Narrowing the gap

It's extremely dark in the room, the only real source of light is the TV screen, and Cindy's phone turning on when it gets a notification, she eventually turns it off, trying to avoid any interruptions on our strange, sexual, hang out.

Every now and then Maria tries to get closer to me, which is strange considering we're all already pretty much as close as we can get, she shuffles her torso over to mine and rests her head on my shoulder, turning on her side and resting her left arm on my chest, Cindy notices this and decides to do the same, resting her head on my shoulder and hugging into my chest.

Halfway through the movie, a sex scene appears, I accidentally move my arm inbetween Maria's legs, when I try to remove it, her legs grasp into it, I look over to her face as a reaction, she smiles and plants a small supple kiss on my lips, wrapping her tongue around mine, Cindy seems to be oblivious to this, Maria, pulling away from our intimate kiss, but still looking into my eyes, starts to grind her pussy on my arm, she starts to make moaning faces, letting out small weeps when the movie got loud, I start to get a boner, just as this happens Cindy catches a glimpse of Maria and I, she grins and turns my head towards her, she pecks a few times on my lips, slowly but surely, then massages down my chest and into my briefs grasping my cock, I moan, she grabs my other arm with her other hand, and guides it down and into her panties, I start to rub her pussy slowly, she moans, now that there's two girls using me as a human sex toy, I seem obligated to ignore the movie and really get into this, I tilt my head back and close my eyes, feeling my left arm starting to get wet, and my cock starting to get harder.
