Atom-sama had an idea.
Atom-sama backed out because they were disgusted and afraid.
Atom-sama is sorry.

You and Underfell just did the do, you got banged, he made you his bitch, whatever you want to think, guys and gals. I ain't in this no more. But I will probably try again in the future when I'm not ABSOLUTELY TERRIFIED ABOUT THE THOUGHT OF SEX AND I'M NOT AWKWARD ABOUT WRITING IT!

Anywho, bye bye Bombshell Beauties.
