“What’s the string for?” Ally was eyeing everything I had laid out on the bed in preparation for making her body my dessert. “And ruin the surprise?” I cocked an eyebrow at her, predicting her reaction. “Come ooooooooonnnnn” she drawled, rolling her eyes and giving me a pouty face that she accentuated with a very obvious huff. Predictable. My amusement was evident on my face even as her face crinkled up in annoyance. “You’re the one who wanted to be my slut.” I reminded her, causing her to shoot daggers at me. “Hmph.” She declared, knowing she was trapped by her own needs. “Mmhhmm, that’s a good slut,” I chided, as i picked up the sleeping mask. “Now, let’s heighten your senses.”
“Please, sir, twist my nipples.” I faltered as my hand reached towards her pert, perfect tits. “How…” I cleared my throat as I struggled to form the rest of my sentence “how hard, my… slut?” Even as the word left my lips, it felt wrong. Seriously? I had a slut? I don’t know how I managed such a thing. I hadn’t set out with any intention even close to that. Yet, Ally had a way of taking the perversion I kept pent up in my head, and turning it into action. “As hard as you think is neccessary, sir. Hurt me as much as you need to to get off. My body belongs to you, master.” The blood froze in my veins at the title. But, my cock betrayed me by twitching – almost violently – inside the tight pussy of my girlfriend. “Master.” I was just getting used to being called “sir” and now… the silence was broken by a yelp as I was returned control of my body. Ally had gotten her wish, as I attempted to make her nipples pay for unknown transgressions. “Yesssssss, hurt me and make me yours, master.” A new chapter was opened to us that night.
I stared at the beautiful brunette currently spread eagle in my bed, her limbs restrained by soft rope knotted tightly to the bed frame. She was clad only in a sleep mask, on edge with every step I took and each touch that snaked across her light caramel flesh. “So, my slut, would you like to cum before or after we use the string?” Ally’s breathing visibly quickened at the question, even as I teased her by letting the loose end of the string send shivers across her as it barely grazed her tight waist. “Will you still hurt me, master?” I smiled as I whispered into her ear, “I suppose that depends. Have you been naughty?”
