Between his mouth and her position, she hung between pleasure and pain, vibrating between the two. The edge of the counter dug into her back, deep enough that she knew there would be a pressure mark. But she couldn’t do anything about it, because what he was doing just felt so /good/. It made her /want/ and stole words from her mind, until all she could do was gasp and pant and moan under his ministrations.
Mentally filing away the erotic picture before him, Isaac let out a faint, needy moan and rocked his hips against her thigh, angling his own body so that his lips could get a better grip on her. Smiling against her skin, his teeth grazed over the hardened nub and he gave them both a curious lick.
When he went from suckling to licking, she twitched again. One leg hitched around his hips. “I need … need … ” She couldn’t find the words for the burning in her body, the way every nerve ending seemed to tingle. She squirmed against him, mindlessly trying to achieve pressure.
