Oral sex

You wake up to a half dozen gasps as the next class starts to filter into the room. The girls are staring at your naked body. You don't explain, just let them wonder.

You are tired of the decor in the room, so the abstinence posters are replaced with "Sex is fun and healthy" posters -- this is health class after all. No more safe sex posters, since STDs are a thing of the past. The clinical images of the reproductive organs are replaced with full-color nude photographs of men and women, by themselves, in pairs, and in groups. One whole wall depicts various sexual positions, arranged by difficulty. The last few sections are labeled "Extra Credit".

Once the bell rings, Ms. Patrick, whom you have tweaked into a sexier version of herself by firming everything up and giving her better clothes, introduces you to the class like last period and turns things over to you.

"Girls, today's class is on oral sex. Let's start with terminology. 'Fellatio' is the art of the blow job, and 'cunnilingus' is the art of eating pussy." Several girls giggle at that terms. "Each of you will have an opportunity to show me what you know about fellatio, as well as practice cunnilingus with each other. Now, everyone must remove your clothing." Many of the girls make grumbling noises about having oral sex with other girls, until you get rid of the same-sex hangup.

You survey the class, seeing Betsy Ross, a pretty brunette girl with a beautiful wide mouth with big lips -- perfect for blow jobs. Her parents should be jailed for naming her Betsy, but nobody's perfect. Once everyone is undressed, you say, "Okay, find a partner and practice eating each other out. The girl who is receiving should give pointers about what feels good to their partner. Betsy Ross, you're first with me." Betsy smirks a little as she walks up to the front. You sit in a comfortable chair that wasn't there a second ago. Betsy kneels on the thick, padded fur rug at your feet.

"Show me what you know," you say as you lean back in the chair. Betsy scoots close between your knees, staring at your rigid member. She reaches for it and runs her fingers up and down its length. You close your eyes and enjoy the moment. When her lips surround the head and both of her hands grasp the shaft, you suck in your breath and let it out slowly. Her tongue flicks wickedly around the base of the head, then she pulls off and licks your cock from balls to tip. She wiggles the tip of her tongue in your cyclopean eye, before she swallows about half of it. This girl has done this before, more than once. You picked well.

With one hand, she fondles your balls as the other holds the base of your cock. She begins to bob up and down, taking a little more on each descent. When she gets about two thirds of it down, she gags and then pulls off completely to hand-shuck you. While she's pausing, you remove her gag reflex and subtly modify her throat to comfortably take nine inches. Then you change her memories so she knows she can take it all. With the room filled with moaning teenaged girls going down on each other, Betsy dives back on your cock and quickly gets all of you down her throat. With her lips in your pubes, she starts swallowing like a hooker, squeezing the head of your prick in the back of her throat. Such ecstasy you've never had from a blow job.

You growl and thrust your hips up as you explode inside her mouth. Your cum goes straight down into her stomach, until Betsy pulls back, swirling her tongue devilishly, and collects the rest of your cum in her mouth. You make yourself keep coming so that some spills out of her mouth onto her chest. You change reality to make your jism taste sweet and fruity, as well as give it skin toning, acne-curing, and anti-depressant properties. Betsy gulps her mouthful down and grins at you. Her complexion is noticeably better. You watch as your cum drips from her perky, apple-sized tits.

"Oh, you get an 'A+' for today, Betsy. That was the best blow job I've ever had." You look around the room, noting the moans and heavy breathing, and add, "Go switch with Annette and send her over. You can practice on Sally, Annette's lab partner." Betsy bounces away with a sparkle in her eyes.

Annette is a cute redhead, who unfortunately has bad acne. She is not an expert cocksucker, but with a little instruction and the silent use of absolute power, she's nearly as good as Betsy by the time you explode. Instead of holding all your cum in her mouth, she keeps swallowing as you spurt. By the time you finish, she's consumed about a cup and has the clearest skin in the room. She smiles and laughs as she wipes at the cum on her nearly-white grapefruit-sized boobs, sucking her fingers hungrily.

Next is Gretchen, a German foreign exchange student. With a little pushing from you, she lets her hair down literally and figuratively while she's blowing you. When you come, she pulls off you completely and jerks you. She giggles when quite a bit lands in her hair. She offers her cum-covered tits to you, and you oblige her and lick them clean. The moans she makes when you suck her nipples get you hard again. When she goes back to send Emily to you, you notice that her new partner starts by licking the rest of your cum off her body.

You have to manipulate time in order to get through all twenty girls, effectively fitting two hours of oral sex into one hour. By the end of the period, all your classmates can give a good blow job and decent cunnilingus, and have blemish-free skin and upbeat attitudes. You decide to extend the special properties of your sperm to all men. That should encourage more blow jobs, once women figure it out.

You are tired and drained -- literally drained of body fluids. You still have another class before lunch, so you stop time for everyone else, while you conjure a steak and a beer to sustain you, and then take a nap. Two hours later, you wake refreshed, and no time has passed. There is something more satisfying about eating and sleeping, instead of simply banishing hunger and fatigue.
