>"Anon!?"
>You freeze, still half inside Derpy and still with your arm wrapped around her leg.
"U-Uh.. Hey, Dashie!"
>"What the fuck is this!?"
>She storms into the room, ripping off the head of her wonderbolt suit and pushing you aggressively so you fall onto your back.
>The grey pegasus quickly hovers up and away from the bed, blushing and trying to hide herself away.
>"Oh, so I'm gone for one hour and you're fucking some other mare in our bed!? What the fuck is your problem, Anon?"
"Look... we just got a little carried away."
>You reach out to comfort her but she's having none of it, swiping your arm away.
>"I'll say! Is this what you're always doing while I'm out? I'm not good enough or something?"
"No! I love you, it's just..."
>"Just what? Strangely enough, Anon, when you love somepony you usually don't go and fuck somepony else behind their back."
>She holds her hoof against her brow and sighs, still shaking with anger.
>"You know what? I'm done."
"Wait.. what?"
>"We're through! You can just go fuck little miss retard over there. Y'know, you were really lucky, Anon. I actually loved you, and some of the things I let you do to me... you're gonna have a hard time finding anypony else who'll do that shit. Now get out of my fucking house."
"Where will I go?"
>"Not my problem."
"I can't even get back to ground level without-"
>"Not. My. Fucking. Problem."
>Her face is practically pressed up against yours, nostrils flaring and eyes fixed with indignation. 
>You can tell she means it.
>Leaving the room, you glance back one more time. This is really it. You can't say it's not your fault, but you also can't say you don't miss her already.
