Sans, the stoic skeleton warrior, finds himself in a secret, shameful ritual. His large, bony hand wraps around his hard, veiny cock, stroking it furiously as he envisions Chara, his forbidden love, writhing beneath him. His other hand pinches and twists his sensitive nipples, sending jolts of pleasure through his undead body. As he nears his climax, he imagines filling Chara's tight, eager pussy with his hot, sticky cum, marking her as his. With a final, shuddering groan, he erupts, painting the plush Chara toy with his seed, his body convulsing with the force of his taboo release.
