[ROYD-301] My Fiancée’s Secret Training Sessions with My Brother-in-Law

It all started when that worthless brother-in-law moved in, turning our home into his twisted playground. Every single day, he sneaks into her room, forcing her into those depraved sessions he calls ‘training’—it’s nothing but raw, relentless breeding practice. My G-cup fiancée, Chisaki, used to be so innocent, but now she’s completely hooked on the filthy thrill of it all. I can hear her muffled moans through the walls as he takes her, her massive tits bouncing wildly with every thrust, and it’s clear she’s fallen deep into the pleasure of this infidelity sex, craving more with each secret encounter.

Her body has become his personal toy, and she’s embraced every depraved act without a shred of shame. Those huge G-cup breasts are constantly on display, squeezed and slapped during intense titty fucks that leave her gasping for air. She rides him in cowgirl, grinding down hard to milk every drop of pleasure, her face a mask of ecstasy as she betrays me right in our own bed. The creampies are a regular finale, him filling her up as she trembles in climax, lost in the taboo of it all—it’s a solowork of corruption, with her eagerly submitting to his every command, her big tits heaving with each sinful release.

Now, she’s fully under his spell, a willing participant in this cuckold nightmare. The breeding training has warped her mind, making her beg for more of his seed, her body used and marked by his dominance. I watch from the shadows, powerless, as she takes him deep, her tits jiggling with every movement, lost in the sheer depravity of their acts. This isn’t just sex; it’s a complete takeover, with Chisaki surrendering to the pleasure, her infidelity becoming a daily ritual of shame and ecstasy that consumes us both.
