She pushed him over, gently, and continued to kiss every part of him she could reach. It took a moment of rearranging before she was comfortable, draped against him, and then hesitantly she put her hand back on his erection. Her eyebrows flicked up, slightly, as she found the damp spot pre-cum had made on his pants.
Trembling with a combination of anticipation and nerves, Isaac licked at his lips and glanced down once more, eyes widening as she moved even closer to him. Rocking his hips forward the instant her hand met his erection, he let out a low groan and angled his neck back, his eyes fluttering shut.
She could /smell/ him — it was strange. Not a bad smell, at all, but she wasn’t used to being so close to someone that she could smell them. She stroked, slowly, thinking about the way he fit into the palm of her hand, about the size of him and the length of him. She kept checking his face, hoping the sounds he was making were good and not pain. Finally she got frustrated with the interference of the fabric and pulled his pants down.
