Right in her mouth

You warn Rachel that you're about to cum, and she just smiles and clamps her lips down harder around your head, pumping your shaft with one hand, while she kneads your balls with the other. You realize Rachel wants your cum in her mouth, and that drives you over the edge. You sink your fingers into Rachel's soft red hair, and thrust deep into her pretty face. You burst in her mouth with a grunt, hot cum shooting up your rock hard cock and into her eager mouth. The first blast goes right down Rachel's throat, and she looks up at you with those pretty eyes while you keep pumping cum into her. Rachel's hot little tongue laps up your thick cum, as you shoot wave after wave of it into her mouth. Rachel squeezes your shaft and balls, milking your cock and swallowing every drop. Finally you slip free of her silky lips. She gasps for breath, smiling, and you shoot a few more spurts across her lips and onto her tongue.

"MMmmmm," Rachel smiles, "You taste so good." She licks her lips, and sucks your slippery, still-hard cock, tasting and swallowing all your cum, cleaning yor head thoroughly with her tongue. "How was my oral presentation?"

"You get an A." You tell her, helping her up and kissing her. Rachel giggles.
