SINN: Gluttony: Level -3

The first time Lucas chooses pain, it feels nothing like punishment.

His father has written from Bavaria with an ultimatum disguised as love: come home, leave Berlin, and pray until the son he remembers comes back. Lucas knows what it costs to live under that kind of love. He can't go back on those terms. But refusing his father's shame is easier than getting it out of his head.

In a hidden club beneath a Berlin tenement, Lucas descends to SINN's third level. There, Lennart introduces him to a carefully negotiated world of impact play. Lucas discovers the difference between pain inflicted to make him smaller and sensations he can choose, stop, and want again. The marks on his back become a private record of that difference, even as life aboveground—in the library, on the city's cold streets, on the phone with his mother—keeps testing his new confidence.

And then there's Leon.

The tattooed bartender has been Lucas's favorite reason to linger at the bar since the night they met. He can deflect almost anything with a joke, except the sight of Lucas's marked skin. For one suspended moment, Leon seems desperate to reach across the space between them. Then he pulls away, leaving Lucas with a question neither man can laugh off.

Gluttony is the book in SINN series, an emotionally charged M/M BDSM erotic series set in Berlin's secret underground. Lucas's journey into desire and self-acceptance deepens here, while his slow-burning connection with Leon remains an unfolding, series-long story. Read Limbo and Lust first.
