When a young man finally gets invited to his girlfriend's house for a much-needed overnight stay—a rare luxury in their relationship—his anticipation is high. Just as he dreams of intimate nights with Mami (the younger girl), she reveals her older sister: Yume. Initially surprised that Mami wasn't an only child! Upon arrival at the home base of romance and relaxation,
Yume immediately charms him with her vibrant personality and suggestive questions. The tension escalates dramatically when she brazenly exposes her stunning bust and perfect curves right in front of him while Mami watches on. Unable to look away from this goddess figure,
the protagonist finds himself completely captivated by his girlfriend's beautiful sibling.
As he chats with Mami in their room, Yume orchestrates a perfect distraction, coaxing Mami out of sight so she can focus all her seductive energy on him. The attraction proves irresistible; he quickly dons a condom and plunges into passionate sex with the older sister inside her own bedroom. Midway through their intense coupling, Yume halts the action and strips away the protection. Despite the inherent risk, the sheer ecstasy of raw, unprotected penetration sends him over the edge.
The ensuing session is pure primal lust. He drives himself insane with pleasure, repeatedly flooding his hot hole with semen until he's utterly spent. Over the course of their two-day stay, this greedy lover manages to deliver countless powerful cumshots deep within Yume’s womb—all while his girlfriend remains just feet away, witnessing every intensely intimate moment.
