**Chapter 13**
“Harder, Master,” my sister’s incessant whimpers sent shivers bolting through me. *“Harder.”*
“Ava,” I groaned, feeling beads of sweat rolling down my forehead. “Stop it.”
“Not until you go hard. Just like how you fuck me in bed.” She leaned closer, licking my earlobe. “Or in the elevator an hour ago. I can still feel your cum inside me.”
“Ava.” I set the dumbbells down and turned to my sister, my cock throbbing under my shorts. “What the fuck? I thought we were trying to workout?”
She let out a cute giggle, looking absolutely ravishing in her tight sports bra and even tighter leggings, her skin slick with a light sheen of sweat. Ava shook head, her pink ponytail swaying, amusement coloring her blue eyes.
“You’re just so much fun.” She inched closer and nibbled on my ear. I inhaled her scent, groaning at how fucking good she smelled, even better when sweaty. She giggled, the girly sound turning my breaths ragged.
