Hey there, so for this roleplay I'd like to play it out as if it was a normal Undertale adventure up until the end of the ruins when Frisk (my character) fights Toriel, a new option shows up for Frisk and that being to fuck Toriel. Throughout the rp the more and more main characters Frisk fucks the more powerful they become, and maybe their dick size can increase with every level gained. Also for the characters like Papyrus, Sans, Asgore and other male characters I'd like for them all to be women instead
