My sister

I turn to look over at the pool and no one was there. The two girls must have gotten out and I didn't notice. I look around the yard and see nobody, maybe no one is watching. I turn back to my Chloe and Melissa is right there.

"Jesus Christ!" You scared me. I jump back a little bit.

"Don't worry brother I just couldn't help myself after watching you two." She sits on Chloe's face and bends down to suck on my cock. I can hear Chloe sucking on Melissa's pussy and she definitely stuck a finger or two in her pussy as well.

I get really self conscience. "Where is Cassidy?" It would be so weird if she say this scene, I'm still not used to the **** being okay thing.

Melissa takes my cock out of her mouth. "Oh she say how you two were and she thought the three of us should have some time together." She puts my cock back into her mouth and resumes giving me a great blowjob.

Chloe slides down to be able to speak. "Well how nice of her," Chloe get up. "I'm going to see if she's okay, You two have your fun." She walks back into the house.

Melissa takes off her bikini and bends over in front of me. "Stick it in my pussy and maybe if you treat me well I'll let you fuck my ass."

I stick my dick into her pussy, slowly going in and out at first and then start speeding up. "This feels so good." I say

"Yeah it does." She replies. She brings her hand on her clit and start rubbing it. I put my thumb on her asshole and start rubbing it, she moans in response to it. I use some of her pussy juices on my thumb for lube, I press my thumb into her asshole. Her asshole slowly takes it in until it just pops in.

I hear someone cough for attention. I turn my head and it's Cassidy and Chloe both completely naked, but Cassidy is wearing a strap on dark purple dildo that looks about the same size on my cock.

I joke. "That better not be for me." While I continue to fuck both holes of Melissa.

Neither of them say anything. Cassidy just walks towards us two. Melisssa makes me go on my back and she climbs on me in the cowgirl position and slides my cock back in her. Cassidy walks around to me and french kisses me for a few minutes. Cassidy walks over to Melissa's ass and slides the strap on into Melissa's ass.

"Oh fuck!" Melissa screams in ecstasy. "I feel so full. Mom we should have done this sooner."

I turn to Chloe and she is lying on the patio stones with three fingers in and out of her pussy and two fingers on her other hand deep in her ass.

Melissa cries out. "I'm fucking cumming!!!!" She squirts all over Cassidy and I.

When Melissa started to squirt I came deep inside her. Cassidy pulls the dildo out of Melissa's ass and sucks the cum out of her pussy. "Fuck your cum is so good." Cassidy moans.

As Melissa and I lie there dead tired from all the sex. We both get into a spoon position and lie there together and watch Cassidy walk over to Chloe and stick the dildo into Chloe's ass.

"Oh fuck!" Chloe moans.

It didn't take long for Chloe to cum. After she does we all just lie down and recover for the next few minutes.
