It's time for your pet...

"Is that how we ask for things?" You reach up to grip the scruff of her neck, pulling her down to her knees in front of you. She grunts as her knees hit the dirt.
"I'm sorry... p..please...will you come punish me properly for my mistake?" You unzip your shorts, and your dick springs up.
"Start apologizing, Kayla." She needs no second prompting, immediately slathering you in spit and taking it as far down as she can manage.
"I was all....nngn....ready to treat you like a good girl and at the first opportunity, you forget your fucking place." You keep your hand on her head, not letting her get more than a few inches away from full throating.

"That's good, pet. That's good apologizing...." you pop your hips upward, abusing her throat so that she gags, spitting up more and more on your cock. The firelight plays beautifully over the lewd spectacle.
"Unnnnnhhh... Unnnnhhh..." she's moaning now, and it rumbles against your cock, lodged deep in her throat as it is. You grab her hair and pull her up roughly.
"Good girl... now come with me." You stand up, not bothering to tuck your cock away, and you march her by the neck over to the hot tub enclosure, but instead of going into the tub, you snag the restraining cords for the shades. One at a time you secure her wrists, one to each of the support beams of the roof. She's now tied, arms spread, and **** up onto tiptoe for comfort.
"Oh...baby..." she pants. You untie her bikini bottoms.
"Spread those legs, slut. Assume the position." She whimpers as she attempt to follow your orders. The sagging that comes from spreading her legs puts more pressure on her shoulders, and she groans. You use her bikini bottoms to tie her ankle to the slats of the enclosure at the bottom, and remove her top to do the same to the other ankle. She's now restrained at every appendage, **** to keep her ass raised to avoid pain in her shoulders.
"Ahhh..." she squirms a little, and you grip her throat from behind.
"Are you complaining, little girl?" You squeeze, and her eyes bulge as she shakes her head furiously.
"Good... Now... don't go anywhere, I'll be right back."
She squirms and whimpers as you walk away. You head over to the storage shed, where pool supplies and such are kept. There also happens to be a... special box in there.
You grab your "supplies" and you spend a few minutes just watching her squirms and whine. She's so **** right now. You return with the box and plant it next to her, opening it to pull out some... equipment.
"So, my Kayla. Are you done being a bad girl, tonight? Bad girls get punished harshly, but good girls get treats." As you say "bad girls" you set a thin leather strap on the railing in front of her, then a long, narrow buttplug, then a leash and choker. When you say "treats" you set a vibe with a remote control in front of her, and a ball gag.
