So my nerdy cousin Chie has been living here for a few weeks now, and holy shit, this is turning into the horniest household in existence. I can hear her through the wall every fucking night – that desperate little whimper she makes when she's rubbing her clit while reading her tentacle hentai. She thinks she's being quiet but her whole bed creaks when she arches her back to cum. And she's ALWAYS at it.

Meanwhile I'm in my room with my fucking massive cock in my hand, stroking one out just to relieve the tension from engineering projects and general life frustration. The other night we both came at the same time and I swear to god the house shook. Two futanari under one roof with libidos this high is a dangerous combination.

We haven't fucked yet – she's still a virgin and I'm not about to be the one to take that from my own cousin, no matter how much I'd love to bend her over and fill her tight little ass with my cum. But fuck if the tension isn't building. The way she looks at my tits sometimes... I catch her staring at my bulge in my pajamas...

This is either going to end with the best orgasm of my life or the most awkward family dinner ever. Place your bets.
