You both cum (gain xp twice).

Once Elizabeth knows what she's doing - she's no expert, but youthful enthusiasm counts for a lot - you focus your attention on making her cum. While you squeeze her tight ass with your hands you suck and lick and slide your tongue over her clit, and you're soon rewarded with a muffled cry of pleasure as her body shivers on top of yours, her hips bucking against your face while she moans out her orgasm with her face between your legs.

Once she's come down she goes back to licking you with renewed intensity, and you lie back and enjoy her eager tongue circling your clit, pressing against it, and then she imitates you and sucks it, very softly at first but as you encourage her she does it harder, then flicks it with her stiff tongue, and soon she pushes you over the edge and you cum into her mouth, gasping as the young girl licks your pussy through your orgasm.

When your moans die down she turns around on top of you, snuggling in close, and when you pull her in to kiss her she doesn't hesitate, and you share the taste of each other on your lips.

"Wow," she says with a faint smile, her eyes shining with excitment. "Just... wow."
