Excitement reaches its peak as the brother thrusts with wet, squelching motions in missionary position. The sister's cries of "What are you doing...!?", "That's disgusting!!", and "Don't touch me!!!" ring out realistically. She wakes up mid-act, discovering the truth. The ensuing confrontation is also recorded. Their once-close relationship shatters instantly. She refuses to accept his apologies. The brother, acting irrationally, pins her down and forces his cock into her mouth and pussy. She resists, saying "Let's kiss—" "No, gross... I used to love my big brother (crying)," but he cums inside her, and she obediently submits. Her glassy, blissed-out expression during sex heightens the story's climax. Her pink nipples erect, her ass gripped tightly during hard doggystyle. Finally, after being creampie fucked, she's left dazed and blank. The future of the brother and sister's relationship is left open-ended, inviting readers to imagine what comes next.
