Cumming on Tablet Screen - Need HELP!!

I was extremely excited about this new sensation and experience. It really felt like she would be close to my hard dick, and really felt like I was actually really about to cum on a real person's face!! BUT... as soon as my penis started shooting the whole experience went wrong. As the shooting sperm touched the screen, my tablet "thought" I touched it with my finger. Unfortunately, this made my tablet rewind the video to the beginning, where nothing was happening! So there I was... wanking... OR: TRYING to wank and cum hard, but had no video material to watch as my cum rewinded the video to the start of it!

I was soooo annoyed... I was about to have one of the most amazing masturbation session ever, with a fully reality-felt-like orgasm at the end... buuuut... my sperm rewinded the video from the best part to the most boring part of it (the beginning)!

Any ideas how could I cum on my tablet's screen without making it rewind/stop/change the video I am playing? Tips, ideas, advice much appreciated. Thank you all.
