Note: This story contains some bisexual elements, including male/male spanking.
I've come to think of Stanley and Marilyn as authority figures, and so does my girlfriend, Dalia. We're all friends, and double date often. It's just that nowadays, we know who's in charge.
It wasn't always that way. Early in the summer, I had a different understanding. I'd noticed that Stan had a certain way of dealing with Marilyn, frequently giving her a pat on the butt if she'd made some wisecrack or acted petulantly. I liked that, including the fact that he did it in front of me and Dalia. I started doing the same with Dalia now and then, including in front of them. It was very pleasing to think of the two of us guys having a bit of an upper hand over the girls.
One night, we'd just finished dinner at Stan's beach house. I'd been eyeing the ladies in their bikinis all day, and now they were in short skirts. For some reason, though, they were both sitting next to Stan on the sofa, one on each side, pressing against his legs. I was jealous. Why was my girlfriend, as well as his own, giving Stanley so much attention? I sat in an armchair grumpily, and more so when he expansively put his arms around both ladies' shoulders. He was wearing jeans. I was in sweatpants, which didn't well conceal that I was starting to get hard.
"Dalia's quite into you, Stan," I muttered. We were always making jokes about getting involved with each other's partners. In fact, I was the one who usually brought up the subject. But nothing had ever happened. Still, I was feeling increasingly horny as well as jealous. Especially, after Stanley put on a smug smile and said, "Not much you can do about that, Roy." The ladies both looked at me, and then smirkingly pressed their legs even closer against Stan's.
Feeling my face flush a little, and maybe having finished my beer a bit too fast, I shot back an uninhibited answer: "I can spank both of them if I have to."
It was a throwaway line. I thought there'd be a few giggles and then we'd move on. But Marilyn looked at me with a raised eyebrow. "Really?" she said. "Somebody might do some spanking in this household, but it sure isn't going to be you, Roy." With that, she shifted her hand from Stan's thigh up around his crotch, which was now bulging against his jeans. Dalia gave me a smirk, and then, to my surprise, also put a hand up against Stan's bulge. "Whoa," I said.
"Well, it looks like both ladies have chosen who they're serving tonight," Stan said in a friendly tone. "Whom," I said irritably, correcting his grammar. Then, while keeping his left arm around Marilyn's shoulders, Stan lifted his right arm from Dalia's shoulder and instead placed it on Dalia's hand, pressing that more fully against his crotch. Dalia giggled, and I could see she was stroking him under his hand. "Uh, Dalia?" I said, my voice trailing off. She didn't look at me, instead focusing on giving strokes through Stan's jeans.
I sat there quietly for a moment, stewing with jealousy, but also fascinated. How far was this going to go? And where did I want it to go? My cock was straining against my sweatpants now, as Marilyn noticed. "No complaining, Roy," she said briskly. "I see you're enjoying the show."
