In our dimly lit bedroom, my girlfriend and I kick off our shoes and climb onto the bed. She turns to me, her eyes sparkling with desire, and whispers, "I want you to fuck my mouth until you cum." I comply, my cock already rock hard. She takes me in, her lips stretching around my thickness. She gags slightly, but I hold her head in place, not letting up. She looks up at me, her eyes filled with tears, but she keeps going, determined to please me. I feel my orgasm approaching, and I warn her. She doesn't pull back. I groan loudly as I cum, my hot load filling her mouth. She swallows every bit, then licks her lips, smiling up at me.
