[Crimson] Senpai no Kareshi ni Osowarete... Suzumine Saika Hen

Suzumine Saika has everything — the student council presidency, a swim club she carried to nationals, and a bombshell body that makes her a living goddess — but her untouchable status left her with zero experience in love or intimacy, and one man is about to exploit all of it. That man is her senpai's boyfriend, who corners her with a soothing 'it's fine, don't go home yet' while his hands claim her huge breasts, then bends her over despite her 'I don't want this' and works her toward a bed where her body starts betraying her with moans she can't swallow. As she comes apart in tears under his grip, a door slides open somewhere behind them — and whoever walks in next might catch the school's perfect idol in the most compromising moment of her life.
