Stefan smiled against her skin as he heard her little sound, trying not to laugh and spoil the moment. To keep his mouth occupied, he sucked softly at the little bundle of nerves, before resuming his lapping, letting the tip of his tongue swirl around in a circle as he lifted his hand to stroke her again. His other hand tracing little circles on her inner thigh, Stefan slowly slipped one finger inside her as he built up a steady pattern of hot, wet sucks and teasing, probing licks on her clit. He tried to vary what he did from time to time, aiming to please her as much as possible. They would live for eternity; there was no way he could let sex get boring. He began moving his finger inside her; pulling it back before pushing into her again, twisting it, gently caressing the hot, slick walls of her pussy. After a moment, he pulled his mouth back a little and replaced it with his thumb, taking the opportunity to look up at her, a smug smile on his face.
