I walked into the kitchen and there she was, Mom bent over the counter in nothing but an old apron, her thick ass cheeks spread wide as she wiped down the surface. "Morning, baby," she said without looking back, pushing her hips out a little more. That was the signal. Free use meant whenever I wanted it, I took it. I dropped my shorts, spit on my cock, and shoved it straight into her asshole in one hard thrust. She grunted but kept wiping, her ring gripping me tight while I started pounding.
Aunty walked in a minute later, coffee mug in hand, and just smirked. "Already at it? Save some for me." Mom's ass was hot and slick around my dick, the kind of greedy hole that had been trained for years. I grabbed her hips and slammed deeper, watching her cheeks ripple with every thrust. "Fuck, Mom, this ass is mine today," I growled. She moaned low and pushed back, taking every inch.
Aunty set her mug down and peeled off her robe. She was older than Mom, curvier, with an even bigger ass that jiggled when she moved. She came up behind me, pressing her tits to my back while her hand reached around to stroke my balls. "Give it to her good. Then it's my turn." I kept railing Mom's asshole, the wet sounds filling the kitchen, her hole making filthy squelches every time I pulled out and drove back in. Mom's voice was rough. "Harder, son. Wreck Mommy's ass."
I did. I fucked her until her legs shook and she came with a sharp cry, her asshole pulsing around my cock. I didn't stop. Free use rules meant I finished when I wanted. I pulled out, turned, and grabbed Aunty by the waist, spinning her to face the table. She bent over without a word, reaching back to spread her cheeks and show me her already lubed hole. "Been waiting for this since last night," she said. I lined up and sank into her ass just as deep as I'd been in Mom's.
Aunty's ass was tighter, hotter, and she knew how to work it, rolling her hips to milk me. Mom came over and knelt beside us, reaching under to rub Aunty's clit while I pounded.
"Look at you taking my boy's cock in your ass," Mom teased. Aunty laughed breathlessly. "Jealous? You already got your turn." I switched between them for the next hour, moving from one stretched hole to the other, using their asses like they were made for it. Mom on all fours on the floor, Aunty riding me reverse while I sat on the chair, both of them moaning and begging for more cum in their guts.
By the time I finally unloaded, it was deep in Aunty's ass while Mom licked my balls. I pulled out and watched my load leak out of her, then Mom cleaned it up with her tongue before I pushed back into Mom's ass for round two. The whole morning was nothing but raw, messy anal, their bodies free for me to use however I wanted. They both came again before I was done, holes red and gaping, exactly the way free use days were supposed to end.
