Party at my pad when I was 15, she was 19 or 20.
Had my own place as my dad had a rental property that he was too lazy to get a new tenant for at the time, so it became the local hang for my friends, most of whom were in their final year at highschool or Uni at the time.
But yeah, awesome party with all of them, and this girl, Iz, said "I'm gonna do the virgin..."
It was pretty cool, and I was going at it hammer and tongs until my best friend stumbled in freaking us all out.
me: "Dude! WTF!?"
him: "Shit! Sorry man! You're still going?"
Me: "YES! WTF do you want!?!?"
him: "Oh, we're out of toilet paper... do you have tissues in here?"
me: "YES! They're on the desk, NOW GTFO!!!" ← I should point out at this point, I didn't actually speak in acronyms, I'm just a lazy typist
Anyway, he goes and gets the tissue box off the desk, and I resume my current activities... until I notice this repetitive Fft! Fft! Fft! sound that wasn't in time with the bedsprings.
I stop, look around, and there he is with a few other friends, just pulling tissues from the box, and watching us...
I'm not sure if it was because it was my first time, or just so many people watching, but it's damn hard to keep wood with intent stares like that from the doorway...
