Nina once had it all, an exciting life jet-setting around the globe as a travel writer, until pregnancy ended her career. Eighteen years later, Nina's college-bound daughter Lexi finds herself in love, while Nina sits at home alone. When Lexi brings her new boyfriend, Xander, around for dinner, Nina's passion begins to stir for the rough mechanic and his charming smile. Sweet Sinner delivers more of that honest passion and sincere sex that the studio is famous for in this 6th volume of My Daughter's Boyfriend. Written and directed by Nica Noelle.
