All good things must end.

As the day wore on, I stopped feeling like I was in paradise. Sure, I was surrounded by two hotties, but I couldn't help remembering that they were totally inaccessible to me--my stepsisters, for god’s sake! I'd been fighting an erection for hours with no gratification in sight, except maybe my own hand later that night.

Not only that, but painting was harder work than I'd thought, especially since I was the one who had to move all the furniture around so we could get to the walls--“the perks of being a big strong man,” the girls told me, giggling. It was exhausting, and it seemed like a stupid waste of our time. I had no idea why the hell Marisa and Jessica had fought to begin with, but hadn’t they gotten over it yet? The fight had been months ago and I couldn’t understand why they were refusing to share a room and making me do all of this extra work.

Between the boner I couldn’t do anything about and the work that I resented, I was feeling pretty frustrated. But I wasn’t the only one--Jessie always had a shorter temper than her sister, and her irritable mood was clear from her body language, which made her no fun to be around. I started focusing a little more on the way Jessie’s tits were bouncing and rippling as she moved. The two bright spots in a dreary afternoon, I decided.

Until out of nowhere, I wound up in trouble.

“Hey Mike, can you at least close your mouth while you’re staring at my boobs?” Jessie snapped at me suddenly. “Bad enough I have to put up with other creeps drooling all over my chest, I don’t need that from a perverted stepbrother too. He’s been leering at me all day,” she added for her sister’s benefit. Marisa rolled her eyes at me, which I knew meant she thought I was being dumb.
