Let her decide

You say nothing, instead taking the opportunity to reach up and fondle one of Lily's breasts. They're so small and perky that they barely hang even when she's leaning forward like this, but you love them anyway. She giggles as you brush a thumb over one dark nipple, still stiff and sensitive from your lovemaking, and almost spills your cum.

Lily hastily closes her mouth, and with exaggerated smacking noises, swallows all your cum in a single gulp. Then she opens her mouth again to show you proof of her slutty deed.

"All gone!" she announces proudly. "Mm, you taste so good," she adds, eyelids fluttering with pleasure as she licks her lips clean.

Lily gently lowers herself down onto the bed, curled up into your side, with her head on your chest.
