The answer should be obvious. You need to taste her breasts.

You and Carol double team her, Carol licking her most sensitive spots while you suck and gently bite on her nipples. Grace whimpers as your teeth gently nip at her sensitive flesh, and you hear her giggle as Carol gets her off with her tongue.

You kiss her neck, '''Does that feel nice?'' You ask.

Grace whimpers, ''Mmh, yemsh...''

''Good girl.'' You whisper into her ear. You and Carol give her no pause. You suck her nipples, massager her breasts and kiss her all around her neck. Carol goes down on her eagerly, and this goes on for minutes. Grace whimpers and cries out, her face turning redder and redder by the minute.

'''Do you want to cum, Grace?'' You ask, stroking her hair.

Grace moans, ''Mm... Yemhshs... Mm...''

''I didn't hear you. Louder, speak through that gag!'' You command.

Grace whimpers, ''Y-Yemshs... Yghmesh, I wmhant to cughm...'' She looks up at you pleadingly. ''Plemhase, I cahmn't tgmke imht...''

''Fuck, you're so wet. So hot.'' Carol coos, continuing to lick her pussy. ''Are you going to cum?''

Grace nods frantically, ''Ayyy...''

You smile, a sudden sadistic spark igniting from within you as you pinch her nipples with a little more **** than before. Grace lets out a muffled scream, her eyes rolling back as she feels herself nearing orgasm.

''Oh? You like the pain? My, my...'' You smile, pinching her harder.

Grace lets out a faint whimper, ''Uuuh... Ahhhh...''

You chuckle darkly, ''You can go ahead and cum, Grace.'' You massage her breasts roughly. Carol speeds up her pace, you both know Grace is close. ''Cum for us. Let our tongues lick every inch of your body clean.''

Grace tries to answer through the gag, '''Mmh...'' She gasps.

''Louder, Grace!'' You demand. ''For the entire castle to hear!''

Grace whimpers, ''MMHHH... AHHHH!!'' She cries out as she climaxes.
