Living under the same roof makes the temptation unbearable. He has watched his straight stepbrother walk around shirtless, work out in the garage, emerge from steamy showers with a towel barely covering that perfect ass. Tonight, with parents away and inhibitions lowered by a few drinks, the gay stepbrother finally makes his move.
It starts with casual touches that become less casual. A hand on the thigh during a movie. Fingers tracing up the arm. The straight stepbrother tenses but doesn’t pull away — and that tiny permission opens the floodgates. Within minutes, they are kissing with an intensity that shocks them both, hands exploring forbidden territory as months of tension detonate.
The seduction is masterful. The experienced stepbrother takes his time, starting with a blowjob so good it makes the straight boy’s toes curl and his back arch off the couch. When he whispers the suggestion of going further, the straight stepbrother hesitates for only a heartbeat before nodding. The raw penetration that follows changes everything — the straight boy moans louder than expected, grips harder than expected, and cums harder than he ever has with any woman. By the end of the night, the converted stepbrother is begging for round two, his old identity shed like an outgrown skin.
