You pick

By the time Jane has finished orgasm, you are ready to go again. You just want to rip off the belt and have at her pussy. But what about the belt?

"This time I'm going to pick what the vibe does." You grab your phone and start flipping through the app as fast as you can, shutting down the current program and selecting the first thing that catches your eye on each screen. You hear her sigh of relief as the program stops.

"Here. See if you can guess what you're supposed to do next." Pressing the button to start your program, you hear a slight gasp underneath you.

"It's a drumroll in my pussy!" she says. There's the faint buzz matching the pattern she described. "Oh, wait. The second drumroll is in my pussy and my hands." She starts to wave her hands side to side.

A whole other drumroll passes before she moves her hand to your dick. However, she does time it right as she grabs it just in time as the next drumroll begins. She holds onto you for the duration of two drumrolls, but then she flings her hand off you at the end of one. Her fingers are splayed wide as she shouts, "Tada!'

OK now you know what that one does. You start to thumb through the pattern options again. Fingerpicking catches your eye, but it might excite your distracted pet too much. You opt for a safer worm pattern.

Sure enough, soon she starts matching the pattern and tries to reach the ends of your dick at the high and low point of the undulating pattern. With her twisting her hand too, it's an intense feeling. But it's also monotonous after a while. You face your phone again and go back to the main control screen. This time you play with the speed and intensity sliders.

She can't keep up with the changes. You feel her hips shake occasionally, the tremors travelling up her core to move the flesh between your legs. Finally she gives up trying to match the pattern with her hands, and just wraps one hand around and strokes up and off and then wraps the other hand around to repeat the journey. There's always a hand on your dick.

You switch the pattern to something easier for Jane to mimic. You keep the rapid pulse going between her legs for her pleasure, but now each pulse only travels up one of her arms, creating an alternating rhythm in her hands. Jane smiles at you, grateful for the change, and places both hands on your cock. She strokes you eagerly, holding you with a light grip so she can twist her hands around as well as moving them up and down, squeezing tighter each time one of her hands pulses.

This feels like the perfect pace for both of you, so you put the phone down and let her keep going. You knew you were close when this began and sure enough it's not long before you feel your climax building. "I'm going to ..." That's as far as you get before you spray all over her chest which is still glistening slightly with your saliva.
