Trevor had a much lazier morning than Jon. He was drifting in and out of sleep as he lay nestled in Sharon's bosom. He was feeding off her whenever he started to wake up and it would quickly put him back to sleep again. When he finally couldn't drink any more, he started to wake up calmly. Sharon was fast asleep, content that Trevor was taken care of and quiet now.
Trevor just stared at her, initially with mother's milk on the brain seeing her as his "mommy", the woman who would take care of his every need and always be there for him. As the fog started to lift from his brain his teenage mind came to the front and he stared in awe at the bare naked breasts before him, crowned by two big juicy nipples. He couldn't believe the access he was getting to a pair of boobs. The kind of access he had previously dreamed of. As he stared his penis started to grow erect inside his diaper. He adjusted the short nightie he was wearing to see his diaper bursting at the seams but for once it wasn't because of being wet, it was because of his raging boner pushing it to its limits. He reached down to rub himself through the diaper. He had to be careful as when he rubbed it, his diaper made a crinkling sound. He was enjoying this time to himself and didn't want to wake Sharon. He continued to rub his diaper with one hand and growing cheeky he gently placed his free hand on the soft, silky material of Sharon's panties, feeling how they clung tightly to her juicy butt. He didn't notice but his movements woke Sharon up and looking down at him over her own breasts she said, "Morning sweety." This scared Trevor as he wasn't expecting her to wake up. He quickly let go of his diaper and started to panic. "She's going to think I'm a pervert," he thought to himself. His teenage brain was worried she'd be disgusted by what he was doing and his baby brain was scared he'd upset Mommy and she'd be angry at him.
But Sharon didn't see anything out of the ordinary. It was normal for her to have her babies hands roaming as she fed. There was nothing sexual about it in her mind. When she saw Trevor touching his crotch through the diaper her only thought was that he must be wet. She reached down and squeezed the front of his diaper, the magic of the stone making her oblivious to the erection inside. She was just checking if it was in fact wet. Thus gentle touch from Sharon's hand was all it took to send Trevor over the edge and he exploded with an orgasm, which was easily contained within the diaper.
"Oh, you're soaked again baby. Not to worry, Mommy will get you cleaned up in just a minute." Sharon soother him. Overcome with embarrassment and some remaining fear Trevor just looked at her sheepishly and started to whimper. A few loose tears rolled down his cheek. Seeing his anxiety Sharon simply pulled him in close to her chest again and spoke softly into his ear, assuring him everything was OK and that she was here to take care of him. Trevor finally started to calm down and looked at Sharon again with a smile and said, "Thanks Mommy. Your the best." Sharon didn't understand most of what he said but when she heard her baby say "Momma" for the second time that morning she squealed in glee and squeezed him tight in a big hug.
