The Unexpected ProposalGroup Sex Story 

We drove to a beautiful house in an exclusive gated community outside the city. As soon as we entered the garage, we got out of the car, and Sergio opened a door and turned on the lights.

“This can’t be real,” I exclaimed, looking at the dungeon-like room filled with various structures and devices, including a Saint Andrew’s cross, a double bench, a wooden structure with several holes that Alex called a stocks, an unusual wooden table, a horse-shaped rack, a large bed, and a shower and bathroom area. The most unsettling part was that all these structures had several rings attached to them.

I asked my brother again if Sergio was trustworthy. That display of means seemed excessive for having sex with them. My brother took my hands, looked me straight in the eyes, and assured me that he would take care of me, repeating what Sergio had said in the storage room: that we wouldn’t do anything I didn’t want to do. He also pointed out that there were no whips, flogs, or any device meant to cause pain or damage.

My knees wobbled again, this time due to the desire to surrender to them, hoping that my wish to participate in a threesome would come true. Slowly, I undressed until only the garter belt and stockings were left.

“I guess they wanted me to wear this and not take it off, like it’s part of the atmosphere,” I said, collecting my hair into a ponytail.

Both of them nodded, smiling like mischievous kids. Then I thought that I should behave like a slut, since they had dressed me like one. With this idea, I looked around, observing those structures carefully, trying to decide which one to use. Finally, I chose the double bench, approached it, knelt on the lower one, and rested my arms on the wider upper one. In this position, I called my brother with a gesture of my finger.

“Fuck me for now only in the pussy,” I said when he started undressing behind me. “I need to see if I can handle Sergio’s cock in my ass.”

My brother began to fuck me slowly, pulling his cock out almost completely every two or three penetrations. He knows how much I love feeling the head push through my tightness. Moaning in pleasure and with my eyes half-closed, I looked to my left and saw Sergio touching his crotch through his pants. I had avoided sucking their cocks before, which is expected in these situations, intending to do it while one of them was fucking me. I called him with my finger, and he approached slowly, as if he were a king and I his concubine. I gave him the satisfaction of sucking his cock, but I could only take about half of it. Finally, I limited myself to sucking it, taking advantage of the thrusts my brother was giving me.

“Take off your clothes and fuck me in the pussy,” I begged between moans. “I can’t get the idea of fucking you out of my head since we were in the storage room.”

Sergio smiled, but unexpectedly, he walked away, opened the drawer of a cabinet, and returned with several condoms in his hand.

“I think we can trust each other,” I said, frowning, looking for an explanation in his eyes.

He smiled again, leaned down, and whispered something in my ear that left me speechless:

“One day, I’ll fuck you bare, whenever you want and however you want, but only if you accept to be my girlfriend.”

What a fucking asshole he turned out to be. It was inconceivable that such an ego could fit in one person. I didn’t respond, and I watched as he put on a condom. Then he pushed my brother aside, placed the head of his cock between my pussy lips, and remained motionless. I took matters into my own hands and pushed myself back onto his cock. If I already loved it when Alex opened my pussy several times, doing it myself with Sergio’s cock was heaven. The interesting thing is that Sergio didn’t show any caprices again, he only wanted to find out how deep I could take him. It was logical considering the length of his weapon. With this information in mind, he grabbed my ass with both hands and started fucking me like a possessed man.

“I don’t understand why you’re so obsessed with me being your girlfriend,” I said, panting like a slut. “I’m much younger than you, and I’m sure many girls would accept without blinking.”

Sergio laughed and slowed down his thrusts. My brother, silent until then, converted into a mere spectator, put his cock in front of my nose and forced my lips to take it. I only limited myself to letting him fuck my mouth, concentrating solely on Sergio’s response.

“What are we supposedly looking for?” I asked, licking my brother’s cock.

Sergio stopped fucking me, leaned against my back, and whispered something in my ear that left me frozen:

“It doesn’t matter to me. I don’t judge it because it’s fucking awesome, but you fuck daily with your brother, now with me in front of him, which means you don’t want commitment, you just want to have fun, just like me. Being my girlfriend means you can fuck whoever you want, because I’m sure you’d tell me, and that’s what matters, the trust.”

After catching my breath and resting, I had a talk with Sergio about how he knew Alex and I were siblings. He confirmed that he didn’t know from Alex and I felt relieved. He simply pointed out our obvious facial similarities, something not many people notice, but mothers tend to pay more attention to details. I cleared this up and brought up Sergio’s unexpected proposal again. I approached it rationally, saying that in other circumstances, I would have accepted without hesitation. Only an idiot would reject a guy like Sergio. He’s not just attractive, but also seems genuine and confident, which I value above all. His liberal views on relationships also encouraged me to accept his proposal, but I had to do it with some indifference to hide my eagerness.
