[Yuhi] Drink and swallow (COMIC Grape Vol. 91) [Sonarin迫]

When Shogo's passive father brings home a new bride—Nagisa, a soft, full-figured divorcee whose heavy bust strains at every top she owns—the young man can't bring himself to call her 'Mom,' no matter how warmly she dotes on him. One drunken evening and an uncontrollable hard-on change everything, and Nagisa pulls her flustered stepson close, promising it will be their secret before begging him to finish deep inside her on a 'safe day.' What unfolds is a sweat-slicked affair of bouncing breasts, trembling climaxes, and relentless rounds as the busty milf and her new stepson drown in a pleasure their family must never discover.
