Another visit

My girlfriend was silent about everything that happened. By that I mean she didn't respond to any messages for a few days.

But she was busy apparently. At least that is what her message said. "Sorry I was busy at my new job, It takes up a lot of time and leaves me exhausted so I didn't have a lot of time to message you back."

But speaking to her about it I found out she was enjoying her job despite how demanding it was. Was it a coincidence that she got time off the same day my sister returned? I certainly didn't think of that coincidence at the time. At least not until my sister was off work one day, she rarely got time off as her job was to be mom's cum dump, as she called it anyways. In reality she was a receptionist for the hotel my mom managed.

She kicked her legs up on the table as she sat on the couch. Her legs were spread and she basically only wore panties. "What are you doing here? Don't you have work?" Her state of dress has been normal for me since she was first fucked by mom so despite her rather attractive body I was used to it.

She looked up at me then dismissed me turning back to her phone as she spoke. "Oh, mom found a new hole to stretch with her cock." I was used to my sisters crude way of speaking. Then she did a few taps on her phone, my own phone buzzed with a message. "See, check out the total slut she found."

I had no words to say at the sight of my mom in her work suit with an arm around Sarah, my girlfriend. It would have been fine for a photo... If Sarahs clothes were decent. Her skirt was too short and my mom was pulling down her shirt to pinch the modest breasts.

As I stared at it my sister spoke. "Apparently she even has a boyfriend, but there's no way that will stay. She's totally worshiping our mom's cock every day I'm not."

Her words caused me to feel worry. I hadn't seen Sarah since our date but apparently she has been spending all this time with my mom...

"See look at this, she's totally a slut." She sat up showing me her phone screen. On it was a picture of Sarah hugging a cock that touched her chin.... How did that manage fit in her? I remembered the picture on my mom's computer of her and distinctly don't remember seeing even a sliver of the cock.

I barely got out a strained word. "Oh..." Then my sister resumed being lazy laying back and kicking up her feet again.

"Just don't tell mom I told you, she said that I couldn't tell you for some reason." Of course she would... She was fucking my girlfriend after all.

But looking at my phone I read the last message from Sarah. "I'm coming over for dinner tonight. See you then." So I waved at my sister shooing her off the couch.

"Come on get up get dressed. My girlfriend is coming over today." There was nothing I could do about it, my sister would figure out what was going on the moment she saw her.

She looked surprised at me. "You are inviting someone over? A girl no less? Especially one you have feelings for?" I saw her grin as she jumped to probably accurate conclusions. "You do know mom is going to try and get them alone right?"

I could only blush and look away as she called me out. "Just get up and get dressed at least." She stood giving me a pat on the shoulder and whispered to me. "Don't worry, I wont tell mom your desire at letting her at them."

Her teasing smile shattered into wide eyed shock as Sarah wrapped me in a hug when she came in. I could not bring myself to look at her and avoided all eye contact... Which wasn't hard as I knew just minutes before Sarah arrived here my mom was inside her. How did I know? The way she walked and her satisfied expression.

My mom arrived just after she did and grabbed my sister. There was no guessing what the two were doing. When my sister returned it was with the same walk and expression as Sarah which further confirmed it.

But my sister rounded on me and **** me to look at her. She whispered into my ear. "You knew?! You're letting mom just fuck her? I wasn't kidding that she was going to break up with her boyfriend you know. I know from experience, there was absolutely nothing satisfying about my ex after our mom did her thing."

A could only shrug before I responded. "I guess its a bit too late for that now..."

She sighed stepping back and I realized that when my sister started talking to me Sarah was missing... Along with my mom. Just to prove this my sister pointed at the kitchen door. "Right now they are fucking in the kitchen, I'm supposed to keep you occupied until dinner." My sisters gaze changed to disgust when I immediately took a step for the door and she stopped me.

"What?! You want this?! I cant believe you! Just don't get caught, then mom will take advantage of how pathetic you are." Despite her words she followed behind me also peaking on the two. To ensure we didn't get caught she was pressing into me as we looked through the cracked door.
