The next morning, Robert is up early. He is determined to get to the magic gym and then have some more 'personal time' with Victoria before school starts.
He is almost too early for his parents to question him, as they planned, about some of the changes Robert's body has started going through. As well as ask about all the the noise he and Victoria were making in his room as they studied after dinner.
But whereas previously Robert would tiptoe delicately around the house, now his larger body and feet can't help make thudding sounds as he prepares to leave and saunters down the stairs, which awakens both Bella and John.
His mom calls to him from the top of the stairs just as he is about to leave the house.
"Robert, it's so early and you and Victoria were studying nearly all evening. We're proud of you honey for working so hard as always, but shouldn't you take a little study break this morning?"
"I'm not going to school mom" Robert responds - in a tone Bella swears to herself is slightly deeper compared to even last night.
"You're not?" replies Bella, looking puzzled.
"No, I'm...going to the library." he lies. "There's a book I need to get out for that assignment I was working on with Victoria last night. We won't be able to get top marks without it."
Bella breathes a sigh of relief after her son leaves. Perhaps he's not changing that much after all.

Fifteen minutes later, Cassie is once again putting her newest protégé through his paces. She'd been surprised to find him waiting for her at the gym when she arrived for work but readily agreed to run another session for him so that he could continue his progress. And as the gym is so quiet she's managed to get him to discard his t-shirt so they could easily witness the rapid changes to his arms, shoulders and chest as he continued to work out under her tutorage.
Robert loves the attention he gets from Cassie as he exercises and shows off his newfound strength front of her. Even the slightest touch is enough to give him an instant boner and she giggles at the sizeable bulge he sports as a result.
As they near the end of the sessions and more people start to enter the gym. she whispers seductively in his sweaty ear that they should continue what they started yesterday. Robert glances down at his personal trainer's hot body, his cock visibly pulsing in his shorts and his eyes narrowed with lust.
But something of the old Robert snaps him out of it suddenly. Sure, Cassie is hot but what about Victoria? What they have is special as in addition to being able to explore their developing bodies together, she's his equal in intellect too. Cassie may be 'fucking tight' as he thought he's heard some of the other guys describe it but at the end of the day, she's a bimbo who would never be able to engage Robert in deep conversation or spend time with him solving math problems together.
"Cassie, I...er, have to go." Robert blurts out nervously, backing away.
Cassie smiles.
"Relax baby. Maybe I tried to take things a bit too fast, that's all. Listen, great workout today. You are looking soooo buff now. You should be proud of yourself!"
Robert continues to make his excuses to go but can't help giving his crush a little pose of his bulging bicep before he heads to the changing room.
And in response, Cassie hangs Robert a silver chain that she presents to him as her little gift for doing so well so quickly.
Robert thanks her for it and can't help putting it round his neck as he admires himself in the mirror after he has showered fifteen minutes later. Hidden under his clothes, there's no way Victoria or his parents would even know it is there.
But as he heads out of the gym, giving Cassie a shy little wave as he does, it has already started glowing and working its magic.
