Kim packs her bags (pointedly skipping her underwear and sock drawer, thinking you will cover that territory) and hops onto a bus to her expenses paid gaming tournament. She somewhats snubs Jen and Faye on her way out, not wanting to bother with the opportunity of them finding out your whereabouts. It would only be another week, tops, if all went well. Then you would be free, probably. She tries not to think of the future details, or the heavy, sloppy, breakfast burrito fart she flaps into your face, as she boards the bus. She specifically waited until everyone else boarded to let it loose, momentarily allowing herself to forget she was not the true caboose of the passengers.
You were stewing in the semi-liquous miasma of Kim's personal airs, your eyes rolling into the back of your head as you unwillingly filtered her gases through your nose and exhaled fresh air for the passengers to smell; the feeling of your fresh exhalations cooling off the slight burn in Kim's asshole to her hard to control delight. As far as they were concerned, Kim merely played a fart noise, or had a scentless emission, and a few girls chuckled alongside what they thought was a merry prank. If they knew the true contents of what they heard, or the effect it was having on your mentality, they would likely view Kim as somewhat of a psycho. However, your roommated and captor would be the only passenger on this journey who would even know your condition was possible, let along have you massaging her rectum.
Trying again to put your suffering out of her mind, instead gaslighting herself into the narrative that the two of you are working together to secure rent money, Kim pulls out her portable game and begins to play.
How does this journey fair for the two of you?
1. The bus ride goes well but the tournemant goes horribly. Kim is completely out of her depth; outside of the sphere of players she is used to she is completely delusional about her abilities and comes in amongst the dead last. In such despair, Kim either takes her misfortune out on you for potentially losing your luck or distracting her. Or in such misery of her defeat, Kim completely forgets you tagged along and she spends her entire trip wallowing "alone" in a hotel room, with only you as her sole underwear.
2. The tournament goes amazing, and Kim is amongst the top players. She begins to feel a romantic attraction to you for supporting her so graciously during this time; and despite whatever protests you can muster, you may be trapped in this position for even longer with even scarier contexts.
3. The bus breaks down along the way! Camping out at a rest stop, does Kim somehow slip you are accompanying her?
