Snip the end of the condom

Getting a devilish idea for payback, you decide to let Allison play with a little more fire than she bargained for. You know that you're right in the middle of your cycle, and being neighbors, she might be, too.

Through the wall you hear a male voice say, "what the fuck?" You know that if you take too long, things might not get back up to speed next door. You quickly grab the scissors from your desk and make a small cut at the tip of the protective film encasing the dick in your hand, and immediately drop it. Once again, as the dick touches the floor it vanishes.

Then you wait. About 45 seconds later, you hear the sex resume where it left off, and hope that your incision went unnoticed.

You continue to wait. You hear the fucking continue for roughly 5 more minutes before the telltale grunts from Luke.

Once again quiet. A few minutes pass, and you're about to figure they noticed before continuing, when you hear Allison shriek. "Oh fuck! Did it break?" you hear her say, "Shit, shit, shit! Let me get up, I have to wash this out!"

You hear her scamper to pull her clothes on and go out to the hallway. You see Allison's door open quickly and she stepped out, looking ready to sprint in the direction of the floor's shared toilets.
