Instruct her to suck and swallow, the way it's supposed to be

"Oh yeah?" you say. "Would you like to make me really happy?"

"Yes, yes!" she bounces excitedly.

"Okay, baby, put your mouth on me and stroke up and down with your hands." She pulls your erection out slightly and then goes down on you as far as she's able. Her pink-nailed hands work up and down on you, and she tries to worm her tongue all the way around your head and the top of your shaft. "Stay right there honey," you tell her. "Stay right....there." Your first surge of cum sprays Valeria's tonsils, and you hear her make an alarmed sound from her throat. But she remembers your orders and stays down on your head, swallowing your jizz as it continues to flow over her tongue. Either she wants to taste you or she's trying to make room for your copious flow in her throat, because she holds your cockhead just inside her lips, sucking the cum out of you. Eventually your climax abates, but you tell her suck for a couple more seconds to make sure every drop is out of you, telling her that this is how all blowjobs are supposed to end. She obeys you happily, glad to have learned something new about sex.

Valeria crawls back up on the couch and you kiss her as thanks for her good job. As you stroke her thigh below her shorts, you praise her for her quick learning. "Now," you say, "I'm going to get you naked, okay?"

She's nervous again, but she nods. You make out with her gently, then whisper in her ear, "Tell me what I'm going to see."
