Two MILFs get involved with the wrong 18 year olds.
I slide them in and out a couple of times, checking your wetness. "Very good. Feels like someone's ready."
I take my fingers out and slide the vibrator inside of you, spinning it slightly as I push it in and out of your wet pussy. With the belt still in your mouth, you make muffled little moans. A few moments later I quickly remove the vibrator from sloppy little cunt and in one quick motion, slide it in your asshole.
Without meaning to, you let out a quiet squeal and the belt drops from your mouth. You lower your head in an attempt to get it back but before you can, I give your ass a severe, loud smack.
"Leave that where it is. We'll deal with it shortly," I say while slowly moving the vibrator in and out of your ass. "Focus on what I'm doing for now. I'm going to leave this vibrator inside of you. It's very important that you keep your asshole relaxed or it will pop out. And we don't want that, correct?"
"No," you respond, between quick, heavy sighs.
I run the vibrator all the way inside of you, let it go, and walk around you so that I'm standing by your face. The belt is lying there, between your hands. You carefully glance up at me with a look that someone else might confuse for pained, but I know better.
I crouch down, grab the belt with my right hand and slowly stroke myself with my left for a few moments as I watch you clearly focusing on not constricting your asshole and keeping the vibrator where it is.
"As for this belt," I say, holding on to the leather end and letting the buckle drop from my hand, "we're going to use it as a makeshift choke collar and I'm going to use it as I fuck your from behind."
Before the end of the sentence leaves my mouth, I notice that the vibrator is quickly getting pushed out of your asshole. It drops to the ground.
I look down at you and see equal parts fear, excitement, and confusion. "I'm sorry," you whimper. Without saying a word, I grab you by your hair and pull you up so that you're on your knees, back straight, and eyes forward. I walk behind you and pick up the vibrator.
"Open your mouth and turn your head to the left." You do and the vibrator, still on, goes in your mouth. "Now face forward again." You do.
I take the belt and run the tail end of it through the buckle, leaving a lot of slack in the middle for your head and neck. I put the loop over your head and then down around your neck, gently pulling on it to tighten it around your throat, like a reverse tie.
You drop back down, vibrator working in your mouth and belt around your neck, reminding me again of a puppy. "Good girl."
I slide my cock inside of you from behind and to my pleasant surprise, I'm met by what's probably the wettest pussy I've ever felt. "I see that someone's enjoying their first lesson." I hear you mumble what sounds like a 'yes' through the noise of the vibrator, so I pull the leash back, choking you ever so slightly, and say, "Spit that thing out; I want to hear all of your noises now."
You spit the vibrator out, gasping for air and moaning, "...again...". I pull the leash back, tighter this time, and hold it, continuing to rapidly work my hips as I do, fucking you with the full length of my cock, my balls slapping against your body. After about 12 seconds, I hear you struggling to breath, and after an additional 2 seconds, I give the leash some slack.
I'm breathing hard and between breaths I say, "I want you to try and last as long as you think you can this time. When you need slack, grab my balls with your left hand, got it?"
I give the belt a sharp tug, pulling your head back a bit, a rapid breath escaping your lips.
