The second week the sex labs began, and everyone was eager to get started. It was more intense than I had anticipated, both because the girls needed very intense coaching in each session, and the aides got into the training with a passion, which spawned numerous conversations with them on how they could improve the instruction as well. My first priority was with Anna and Suki, who were naturally small and would need a lot of practice with Jared before they would be ready for anyone bigger. They had many weaknesses, from blow jobs to size theory, but that would all have to wait, because during the Diagnostic Test they couldn’t even take all of Jared’s dick without a serious struggle, and I could tell he was going extremely easy on them both, holding a few inches back during his thrusting so that he came without forcing them to take all of his size. And that was only fucking them missionary style. Their biggest priority was to stretch and loosen to take all of Jared first, and then clean up the sloppier parts of their technique. Progress was slow, and it was made slower by Jared’s reluctance to be aggressive when he was fucking them during the labs, and the fact that he never chose them for the freestyle labs, choosing instead to give them a break from his big dick. But by the fourth day, I could tell that he had hindered their progress significantly and that I would have to talk to him about it.

It was during Suki’s session. She had given him a semi-satisfactory blowjob to get him hard, and he was in the process of penetrating her with his big cock. I had him take her doggie style in order to stretch her out better, and he was harder and larger than usual today. I could tell that he was conscious of that fact, being careful not to force it in quickly or thrust too hard. Suki was moaning and straining like she usually did, her ample breasts flopping down on the bed as she braced herself on all fours, concentrating on receiving Jared’s huge schlong. He only had about six inches inside of her tight pussy, and every time he pushed a new inch inside, she let out a yelp. I could tell that she was using her vocal feedback to make him go easy on her, and that she could take much more than she was letting on. It was her fourth lab, and taking Jared’s cock should be easy for her by now. “Push her down on the bed and get on top of her,” I told him, trying to move him into a position where his weight would naturally encourage him to go deeper faster. He did so, moving on top of her little body and straddling her ass with his long legs, his big dick moving ever further inside of her. Suki cried out, though it was muffled by her face being in the pillow, and she moved her legs to thrust her ass out to give herself more padding between his body and hers. “All the way now,” I told him, and got behind him to watch him start thrusting his whole size into her filled out pussy. Jared started doing so, and she groaned in time with his slow, easy pokes. I reached down and put my hands on his ass to feel his motion. He’s holding back, I realized. He doesn’t want to give her all he’s got.

After the session, I ordered Suki out of the room, and handed Jared his clothes for him to get dressed. “You are way too nice,” I told him. “You can’t hold back like that.” He paused with his shirt half on, knowing that I had caught him. “Um, yeah you’re right,” he said. “Look, Jared,” I said. “You think you are being a gentleman, but you are really helping her cheat. Your job is to prepare her for guys who are bigger than you are. She has one more lab with you tomorrow, and then she has to get fucked by Brandon. What is she going to do then? He’s going to tear her up, and it’s all because you didn’t break her in properly.”

“Oh, yeah, I guess I didn’t think about that.”

“Not only that, but you are teaching her bad habits. Every time she hollers, she can get you to go easy on her. You think Joe is going to hold back when he’s fucking her? You think Jason ever would? She’s trying to control the fuck, and you can’t let her do that. She has to be better than that. She has to learn to handle anything you can give her.”

“Yeah, I know, I guess I just have to remember that.”

I sat down on the bed. “Just remember why you are doing this. It isn’t for you, it’s for every hung guy she’ll ever meet in life. Once you break her in, she’ll be able to handle any guy out there who is your size. If you don’t, she won’t be ready to take them. You are doing this to prepare her. You’ve got a big cock, and you have to start to fuck like it matters. Don’t be afraid to do it- they are here to worship your size, and you have to help them learn how to do it right.”

Jared gave a thoughtful smirk. “Yeah, I guess you’re right. That’s true. Thanks, I’ll do better next time.”
True to his word, the next lab was a completely different Jared. Instead of putting up with a half-ass blowjob, he kept Suki sucking his long cock for a full fifteen minutes, only consenting to get fully hard when she had shown that she knew she was no longer in charge, and that the fucking moved on only when he decided that it did. When he finally moved her down onto the bed, she tried to get into her normal braced position, but he turned her onto her back, grabbed her legs and pulled her down close to his body, leaving her feet high in the air and her exposed pussy just below his huge throbbing cock. Before she knew what was happening, he was already halfway inside her bulging cunt, his legs spread out in a wrestling brace and his arms on either side of her head. She cried out in alarm, but he bent down and locked her in an embrace as his hips plunged his fat dick deeper inside her. I could see the look in her eye as she realized that she could no longer get him to do anything but what he wanted, and that Jared’s big dick was going inside her as fast and as hard as he chose to drive it. “Good!” I called out to her. “Just take his size, just like that…focus on what he’s doing…don’t try and fight it, he’s doing great.” Suki passed through about ten more seconds of panic before she started to listen to me, and then began remembering her lessons. She arched her back and spread her hips, breathing deeply to relax her small frame. Most importantly, she stopped struggling and screaming and began moaning in exhilaration. Jared felt the change, too, and delightedly thrust his entire body down onto the girl, sinking his entire cock into her. “Damn, it’s tight!” he said, casting a side glance and smile at me. I winked back at him. He’s finally getting it, I thought.
