You push your pelvis up into the air and in one quick motion slip your thumbs under your waistband, pulling your briefs down to your knees. Your cock triumphantly just out into the cool air, red, veins throbbing with intensity that you've never seen before. For some reason... your dick itself is really turning you on.
Inside your mind a new, foreign thought starts to propagate. Quietly, at first, but it quickly rises to the forefront, pushed on by your sex-addled mind.
"Put the bracelet around your cock."
Wh-what?! Why am I thinking th--
"Put it around your cock."
Your eyes glaze over as you robotically slip your thumbnail under the strap wrapped tightly around your dainty wrist. With some effort, you manage to pull it off, and immediately slide it over your massive erection... slowly sliding it down, accidentally touching the shaft as you go down, eliciting jolts from your penis as you do. Finally, you make it down to the base of your penis, and with some effort, stretch the band around the base of your scrotum as well.
As the band snaps around your balls, your mind snaps back to reality. You gasp aloud as the sensations from what you just did hit all at once: "OOOOOOOO-OOOOOOH!". You place your hands flat against the ground, breathing heavily, pushing your dick up into the air with slow, consistent thrusts. At the top of each thrust, you can see the band wrapped around the base of your penis, pinker, and tighter, than before. The tightness of the band making your penis swell tigther, feeding pain and pleasure into your mind all at once.
