A Stepsibling’s Jealousy Homewrecking My Stepbro

My stepbrother and his girlfriend have been making out on the couch right next to me for weeks, and I’m sick of it! I’ve been wearing more provocative outfits at every opportunity to try to get my stepbrother’s attention, and tonight when I got home from the club, he was in the living room and his gf was in the bedroom. What else could I do but shoot my shot?
