Sweet Vanilla loving with Senpai.
Good job on inviting her out on the trip though. Sure, she made the first move, but he helped with the perfect set-up.
Also they really should just get married already.
Although not depicted, it's quite possible that their friends and relatives *cough-cough* "KNOW" why this story's couple is 'out of town' for a while (wink-wink, nudge-nudge). Perhaps some of them might even have "felt a disturbance in the Force" as things progressed.
Still, it was cute enough to get the job done, ... and sometimes, that's good enough.
This is really nice.
