One of the farm-hands stopped us with shipment forms that one of us had to sign. I took care of it, and Maxine and I continued on our way toward the stables to check on things.
By this point, it was afternoon, so the horses were out in the fields. Maxine walked ahead of me, and once we were out of sight, I couldn't help but stare at her swaying ass. She noticed, and with a coy smile, she lifted the back of her dress, and showed her bare ass so I'd know she had nothing on underneath.
Her perfect ass was welcoming, and I knew she'd intended for us to be able to fuck with ease, although I still had jeans, as well as my underwear to deal with. It was a moot point, in either case, since we could always find a hiding place for our fun.
Maxine let her dress cover her again and we both walked into the stable, where a farm-hand was working.
"Everything in order, here?" I asked.
"Like usual," he said.
"Good," I said. "Maxine and I will take care of adding the feed, you can go."
The farm-hand nodded and left the stable. Once he was far enough away, Maxine closed the outer door, and turned to look at me.
"You know, I bet we could find a good spot in here to fuck," Maxine said.
"Maxi, you know the farm-hands come and go all around this place throughout a day," I said.
"Yeah, and we just told one of them we'd feed the horses," she said. "They won't ask questions."
"Unless one of them hears you moaning," I said.
"That mean we're gonna fuck in here?" she smiled.
I paused for a moment, but gave in to her as usual. "Yes, fuck... this is a mistake, but let's do it."
She squealed in excitement, and walked over to one of the many side tables we'd built. They sat just below the waist for the average person.
"How about right here?" Maxine said.
"On the table?" I said.
"Yeah, you can bend me over it, and fuck me from behind."
I simply nodded, knowing that arguing with her about it would be pointless. She was one of those girls who would commit to an idea. Once she made her mind up, that was the final word.
I unzipped my pants and pulled them down while Maxine lifted her dress to her waist, and leaned over the table. I got right behind her, and my cock slid across her ass cheeks, as I'd intended.
"Just make sure you put it in the right hole," she teased.
"And what if I decide to put it in your ass? You're kind of in a compromised position, here Maxi," I teased back.
"As if you'd have the balls to do it," she said.
I pressed my cock right to her ass hole.
"Oh yeah?" I said.
"Don't you fucking dare," she scowled.
"Oooh, Miss Maxi only likes cock in her cunt?" I said.
"Mick, seriously, don't. I fucking mean it," she said.
"Oh but you're convinced I don't have the balls to fuck you in the ass. Why would you suddenly get serious, if you really believed that?" I continued to tease her. I pushed against her ass hole again.
"Okay! I get it. You're clearly gonna do it, so I take it back," she said.
"Say it. Say I have the balls to fuck you in the ass," I said.
"You definitely have the balls to fuck me in the ass. Happy?"
"Uh huh," I laughed.
"Can you please just shove it in my pussy, now?" she said.
"What are the magic words?" I said.
"Fuck you," she laughed.
"Close, but not quite there, sis."
"Fuck me?" she laughed again.
"That's right," I said. I pushed my hard cock inside her pussy once again, and with the thrust, she moaned. In. Out. Repeat. I bent over her while I fucked her, and kiss her upper back, just below her neck. My hands held her hips, and hers held her dress, for want of a better place for them.
The motion made the wooden table rattle and bang against the wall of the stable. It was loud, but I didn't care. I was having sex with the sexiest girl I'd ever known, and a bonus was that she was my sister.
That fact never left my mind, and it even served to turn me on more. Any doubt I'd previously had, most definitely faded away, just as I'd thought. Now it was just me, her, and the sex. Nothing else mattered.
It didn't take long for her pussy to get wet enough to make the act even noisier. The sloshing sound was obvious, and even satisfying. Erotic in its own way, especially as I could feel some of it drip to the base of my cock, and down my balls before it fell to the stone floor below.
"Ohh God," Maxine moaned.
I never let up, and by now I was rose up again and pounding into her.
"Easy Mick, if you're too rough, someone will hear us," Maxine said.
I simply ignored her warning, I knew she was enjoying herself, and so was I. Her tight pussy clenched my cock, which only made me more horny. It felt so good, feeling her pussy so tight and snug around my shaft, I couldn't help but pick up the pace.
Maxine's breathing became more labored, and so had mine. I think we both knew by now, what was about to happen. A few seconds after she moaned again, I felt my cock shooting cum inside her yet again. One... Two... Three... Four... Five. A smaller sixth shot left my cock before I pulled out and pulled my pants back up.
"That really felt good," I said with a smile.
"Yeah, it did," Maxine said. She let her dress drop again, and stood up straight.
I double-checked around the stable to make sure no-one was nearby, and we both left, after adding the feed to the mesh feeders, and hung them on hooks for when the farm-hands would bring the horses in.
Evening came quickly. At five o'clock, the farm-hands locked everything up, and went home for the day. I made dinner, with a little help from Maxine, and we sat in the living room to watch a movie. It wasn't anything sexual, just a random movie we both wanted to see.
We held hands, while cuddling on the couch. Our fingers intertwined. It was so right, so perfect. Holding the girl I loved in my arms, both of us totally naked and free. At some point, Maxine fell asleep in my arms. I watched her sleep for a while, then I too fell asleep.
The next morning, I woke up to find a blanket covering us both, and two sets of folded clothes on the floor in front of the couch. I recognized both sets; one was one of my outfits, the other was one of Maxine's. In my morning haze, I could smell bacon and eggs being cooked in the kitchen, and two people were talking quietly.
I woke up Maxine, who was just as confused as I was about what was going on. After a few minutes, we both recognized the voices, and realized what happened. It was our parents.
"Oh my god..." Maxine whispered. "They know..."
"I guess so," I whispered back.
We were mortified, both at being caught, and by the fact that they were home early, but it was done, and now we had to deal with the consequences.
We both got up and put the clothes on, and quietly entered the kitchen, fully expecting to be yelled at and lectured.
"Good morning, you two," our dad said. "Looks like you had quite the night. Have a seat, and we'll have a little chat."
We did as we were told, and mom brought us a plate of food. I couldn't help but wonder why they were both so calm. They'd clearly caught me and Maxine naked on the couch, but instead of waking us up, they put a blanket over us, brought us clothes, and were now serving us breakfast. I was positive there was a huge catch to this whole situation.
"So. How long has this been going on?" Dad asked.
"What?" I asked. I wasn't about to divulge anything they didn't already know.
