Getting to school early was no problem, but it seemed like finding Kate was the issue as it was Jake who confronted you first.
"We need to talk." he says before pulling you into the restroom nearby. Your heartbeats quickly in anxiousness as you remember what happened the other day, but also strangely of anticipation as he gently grabs your wrist. Thankfully, there was no one else occupying the stalls or the sinks, leading to both of your relief.
"Look. We're best friends, right? It's definitely awkward to think about what happened in the locker room after gym class, but we can't pretend like it didn't happen" Jake says with a bit of a blush on his face.
"I know, you'd think fucking your best friend would be the last thing either of us would ever have cross in our minds, huh?" you say nervously back.
"I mean, you're dating Kate and I'm with Kristi, and there's no denying we love them. There's no doubt in my mind that we're straight. So, just so we don't have to live with this awkward tension every time we see each other or hang out, let's just see what we did as friends helping each other with sexual release. You know, just a friendly fucking, totally no arousal or sexual attraction between us. I mean, that's what friends do, right? Help each other?"
You weren't aware of it, but the bathroom Jake had brought you in was the same one where you cleaned your protein shake-induced cum stained underwear, with the hasty situation causing you leave behind quite a few residue of semen, which now wafted in the air and into your noses as you talked, causing a bit of haze in the both of you. That haze was veering Jake's explanation way off track into illogical sexual reasoning. A reasoning that you couldn't find any faults in as you continued to breathe in the vanilla and banana scented semen.
"Of course, Jake! We're best friends, and I don't want something as small as homosexual fucking to drive that between us." you say, placing a hand your friend's shoulder. "And like you said, there's nothing wrong with two straight friends helping each other relieve tension."
Jake blushes at your touch, looking down before giving you a sly smile on the way back up. "Speaking of which..." he says, trailing off as he gestures down to your crotch. You look down yourself and blush at the sight of your pants tenting from the protein smell. You couldn't help but smile back.
"So... We still have about half an hour until class... You up for some friendly fucking? Just to relieve some tension of course."
Jake's response was simply a kiss to your lips and pull you into the same stall you cleaned your undies in. Pants were dropped as you both continued wrestling each other's tongues and pumped each other's cocks. After a bit of warming up, the two of you separate with a line of your mixed saliva bridging your mouths before Jake turned around, getting on his knees and leaning on the cum stained toilet seat.
You didn't think twice and immediately began thrusting your erection into his ass. An ass, you noted to be slightly more rounder than yesterday as you gripped them firmly but gently. The two of you did your best to hold in the moans as you used your increasingly rabbit-like feet to bounce in and out of his ass, his own slightly shorter feet thumping against the cool tile in excitement.
Soon, the two of you cover your mouths as you both climax: you into Jake's ass while Jake onto the underside of the toilet bowl, the smell of his cum now mixing with your old and new scent. You both relax for a bit from the orgasm, sharing one last kiss with a smile, your sex addled minds still convinced that despite the sex you both just participated in, you were still straight for your girlfriends.
Thankfully, you and Jake made good time and had just enough time to quickly redress your pants and still make it to your class on time.
