Grab her and put the collar around her neck
From Create Your Own Story
You stand up and walk over to Emily. She smiles as you approach.
Moving with the speed of a striking snake, you wrap one arm around her waist and pull her body against yours while you snag the collar with your free hand. Before Emily can process what's happening, you've locked the collar around her neck and rolled your bodies onto the bed.
"What--" Emily starts to say. You cut her off by planting your lips against hers and giving her a deep tongue-kiss. She responds with passion, locking her arms around you and spreading her legs as she pulls you on top of her. Her pussy is leaking nectar and her nipples are stiff points against your chest.
You break the kiss for air. "You want my body, you little minx?" you grin. "You got it." You thrust deeply into her. Emily moans and wraps her legs around your hips. Her box tightens around you with every stroke, as if she's trying to milk the cum out of your balls.
"Harder!" Emily pants. "Deeper! Pound me like you mean it!"
"You asked for it," you hiss. You piston your hips as fast as you can move. Emily immediately goes into a series of powerful orgasms. Her body writhes beneath you and her legs grip your hips so tightly you wonder if she'll cut you in half. Her hands claw at your back as she runs them up and down, and you're certain her lust is leaving blood trails. You wonder why you don't see smoke coming from her groin as she slams her body into yours to meet you. Then you lose all coherent thought as your sexual instincts take over. You ravish Emily's body [or is it the other way around?] until you finally fire jet after jet of sperm deep into her overheated love tunnel.
When you regain control of yourself and your higher brain functions begin to return, you manage to unlock the collar before collapsing on the bed next to Emily. You don't ever recall being so tired in your life.
"Aw, poor baby," Emily murmurs. "Did I wear you out? We'll need to work on your stamina." She kisses your neck lovingly. You shiver slightly. Emily rises from the bed and returns a moment later with two glasses, handing you one. It takes every ounce of your remaining energy to sit up so you can drink from it. "Here," she grins. "This'll restore your electrolytes."
After you swallow the liquid, you drop onto the bed and into a doze. When you awaken, it's been an hour. Emily's soft caresses on your face alert you to her presence.
"Wow," you groan. "You're..."
"Your new girlfriend," she husks. "Don't worry, love. I'll take good care of you."
