Stepbrother’s Rules by Renee Rose

LuAnn’s had a crush on her older, rebellious stepbrother since the year he lived with them—his last year of high school. Now, four weeks before graduating from Sarah Wharton Women’s College, she’s been kicked out for having boys in her dormitory, and he’s the one who shows up to collect her. With her parents away in Europe, he brings her to his place, because leaving a young woman unchaperoned isn’t done in 1957.

Brad makes it clear she is not to emulate the wild behavior of his youth, and he starts things out with a long, bare-bottomed punishment. Soon, though, he discovers his stepsister is all grown up, and having her under his authority makes her a temptation too delicious to resist. Before long, he’s strayed way past what is acceptable, turning her into his little girl and bringing her to the peaks of pleasure during her numerous punishments. LuAnn brings out the dominant side of him, but with it comes the desire to take care of her and nurture the sweet innocence she’s been trying to cover up. He wants her for keeps, which means risking their parents’ disapproval and leaving his rebellious side behind forever.
