Their Virgin Valentine by Elisa Leigh

When their best friend was killed in action, Ryan Sloan and Javier Perez promised to always take care of his little sister. They didn’t know that promise would mean saving Sophia from her abusive father, retiring from the marines, opening their own security company, and falling madly in love with her. When they find out she’s broken their only rule and has accepted a date for Valentine’s Day they lose their minds. They’re done holding back. They are going to make sure Sophia knows whom she belongs to.
