The surprise party had been a blast, everyone had a good time, and had left in good spirits. Orchestrating the whole affair had really sapped you, and you welcomed your girlfriends offer to clean up the party, while you pick up take-out for the two of you. There wasn't much of a mess, just a few dishes, and the hilarious number of balloons which had filled the flat up to your ankles - but having to be around to endure the sound of popping them after that draining evening would surely upgrade your mild headache into a loud migraine.
It wasn't a difficult drive, at this hour of the night- it was just the thing you needed to recharge after having exercised your socialite skills to exhaustion. You always found driving relaxing, and combined with the smell of warm food on the way back was enough to liven you back up to normal. In hindsight, you probably should have told her to not pop the balloons until tomorrow, for your neighbors sake- hell, all of cleanup could have been saved until tomorrow. The party must've drained you more than you thought if you were to have such a lapse in common sense.
Luckily, your doorstep wasn't occupied by irate, awoken neighbors. Your modest flat was more or less back to its standard state, give or take a few pieces of confetti- and the sea of balloons that had enveloped the floor was no more. Had she popped them all, this late at night? Or..
In the front room she sat in front of a pile of empty balloons, and a small handful remained to her side. Unaware of your presence, you watched in awe as she took one of the few remaining balloons, bit off the knot and inhaled its contents, before spitting the remains and empty balloon in the pile. As she sucked down each balloon, her gargantuan backside distended further outward, looking more comical by the second.
The fatigue of the party a distant memory, you were immediately possessed with a second wind, knowing there was one last thing you had to do before ending the night.
