Sharing the Stepsister: A Forbidden Halloween Short

by Isla Storme

Cole Maddox has wanted his stepsister since the night he met her. Four years of hallways, holidays, and doing nothing about it.

Then the parents leave town, the old house starts its usual noises, and Tessa ends up in his lap during a horror movie she picked as a joke. He doesn’t move her. His brothers notice. He still doesn’t stop.

What follows is not a love story. Cole decides she is his, lets Bennett and Reid borrow her for one night, and takes her back when he’s done. No courtship. No speeches about feelings. No one learns a lesson.

This is a short, unrealistic, all-spice erotica. Almost no plot. No character development. If you want a relationship arc, this is not that book.

Told in Cole’s first person.

Hot stuff

Just my kind of book. Lots of cum swallowing and a good ass fuck. Brothers learning to share with a triple penetration.

Just filthy!

Nothing but raunch! Plots be damned! It was still a fun read! Hard to find relevance in this kind of novel, but that’s ok too!
