You use it to make her cum

Once you put your weight on the bed, Adela watches your eyes move down her body.

"Spread your legs for me." You demand.

Adela does exactly that as you press the button on the wand, bringing it to life. Rather than pressing the toy to her body right away, you hold it above her head. You then wave the wand above Adela, who does her very best to hide that she craves its magic touch. To her credit, she doesn't offer a word, or even sound, of protest, but her **** eyes betray her.

With a smile, you decide to lower the wand onto her left nipple, to which she whimpers. The wand then travels to her right nipple where it stays for a few seconds. Next, you move the wand's end down to her belly button. It rests there for a second before it travels down to the red patch of hair above her craving slit. Looking into her eyes, you say "Do you want me to go lower?"

"Yes Sir." Adela replies

"Beg for it."

"Please Sir. Please put the vibrator against my pussy. Pleeease."

In reply, you move the toy right where she wants you to.

"Ahh... Thank you Sir." Adela moans.

You watch as your submissive indulges in the pleasure the vibrator is giving her, beginning with passionate cries that cause your erection to strain against your pants. Soon enough, she begins to shudder as the sensation builds, the chains of her cuffs rattling as she squirms around.

"You gonna tell me when you're close?"

"Agh... Yes Sir."

"Good girl."

You continue to watch Adela struggle underneath the vibrator. It's not long before her toes curl and her fingers ball up into fists. Then she clenches her teeth, as her body starts to shiver at the mercy of the wand. All that's left to wonder is if she'll be honest this time. The last time you did this, you denied her to put her on the edge, but maybe this time you may do something different, if she's honest."

"Are you going to cum?"

Adela nods.

"Say it."

"Ahh... I'm cumming Sirrrrr..."

"Cum for me." You state.

"Ohh... Thank you Sirrrrr." Adela throws her head back as her body quakes throughout the blissful sensation, her limbs writhing around uncontrollably. When she finally stops, you turn the wand off and put it on your nightstand. Moving on top of Adela, you look her in the eyes as she gasps for air.

"Thank you Sir." She repeats breathlessly.

"Well, you were a good girl today, and good girls get rewarded."

After leaning down and kissing her, you think of how you should reward her for her obedience, and yourself for your patience.
