Taking my schoolmate home

I never guessed the girl from my evening class would use her mouth like this. Her tongue finds new rhythms each time it drags over me, pulls, circles, flattens, then coils again. Heat builds too fast, sharp and sudden, and my hips buck into the sensation before I can stop them. She keeps her grip tight, rolling my balls in her palm while she swallows me deeper, deeper, until my mind blanks. She pulls off only to breathe hot air against the wet tip, then sinks back down with a hum that runs straight up my spine. Sweat sticks my shirt to my back. My fingers knot in her hair. She works me until my legs shake and words fall out as groans. When I come, she drinks it all, never easing off until I twitch from the sting. As she wipes her lips she already smiles, and I know this will happen again. And again.
