After our first anal experience, Valentina —my sister— and I agreed we should apologize to my cousin Ronald. Before I had fucked her ass, I had found her having sex with Ron in our bathroom, and I had overreacted, so I felt bad and thought I needed to talk to Ronald.

I called my cousin and told him I was sorry. I also told him we wanted to invite him to come on Friday night and have dinner with us. He said it was fine and agreed to come and visit us.

On Friday, Ronnie arrived at 6 pm. We hugged, and I apologized again. He said everything was fine. We sat in the living room and talked for a while, and some minutes later, Valentina showed up. She looked gorgeous. She was wearing a red top that made her black bra visible as it wasn’t big enough to cover her huge tits. Ron and I looked at her and couldn’t do anything else than say how cute she looked.

We ordered some pizza and drank some beers while we listened to music. Ron looked at Valentina all the time, and I guessed, deep inside, he wanted to fuck her again. At some moments during the night, she sat down next to him, and I could see how both acted playfully, touching each other’s arms, or placing their hands on their thighs. I knew something big was going to take place that night.

By 11 pm, we were a little bit tipsy, and then Valentina suddenly changed the subject.

“So, are you guys okay now?” she asked.

We said everything was fine. She smiled sweetly. What came next was nothing I was expecting to happen.

“So, bro, if I ask you to let me suck Ron’s dick right now, would you let me do it?” Valentina asked.

I was speechless. I had already left the bathroom situation behind, and here she was messing with Ron again. However, I guess, because of the alcohol, and because I felt tempted to see what she was capable of, I said it would be okay.

Valentina approached Ron slowly, dropped to her knees, and started massaging his cock. Soon, the bulge underneath his pants turned into a huge mass. Valentina unbuttoned and unzipped his pants and pulled them off to reveal his big cock.

My sister grabbed Ron’s cock, stroked it, and put it in her mouth. I sat there, witnessing how she gave head to my cousin. I felt an erection and wished she could suck my cock too.

After two minutes, Valentina told me to sit next to Ron. I obeyed while she stood up and removed her clothes. She looked gorgeous.

She demanded that I take off my clothes and told Ron to take off his T-shirt. We satisfied the queen’s demands.

Valentina kneeled down and grabbed our cocks. She stroked them for a while complimenting them for being big. She played with them for a minute or so.

“I would like to taste both cocks, is that okay?” she asked.

We booth nodded, and so, Valentina told us to stand up. We obeyed her command, and she began sucking our cocks. One by one, she would put them into her mouth and taste them.

She looked sexier than ever. Ronald and I took turns touching her tits and playing with her nipples.

After a couple of minutes, Ronald told her to sit on the couch. She did, and he kneeled on the carpet. He spread her legs and began fingering her. I placed my right knee on the couch and got my cock close to her head. Valentina looked at me, smiled, grabbed my dick, and started sucking it.

Ronald alternated between fingering her and licking her pussy. In all cases, Valentina moaned intensely, and I enjoyed seeing how horny she was.

“I want to fuck you hard,” said Ron after two minutes.

“Fuck me, please, cuz,” Valentina replied.

Ronald caressed my sister’s legs, grabbed her hips, and made her lie on all fours while she kept my dick inside my mouth. He positioned his body behind her, stroked his immense cock, and penetrated her. She screamed.

Ronald thrust while her big tits bounced aesthetically. Valentina kept sucking my dick as she held my shaft tightly. I just adored the view. My sister looked so sexy, so slutty that I could hardly wait for my turn to fuck her.

Ronald banged her really well. He was a complete fuck machine, and Valentina couldn’t stop moaning. He fucked her hard and squeezed her big tits while he licked her back and neck.

After some minutes, I asked Ron if we could exchange roles. He smiled and said, “Of course, cuz.”

Valentina turned her body. Her head was now facing my cousin’s cock, and her ass was facing my dick. Valentina grabbed Ron’s snake again while I was focusing on my target. I fingered Valentina’s pussy, which was super wet, and then I penetrated her.

It felt so good to fuck her this time. It was so different. I didn’t care my cousin had discovered our little secret. I was happy to see we could enjoy this all together. I thrust slowly initially, but little by little, I began to increase the pace.

Now I fucked her harder and harder, and Valentina moaned more frenetically as my cousin banged her mouth. I grabbed one of her tits, and squeezed it, and that was the moment when I couldn’t hold it anymore. I came inside her pussy as I shouted in ecstasy.

“I need to change positions,” said Valentina.

She let her back lay on the sofa, her head close to my dick, while Ronald spread her legs and penetrated her again. This time my cousin pushed harder, and Valentina could not help screaming loudly.

As Ron increased the pace, Valentina got hold of my cock, which, in no time, became erect again. She pressed it strongly while Ron’s groans intensified. He thrust a couple more times, and then, he screamed wildly. He closed his eyes and groaned one more time. He had come inside my sister as well.

Ron touched Valentina’s tits and squeezed them, and once he recovered his breath, he let his dick out of her pussy. He placed the tip of his cock on Valentina’s clit and began rubbing it intensely. Soon, Valentina’s screamed intensified, and by the way she pressed my cock, I knew she was about to come.

Valentina screamed while her thighs contracted. Her hips moved on the sofa from side to side until she had to hold Ron’s hand to ask him to stop.

We rested for a while. Ron sat on the sofa, while Valentina lay there ecstatic. I kneeled on the carpet and kissed her face and tits while she recovered.

Later, we went to the shower, and we fucked her again. She was just irresistible.

After the shower, Ron asked if he could stay with us as he was a little drunk to drive, and we agreed to put him up for the night.

We went to bed all together, and we had sex again. The same happened in the morning. In this occasion, while Valentina was riding Ron’s cock, I couldn’t resist anymore, so I approached her ass, fingered it for a couple of seconds, and made my way inside her anus.

Valentina screamed. I guess it was a mixture of pleasure and pain, but she let me in anyways, and as the seconds passed by, she felt more comfortable and ended up enjoying this double penetration. I guess Valentina had come to enjoy having anal sex.

By the time, Ron said goodbye, it was already noon. Not only had we made amends, but we had gotten to have a good time together.

Little did I know this was going to be the first time I would share my sister with other people. For some reason, our sex explorations were going to expand and reach other limits.
