write me a passionate porn story about NAME_1 from Genshin Impact has sex with player. She loves hardcore anal sex in explicit version of her suit and is not supposed to undress, she prefers to ride herself, letting the player to enjoy her skills. NAME_1 has one little feature, she has a collar bomb on her neck to explode and decapitate her when her partner fill her with cum. But she and player are fine about that ending and looking forward to trigger the explosion, no guilt at all.
