She looks away, unable to watch as her boyfriend positions himself behind her. She's nervous, her heart pounding in her chest. He's big, and she's not sure she can take it. But she's committed now, and she won't back down. She feels him at her entrance, hesitating. She takes a deep breath and pushes back slightly, giving him the signal. He slides in slowly, stretching her. She bites her lip, trying not to cry out. He starts to move, and she focuses on the sensation, determined to enjoy it.
