"Open your mouth," he commanded. "No gag this time, so keep your teeth back." She opened her mouth, keeping her teeth wider than her lips as he slid into her mouth. He moaned as she sealed her lips around him and applied suction as he pressed into her. She groaned around his flesh as he pressed all the way back and into her throat, holding there as she breathed through her nose for a moment. He took one hand and pinched her nose closed, causing her to choke lightly as she gagged on his cock. He pulled out just far enough for her to gasp in a ragged breath before he thrust into her again. "Suck," he commanded, and she sealed her lips around him again, applying suction as her face reddened at the lack of air. Her chest started to pulse with failed attempts to pull in air but she obeyed and then he slapped her cheek hard, causing her to break the seal and gasp in air as he pulled out and then shoved himself back in again.
