The punishment continues.

You quickly head outside, to the supply shed. Five years ago, give or take, you had gotten into BDSM porn pretty intensely, and you had intended to introduce Jenna to the lifestyle at the time, but she had been hesitant, only indulging a little roleplaying with safe words, before losing interest in that idea. Now that she seems to have rediscovered a desire for this kind of play, you can finally put to use... the equipment... that acquired perhaps prematurely.
You return to the house, toting a small locked trunk. You head upstairs, and push into your bedroom with it.
"Theeeere you arrrrre....." Jenna is on the bed, just as you requested: face down, ass in the air, wiggling back and forth seductively, naked as a jaybird.
"Good girl." You set the trunk down, and unlock it. Throwing back the lid, you pull out silk cuffs, dark blue, and a set of leather ankle shackles. You also pull out a large buttplug, a leather strap, a ball gag, and a choker collar with a leash.

Jenna licks her lips as she sees you lay out your tools...
"Oh baby... when did you get all these things?"
"A long time ago. I'm glad to finally get the chance to use them..." you smile as you slide the leather strap along her ass cheek.
"Do you remember our word?"
"Of course baby." _Cease. _If her mouth was full, it was a simple "unh unh" and a shake of her head. "I won't need it..."
"Don't be afraid to use to use it, Jen, if things get too intense..." You smack her ass, medium strength, and she squeals.
"Harder, James! I've been a bad girl! Rubbing that ass against other guys, flirting with them..."
"Patience...." You begin your work: you shackle her ankles and secure them to the foot of the bed frame. Then you use the silk cuffs to secure her wrists together, running the silk between her legs to also secure to the foot of the bed frame. She is now trussed tightly, with her ass elevated and ****.
You lube up her asshole, and work the large plug inside as she moans and whines, until only the jeweled tip is visible. Then you secure the red ball gag in place, the spiked dog collar and leash, and finally, a blindfold.
"Nnnnn...." Jenna purrs against the gag, soaking it in spit.
"Are you ready for your punishment, Jenna?" You continue to call her by her name: It is too easy to depersonalize her in this type of sex play. You don't want that.
"Mmhmm...." she nods.
You start working her luscious rear with the strap. You go gently at first, building momentum, until she's whimpering and crying out against the gag with every strike. You rub her red asscheeks every so often, and take breaks to finger her dripping pussy and toy with the end of the plug.
You grip the leash end, pulling her head upward as you fuck her slowly, your hips colliding with her scorched cheeks. She moans and screams against the gag in pleasure and pain, and you make sure to keep an ear out for any sign that she needs to stop.
