles her ample chest and devours her exposed, hairless vulva, forcing her to take his erect penis into her mouth. The aunt, feeling pleasure from their lewd acts, mounts his penis herself, shaking her large breasts and engaging in intense intercourse, delighting in the ecstasy.
