You watch in awe as Isabell expertly takes you into her mouth, her tongue swirling around the sensitive flesh while her hand continues to stroke you in time with her movements. Her moans fill the otherwise silent library, echoing off the walls and driving you wild with desire.

Her other hand reaches up to fondle your balls, giving them a gentle squeeze before moving lower still to circle your perineum, teasingly close to your entrance.

As she continues to deepthroat you, her movements become more frenzied, and she begins to make these strange little moaning noises deep in her throat that send shivers down your spine. Your fingers tangle in her hair, urging her on as you feel the familiar tightness building within you.

Her hand finally finds its way where it's been longing to go all along: between your legs. Her fingers press against your entrance, stretching and teasing you mercilessly as she continues to suck you off.
