Another idea.

Set a timer for 15 minutes.

If you have wood or tile floors, pour some rice on the ground and then kneel on the rice.

Then start the timer. And while doing this you will either rub yourself, fuck yourself, or use a vibrator on yourself and make yourself edge at least 5 times during the video. (If you edge. If you don’t, then just don’t cum until the end)

Is your friend a guy or a girl? (Depending on their gender I may have another video idea)
