The next day, I met Hilda in the kitchen for a late breakfast. She told me dad was still asleep, probably hungover.
"But you know what works to remedy a bad hangover?"
I shook my head and had another bite of my sandwich. "Water?"
"And a nice, long blowjob," she giggled. "Since he missed his chance with Susan yesterday, I thought I'd better do my best to make up for it today."
"You're a great wife."
"The best, aren't I?"
We ate in silence for a minute. My morning wood was surprisingly hard, considering the extravaganza with Susan and Hilda the night before. With Hilda wanting to focus on dad, I didn't say anything about my own needs.
"You know," Hilda started and struggled to find the right words. "Sometimes, when I try to cheer him up, we play a little game called 'free use'."
I knew that genre of porn, I thought.
"Only you've never been home when we've played it, of course."
"I think I know what it is," I replied.
"Uh huh. And would you be okay with that? If we played it while you're at home, I mean?"
"I could leave you alone for the day..."
"Oh no, you don't have to do that. As long as you're okay with a bit more public show of affection. The last thing I want is to kick you out of the house. In that case, I'd rather figure something else out instead."
"Alright, go for it. I don't mind."
An hour later, I was relaxing in the sun on the patio, enjoying a good book and a nice glass of lemonade while trying to stay out of the way of my parents game. Dad walked out, wearing a robe and a carrying a large cup of coffee. He sat down on the sunbed next to mine and I put the book down.
"Hilda told me about last night, with Susan," he said. "Well done!"
He extended his fist and I bumped it. It was a bit weird to get that compliment from dad, but it was probably the only sane way to treat our relationship moving forward.
"Did Hilda mention anything about a what's going on today?" dad asked and sipped his coffee.
"Yeah, she mentioned the free use game..."
"And you know what that is?"
"Yeah, I've seen it on some websites. Didn't know people actually played it, though."
"Sometimes," dad nodded. "We do a lot of role playing and that's one of her favorites."
"Really? She had me believe that it was mostly for your benefit."
"Huh. Well, I like it, but it's definitely more her thing. I'm more of a bondage guy, to be honest."
Remembering how he'd tied up Hilda to the bed a couple of times, I nodded.
"Anyway," he continued. "You're okay with it?"
"Yeah, sure. I'll try to stay out of your way."
"No need. If you don't mind, I don't mind."
He drank what was left of his coffee and started to stand up but sat back down again.
"Do you want in on it?"
"What?" I asked stupidly.
"The game. I'll let Hilda know if you want in on it too."
"Sure," I replied casually, since that was the first answer that popped up in my mind.
"Great!" He stood up again. "I'll go find her. She woke me up with a blowjob, but I didn't finish."
Dad disappeared inside the house and I was left with my own thoughts. If my understanding of free use was correct, I could just walked up to Hilda and stick my cock in her mouth whenever I felt like it. Or in her pussy. Or even ass, maybe. I decided to read a bit more, letting dad and Hilda do their thing before I ventured inside the house again. I heard some moans from inside and figured dad was finding his wife very useful, indeed.
Dad had mom bent over the kitchen table, fucking her nice and slow from behind. They were both naked and she gave me the horniest look when I walked in. My cock turned hard in an instant. Dad stopped for a second when he saw me.
"Hey, son," he smiled with a drop of sweat clinging to his eyebrow.
"Hey, dad," I smiled back. "Seems like you've cured that hangover."
"Yeah, this is great!"
I put my dirty glass in the dishwasher, and dad started up his engine again, making Hilda moan loudly. I was about to leave then dad stopped completely. He seemed worried and glanced at the clock on the wall.
"Shit! I need to get dressed for an online business meeting."
He pulled out and casually walked out of the kitchen without saying anything more. Hilda was still in position, bent over the table, and did I detect a slight wiggle of her ass? I didn't hesitate for a second. I walked up to her, pulled my dick out and slid the tip up and down her wet slit before sliding inside her. She was incredibly wet and felt great around me.
I realized it was the first time I entered her pussy and paused for a moment, just taking it in. She flexed her muscles around me, milking my thick shaft.
"Go ahead," she said softly, probably thinking I hesitated to continue and needed some encouragement. "Use me."
I pulled back almost all the way out of her before slamming into her hard and deep.
"FUCK!" she screamed.
That's hot, I thought, and repeated the process.
"FUCK!" she screamed again.
I started fucking her hard and deep, speeding up agonizingly slow. She clenched hard around me after only a minute or two, having a short but powerful orgasm. I kept going, not caring about her, focusing on my own pleasure.
I didn't last long either, emptying myself deep inside her a couple of minutes later. Trying to play the game, I just pulled out and left after I had finished. I left her panting, bent over the table with a slowly closing, cum-dripping pussy. I tucked my dick back in my shorts and headed for the gym, needing to clear my head. This was all going really fast. Hilda was a completely different woman than the stepmom I had known most of my life. And to be completely honest, I absolutely loved it.
I did an almost two hour long work out before heading to the shower on the bottom floor. I passed dad's home office and his door was open. He was standing at his adjustable desk, talking to the computer screen in some sort of virtual meeting. He had a white shirt on, which would be all that could be seen by the other meeting participants, I guessed, but nothing else. Under the desk, Hilda was on her knees giving him a slow blowjob. What a nice job perk, I thought.
I took a long shower, got dressed in some fresh clothes and decided to give Cassandra a call before making lunch. That's the least I could do, since my parents so graciously invited me to their game.
"Yeah-llo?" the slightly familiar voice at the other and answered.
"Hi, this is Nick, from the other day. You gave me your card when I was in the store..."
