Long ago, I boldly promised to marry all four of my childhood friends. Now I am a twenty-year-old shut-in who has lost touch with them and feels like a complete failure. On my twentieth birthday, the friends who moved far away suddenly return, now beautiful adult women. They ask whether I remember our childhood promise and throw their arms around me. From that day on, all four gather at my house and compete for my cock, beginning a wild harem newlywed life filled with creampies.
