Step-Mommy Science

Welcome back Dark stepMommy, part 2 in the series: find part 1 here --> "Dark stepMommy Makes U Eat Cum"

There seems to be some confusion. When stepMommy told you you could masturbate in the house, she didn't mean just.. jerking off. You've been leaving messes all over. In the sheets, your underwear.. and don't think stepMommy didn't notice your crusty tissues.
She is LIVID, seething. She thought you how do do it, how to touch your penis until it squirts, how to aim it into your mouth and SWALLOW IT DOWN.
You talk back to your stepMommy, and she is not impressed. She tells you there is going to be an experiment, an assignment. You will jerk off in this house, 3 times a day, for 3 weeks. You smile.
Oh, you think this will be fun do you? Ok tough guy, stepMommy is going to supervise. Each and every ejaculation, you will cum into this plastic cup. Then stepMommy will weigh it, log the results, and ensure you SWALLOW IT ALL. And she does, over and over again. Watching you jerk off, even when your penis is sensitive from all the touching. You only have yourself to blame. There is only the Right Way. The stepMommy Way. She watches you, scolds you for not utilizing all that precious semen, weighs it, and logs the results. In the kitchen, in the living room, even while she's in the bathroom taking a pee. She knows you like her tits, so she always makes sure to pull her tits out. They always make your cock hard. They always help you cum. And stepMommy LOVES watching her boy cum and consume it.
At the end of the 3 weeks, stepMommy is ALMOST proud of you. But not really. Had you been doing it the RIGHT way, we wouldn't be in this mess. And after chronic masturbation, you now have to STOP masturbating for 3 whole days. That's right sweetheart. No jerking, no stroking, no cumming. And stepMommy will know if you cheat.
Three days pass, and stepMommy is so pleased. She knows your balls must be throbbing, so full of all that previous seminal fluid. She knows you're excited, and she is too. But before you get to cum, there is one thing you have to do first. Get in the shower, scrub your body CLEAN, and shave off ALL your hair. That's right, neck to toes, stepMommy wants you as smooth as a dolphin. She'll be waiting for you when you're done, just put on your robe.
You return to find her in bed, wearing her silk robe. She asks you to take it off, and let her look. She is VERY pleased. Not one single hair is left on your body, smooth everywhere. And she is very happy with the attention you put on your genitals. She loves the look of your smooth hairless body.
Now for the hard part. stepMommy is going to help you. Lay down, and put your legs up. Up up up. That's a good boy. Over your head, YES, just like that. Now point your penis DIRECTLY at your open mouth, and stroke it.
stepMommy loves watching your smooth penis, stroking towards you open little mouth. The RIGHT WAY. We only do it the RIGHT WAY. And you cum so much, the experiment worked! You produced so much cum! But don't swallow it, hold it in your mouth. stepMommy wants to cum looking at that.
She straddles you, touching her pussy, looking at that massive load of semen in your mouth, your smooth body, it makes her so horny. She's so close, and she doesn't want you to swallow a moment before OR after she cums. WHEN SHE CUMS, you will swallow XO
