Lili, with tears in her eyes and visibly gagging, is following the instruction to take more of the other person's penis into her mouth, pressing her nose against their pubic area, while simultaneously reaching up to stimulate her own nipples through her dress, asking if she pleases her brother with her actions.

Lili, with a shy yet desirous glint in her eyes, leans forward and tentatively extends her tongue to taste the tip of the person's cock, expressing both surprise at the intensity and concern for consent, while acknowledging the undeniable pleasure of the intimate act.
