In the twisted world of Undertale, Frisk's innocence is shattered as Chara's corrupting influence takes hold. Frisk, once pure, now craves the forbidden. Chara, their fallen friend, guides Frisk's hand to their own throat, teaching them the art of deepthroating. Frisk's eyes water as Chara's massive cock slams into their mouth, hitting the back of their throat repeatedly. The room echoes with wet, gagging sounds as Frisk struggles to take it all in, their face a mask of ecstasy and pain.
