Sisters Boy friend and her friend Shikha

It was a typical Friday night at Rina's apartment. I, Amit, her older brother, was hanging out with her and her boyfriend, Veer. Rina was looking as stunning as ever, with her toned body and big C-size boobs that were barely contained by her tight top. She had on a micro skirt that showed off her amazing ass and flat belly. Veer was a lucky guy.

As the night went on, Rina and Veer started getting more and more into each other. They were sitting close together on the couch, their bodies pressed up against each other. I couldn't help but watch as they started making out, their hands exploring each other's bodies.

Rina stood up and pulled off her top, revealing her hard nipples and poky boobs. Veer's hands immediately went to her tits, squeezing and massaging them. Rina let out a moan as Veer's mouth found her nipple, his tongue swirling around it.

Rina started grinding her hips against Veer, her skirt riding up to reveal her pink panties. Veer's hand snaked down to her pussy, rubbing it through the fabric. Rina let out a gasp as Veer slipped a finger under her panties, finding her wet and ready.

Veer started fingering Rina, her moans getting louder and louder. Rina reached down and started stroking Veer's dick through his pants, feeling it grow hard in her hand. Veer stood up and pulled off his pants, revealing his hard cock.

Rina dropped to her knees and took Veer's dick in her mouth, sucking and stroking it. Veer let out a groan as Rina's mouth worked its magic. Veer pulled Rina to her feet and bent her over the couch, pulling down her panties.

Veer entered Rina from behind, thrusting deep inside her. Rina let out a loud moan as Veer started fucking her, his balls slapping against her ass. Rina reached down and started rubbing her clit, her orgasm building.

Veer started fucking Rina harder and faster, his dick hitting her G-spot. Rina let out a scream as she came, her pussy clenching around Veer's dick. Veer followed soon after, pulling out and cumming all over Rina's ass.

I watched the whole thing, my dick hard in my pants. I couldn't believe what I had just seen. I quickly grabbed my phone and started taking pictures and videos, capturing the moment for posterity.

Later, when Rina and Veer were finished and cleaning up, I approached Rina. "Hey Rina," I said, "I have something to show you."

I pulled out my phone and showed her the pictures and videos I had taken. Rina's eyes widened as she saw herself and Veer in all their naked glory.

"I can't believe you took pictures and videos of us," Rina said, a blush spreading across her cheeks.

"I know, I'm sorry," I said, "but I couldn't help myself. You two are so hot together."

Rina looked at me for a moment, then smiled. "Well, since you have all this evidence, I guess you're going to have to help me with something."

"What's that?" I asked.

"I want you to help you to get Shikha for you," Rina said, referring to her best friend. "I know she's been eyeing you for a while now, and I think you two would be perfect together."

I couldn't believe what I was hearing. Rina was offering to help me get with her best friend. I couldn't wait to see where this was going.

"Okay, I'm in," I said, grinning. "Let's do this."

And that's how it all started. Rina and I teamed up to get Sapna for me, and it was one of the hottest experiences of my life. But that's a story for another time.
