Cum in Lilly while Beth cums in my ass

Though I may or may not be interested in having Beth cum in my ass after fucking me, I don’t want Lilly to have to do anything more for Beth just because of me. Plus, it seems that Lilly really wants me to cum in her as she lied to me about being on birth control.

“I’ll do Lilly while you do me in the ass.” I respond. Beth then looks at me with an odd expression and smiles before saying, “Oh, really? I didn’t know you would pick that choice, but this is going to be so much fun for me and hopefully you both enjoy it as well. Let’s get Lilly in the right spot and we can start this little threesome right.” She then motions for Lilly to get back on top of me and Lilly starts to straddle me, but Beth stops her. “Since, I’m going to be doing Alex in the ass and not yours then I want to see your face as you ride him and he cums inside you. Plus, I want you to watch me fuck your man and see it when I fill his cute little ass full of cum. It’s something I had changed so that I could cum just like any guy.”

Lilly shrugs and turns to face Beth. “Okay, I’ll do as you ask.” She lowers herself down onto my dick while facing towards Beth. I feel the warmth of her pussy again as I watch Lilly’s ass lower onto my stomach. I’m however unable to see what Beth is doing, but I do feel something cool and wet be applied to my butt hole as a finger slides in and out a few times. This isn’t so bad after all. In fact I think I can... oh, shit! That just then was not a finger. Though Beth’s penis didn’t look very big, I can feel all of it in my ass now.

Beth adjusts herself inside of me and moans, “That’s nice and tight. Your ass feels good, Alex. It may not take as long as I thought before I’m filling you up.” Lilly however hasn’t started moving yet as I can tell she is too focused on watching Beth. I can feel what she is watching as Beth starts to move in and out of my ass slowly at first.

Beth smirks at Lilly, “Do you like what you see? I’m glad you’re watching but you may want to get started on your part or I may just do your pussy as well anyway.” Lilly moans a little before responding, “Yes, of course.” She then starts to slowly rise on my dick before going back down as she starts to try and build some type of rhythm with Beth. After a few minutes of Beth doing my ass and Lilly riding my dick they find a rhythm. When Beth pulls out Lilly goes down and when Lilly goes up Beth goes in. I’m either deep inside Lilly or Beth is deep inside me. The feeling of being fucked in the ass is strange while at the same time being inside of Lilly’s pussy feels so good. It’s rather confusing for me. The two however are getting rather good at keeping things together and they start to speed things along. Lilly moaning each time she takes me deep. Beth moaning each time she thrust into my ass. While this is going on, I’m groaning both with giving it to Lilly and receiving it from Beth. We seem to keep this up for quite some time before I feel the urge to cum.

Lilly starts to pick up the pace. “I’m going to cum soon!”, moans Lilly right before I hear Beth moaning, “Me too! How about you Alex?” This moaning and pleasure is just too much. “I’m almost there!”, I groan out as I try my best to make this last.

It’s then that I feel it. Beth is cumming in my ass and I can feel each throb of her penis as she pumps her cum into my ass. The feeling for some reason causes me to cum. I start to spurt inside of Lilly and she slams down on me as soon as I start shooting. I can feel it entering her womb. She in turn starts to shake and moan loudly as it appears she is having an orgasm. I see Beth then grab Lilly and start to make out with her as Beth pumps her load into me and Lilly shakes on top. When we all stop cumming that is when Beth lets Lilly go and she rolls off of me and lies next to me on the bed. I can see Lilly's juices coating my body as I feel the cum starting to leak out of my butt. I'm sure Lilly is just as messy, but it seems Beth isn't going to stay messy for long as she's next to Lilly's side of the bed getting her dick cleaned off by Lilly's mouth.

After Lilly finishes licking and sucking off and out whatever is left from Beth, she looks at both of us as she starts to get dressed and smiles. “That was an amazing fuck. You two were great. Though it’s late and I need to go. I had no idea we were going like that for so long. By the way, if you’re brother ever gives you trouble then you should know that we have been having sex for a while. I wouldn’t stay too long though as I’m not sure when your parents might be back. Alex, if they do come back soon, I’m not sure they will be happy to see you next to their cum stained daughter.” She finishes getting dressed and leaves the room.

It looks like I’ll need to get Lilly to untie me or try to figure something else out to keep from getting caught.
