Your climax triggered an update to your chastity belt program.

You go on ignoring the dick in the room, though Velvet takes over pleasuring it while you recover. You pull out your phone and read the notification but you don't get many details. It only reads "Program updates applied. Click to view." Of course you're curious to read the details but you're just as apprehensive because the notification came from the same app that's linked to your chastity belt.

Your friend doesn't seem to notice you looking at your phone what with her fascination with the cock she's pleasuring, so you go ahead and tap the notification. The chastity belt app opens up, followed by a pop-up screen detailing what happened.

"New program activated: Cocklust v3 Level 2."

"Congratulations <usrname> on being the 1st subject in the Cocklust v3 program to achieve an orgasm! In accordance with this accomplishment, your chastity belt's programming has been upgraded to Level 2. Please see the changes from level 1 below."

You're not surprised that you were the first girl to get an orgasm like this. This is only your second day wearing the belt after all. Of course, you don't know how many girls are testing the same programming as you.

You skim down through the details of the program and try to see what's different. Despite what the message said, the app doesn't highlight what the exact changes are. From what you see, it looks like your daily teasing time has been increased by 5 minutes, with it using both level 4 and level 5 vibrations. That's not all though, as you see that the belt will use its shock function when you edge, probably to bring you down faster. The one saving grace seems to be the option of removing 5 minutes from the teasing time by having a butt plug inserted during it.

That's not all you find, however. You spot a new section that breaks down your activities:

"Oral: 6, 100%"

"Anal: 0, 0%"

"Orgasm chance only increases when ratios are below 60%!"

That last line gets to you. So far, you've only ate your roommate out once and gave a few blowjobs. That seems to be biting you in the ass now. You don't have it in you to do the math right now, but you know you're going to have to get your ass drilled a few times before you give any more blowjobs.

Blowjobs... right. You finally look up from your phone at Velvet. Your friend seems completely lost in the moment, with one hand wrapped around the cock protruding from the hole and the other snaked up under her shirt and presumably on one of her flat tits. Her mouth keeps bobbing down and up around the dick, which you can tell is a sizeable one when Velvet's head is fully back.

You don't try to join in at all this time. Velvet looks completely content servicing this dick; her eyes are closed and you can hear the muffled moans, probably due to her tweaking of a sensitive nipple. Of course, you don't want to think about the real reason for your apprehension, being that with your new program, finishing off this guy would actually put you further away from your next orgasm.

Velvet's performance goes on for a few more minutes until you spot your friend's eyes shooting open in surprise. You can clearly tell that cock just erupted in her mouth. She does her best, but after you hear the sound of gagging, she quickly pulls back which lets the last shot of cum land on Velvet's face. The cock quickly retreats back to the other side of the wall and you hear Velvet gulp as she swallows the cum left in her mouth.

"Sorry..." She says between pants, clearly out of breath. "I didn't let you finish that one."

"It's fine." You respond, shaking your head. "You ready to get out of here?"

"Yeah... If you're done I guess I am too."

Together, you slowly poke your head out of the changing room door and make sure the coast is clear. You stop off at the sink and quickly try to get the leftover cum off of your chin and neck. Thankfully Velvet seems to have licked up most of it. She still has a glob on her face to wipe off though.

Once you're both cleaned up, you slip out of the locker room and make your getaway. After you get back outside and fall in with some other students that are walking around, you stop worrying about getting caught.
