Make Jane pick.

"Yes please. Do you want me to give you another blowjob while we do that?"

"Maybe later. Right now I just want to figure out what these settings do and focus on your pleasure."

"Y... you do?" Jane looks up at you in awe. "Nobody's ever done something just for my pleasure before."

She's so overcome that you have to hold her for a while until she calms down. Then you pull up the app again. "Let's see what we got here..."

The first tab you show Jane is Reports. "Well well, look at this. The hydrometer says you're already a little wet."

"Yes master," she smiles back at you. "The way you were touching me all over while you copied your notes felt lovely, and I'm excited to see what you'll do to me."

"Actually, I want you to make the first choice."

"Me?" Jane squeaks. You just switch to Zones in the app and place your phone in her hand. Jane studies her options for a while, and then daintily touches the index finger of her other hand to the 'Nipples' option.

A second later the phone drops onto her lap. "They're buzzing! Feel it!"

Showing uncharacteristic boldness, Jane takes your hands and moves them onto her chest so her hard nipples press against your palms. They are buzzing, not like a joy-buzzer but with a deeper vibration that feels like it's coming from somewhere behind them. You can feel a faint rumble shaking her breasts, but most of the vibrator's energy is focused directly into her nipples for an intense sensation.

You rub your hands in slow circles over Jane's breasts for a few minutes, kissing her neck and listening to her breathe. Then you lightly squeeze her nipples and play with them between your fingers.

Jane squeaks adorably. Your hands begin to wander, stroking her stomach and sides alternately as you always keep one of them on her breasts. On your next pass, you pick up your phone and switch to the app's main screen, where you adjust the vibe's pattern. Jane moans and leans into you as her breasts shift from a constant buzz into a slow pulse. Both your hands are on them again, kneading her flesh in time with the vibrator's pulses.

"Master," she breathes. "Will you let me suck you off now?"

You smile at her. "Of course, pet."

You sit back and start taking your shirt off while Jane turns around to unbutton your pants. When she has her mouth on you you decide to sweeten the deal for yourself and turn on 'Mouth' under Zones. Luckily the app allows you to select more than one zone at a time, so you don't have to deprive Jane of the sensations she's receiving through her breasts.

The tingle you felt this morning starts again, but this time it's affected by the same pulse pattern you set for Jane's nipples. Jane bobs her head in a matching rhythm as well, so the vibration gets stronger the closer her lips get to the base of your penis. She's getting off on this too, and her eyes shine brightly when she looks at your face.

You ask your pet if she's enjoying herself as you reach down to stroke her back encouragingly. Jane nods without stopping her movement.

"Play with yourself," you tell her. At the moment she has one hand on your hip and the other wrapped around your shaft, moving up and down the part that her lips haven't gotten to. She takes that hand off you and grabs her left boob, squeezing it playfully while she pushes herself to take more of your cock in her mouth so her lips and tongue can reach where her hand was.

"Do you want to try any other patterns or zones?"

Jane shakes her head vigorously, well as much as she can with her mouth lodged on your dick. It seems she's really enjoying this setting, and so are you. It might be time to let her out of her chastity belt after this. You let Jane keep sucking your dick at her own pace while she fondles and massages her breasts. Despite how foreign the sensations coursing through her body must be she remains focused on your pleasure, licking your cock and adjusting the intensity of her suction to contrast with the pulses created by the vibrator trapped inside her pussy.

You don't hold back, moaning as you reach your limit and fill Jane's mouth with a stream of cum. She swallows quickly, her cheeks bulging a little before she can get it down. You let Jane keep going for a few seconds, then you pull out and flip her onto her back. Jane yelps in surprise, but before she can ask what you're doing you've latched onto her right nipple, sucking hard as she groans loudly. Her hands hover for a second, not sure where to go, then she wraps her arms around your shoulders and hugs you to her body while you suck away.

Your own hand comes up to tug on her free nipple, and you gently nibble on the one in your mouth to make Jane gasp. "Keep going master, please keep going!"

You pinch one nipple and lap at the other with a flat tongue while opening your mouth to take in more of her tit. Jane coos softly and holds you tighter. You don't let up, swirling your tongue around her areola and pulling on her nipple. The buzzing nubs are a lot of fun to play with, and you get lost in what you're doing for a while. The only things you're aware of are Jane's breasts and the progressively louder sounds she's making, which are like music to your ears.

You come back to your senses, realizing that while your mind was drifting, so were your hands. One now is tugging in ways that mimic the pattern, the hardest pinches with the fastest vibrations, the greatest cupping with the strongest vibrations. The other circling the base of the tit in your mouth. You slurp up the puddle of drool you've let collect on it. After a second, your flat tongue scoops up any residue your slurp missed.

Jane squirms underneath you, so close, almost there. Her body undulating in an attempt to press her cleavage up. You raise your other hand so that both nipples are enclosed by fingers doing mirrored motions. When the vibe is at its strongest and fastest and you are pinching and cupping the most, that's the moment the dam breaks. The undulating stops as she freezes. You hear a gasp before she collapses in relief.

By the time Jane's orgasm is over you're ready to go again.
