新・したがる兄嫁 ふしだらな関係
Synopsis
Megumi’s every thought pulses with desire as she pours her loyalty—and her body—into supporting her struggling actor husband, Kazuo. Their modest home brims with unspoken yearning, each tender kiss at night a reminder of passion simmering beneath routine. When Kazuo’s dazzling star brother Ryōji arrives, Megumi feels his evil gaze tracing her curves, his breath hot at her ear. Left alone together, Ryōji’s hand drifts along Megumi’s arm, igniting a wildfire of forbidden heat that surges through her veins. Their stolen glances become urgent kisses; his fingers map the soft valley between her breasts as her sighs echo in the silent room. Caught in the throes of decadent temptation, Megumi teeters on the edge of a choice that could shatter her vows—and unleash every secret craving she’s ever held and become a pure sexual beast.
