Sophia dips her toe in.

Sophia looks from Diana, to you, and then to your hard cock. She absentmindedly plays with the top button of her flannel. You look longingly at her lips, wishing they'd wrap around you and pleasure you.

Slowly, hesitant, she leans forward, like Diana did just moments ago. Holding onto your shaft with a thumb and two fingers, she she brings her mouth just millimeters away from the front of your cock-head.

What feels like an eternity passes, as she gets used to being so close. Then, she lets out just the tip of her tongue, quickly flickering it up your tip. A quick micro-instant of pleasure. Then another flicker, slower. Then a little longer, a slow, warm line from the base of your head almost to the tip. Finally, she lets a little more of her tongue out, covering almost the whole width of your cock-head with it as she licks you all the way to your tip. You let out a deep sigh as the pleasure stretches up into your belly.

She looks up at you and gives you a tiny smile. Then she starts another series of faster licks, but this time more consistent. You start to lose sense of time, as each quick burst of pleasure is replaced by another as soon as it's gone. You try to push into her, but there's nothing to push into; her mouth isn't wrapped around you. At best you can lean into her tongue a little bit, increasing the stimulation only slightly. But if you lean in too much, she backs aways, always maintaining the same distance.

It's frustrating, yet nevertheless, you're breathing in shallow breaths and you're lost in the pleasure and the desire. Looking down at her, she seems to be enjoying herself, watching your half-closed eyes, holding your cock with one hand, covering your cock-head with rapid licks. You can still see her perfect, bare legs, still uncovered from before, and although just moments ago her knees were together in nervousness, they are now relaxing open as she covers you with her tongue.

You can feel your pleasure escalating rapidly. If she'd only suck your cock you'd probably come instantly!
