"About the same age as me?" asked Mandy as she toyed with Mike's hair. Mike's head was at the perfect height for her to reach and the 10 year old was so engrossed with Mandy's sexy 20 year old body that he didn't really care about anything else at the moment.
"No problem," said Bobby as he started to form the wish in his mind.
"Just a second," said Mandy. She started taking the clothes off from the non-resisting Mike. The boy's mind was apparently too overwhelmed to really think about what's happening to him or what's about to happen. In a few moments, Mike was just standing there in his briefs. Then Mandy turned to Bobby and said, "Ok, now."
Bobby made the wish for Mike to become 10 years older, physically and mentally. Mike gave a sudden gasp as he started getting taller. His body kept stretching upwards, getting thinner as he became taller. When he reached 13 years, he started to broaden. His shoulders and chest were starting to get wider as his arms and legs thickened so they looked less lanky. All the time, his eyes were locked on Mandy, particularly on the impressive bust that was under her shirt. He could make out a pair of small bumps in the middle of each that were surely her nipples, which means that Mandy wasn't wearing a bra.
Mandy watched as Mike got bigger, his briefs getting stretched tight as he started through his teenage years. She particularly noticed how the bulge in the front was getting increasingly bigger. "Hmm...what do we have here?" asked Mandy before sliding her right hand down the front of his underwear. Mike let out a moan, his voice sounding deeper than before, as Mandy's hand found his equipment and started massaging it. The space within the briefs was becoming more limited as he kept growing.
Mandy noticed how tight the briefs were getting and she knelt down in front of Mike, her head just a little bit above his waist. "These need to go now," she said as she grabbed the waistband with her left hand and started pulling down with both hands. Mike let a sigh of relief as the tight underwear was pulled off, his throbbing boner springing out into the open air. Mandy pulled Mike's underwear all the way down, noticing his leg muscles were getting thicker and hair was starting to appear on them. Mandy had a little trouble when she got to his feet, which had gotten so large now. He helpfully lifted one leg then the other, allowing her to remove the briefs. She then looked back up, Mike was getting taller still. By now, all his muscles were starting to build up as hair was starting to darken across his body. His face looked about 16 years old by now and he was looking rather handsome with his chiseled jaws and broad cheekbones.
Mandy then focused on what was closest to her. Mike's member had grown quite a bit and was looking thick. The balls hanging beneath them were covered in a light amount of hair and were swelling larger. Mandy wrapped her right hand around the shaft while her left land cupped the balls. Mike gave a lower moan at that as his member grew a little longer. Mandy's fingers encircled the shaft with barely any space to spare, but there were at least three inches that were uncovered and the balls filled her palm almost completely. She started rubbing her hand up and down the member while her other hand gently massaged the ballsack. Mike's moaning was lower and louder. Hair had started becoming thicker on his limbs. Hair started sprouting across his expanding pectorals as his abdomens became more defined.
Mandy stroke the member as the head started getting closer to her. A sexual curiosity came over her and she leaned her head further in. Reaching out with her tongue, she gently licked the underside of the head. Mike did a small jerk at that and looked down at Mandy in surprise. Mandy just smiled back up at him before she gently wrapped her lips around the head. Mike moaned louder, one of his large hands reaching down and grasping the back of Mandy's hair, allowing the orange-blonde hair to pass through his fingers. Mandy softly sucked on the tip of the member, her tongue finding the taste of his pre salty but enticing. She released her hands' grip on Mike, she didn't want to get him too stimulated just yet.
Eventually, Mike's growing came to a stop and Mandy took his second head out of her mouth. She stood up and looked him over. He had developed into quite a hunk at 20, broad muscles covering his body with some hair on his limbs and pecs. He was about six inches taller than her now and his face was definitely that of a man instead of a boy's. She swallowed a bit before she placed her hands on his shoulders. It didn't take Mike long to work out what she wanted and he leaned his head down slightly to kiss her. The two of them mashed lips for a while before Mike's hands reached down to grab at her shirt. Mandy broke off the kiss and raised her arms, allowing Mike to remove the shirt with no impediment. Her large breasts bounced slightly as they were uncovered, each of them more than a handful even for Mike's larger hands. Mike grinned before grabbing the waist of her running shorts and pulling them down. His fingers had also hooked her borrowed panties so when he reached her feet, she was just as naked as he was now. Mandy's pussy was bordered with light, soft hair, matching the same golden-orange color of her hair and her lips gleamed with wet anticipation.
Mike sat back down on the couch, spreading his legs out and allowing Mandy a full view of his equipment. His balls had gotten a little bigger and hairier and his boner looked long enough for her to wrap one and a half hands around. Mandy grinned widely as she climbed onto the couch, positioning herself on top of Mike. She grasped his boner with her right hand, which got a little moan from him. Mandy rubbed it a little before she guided it to her pussy. Once the head was pushing against the lips, she started lowering herself. Both of them moaned as Mike entered her and started going deeper. In a second, their pubic hairs were mingling and their mutual virginity was officially lost. Mandy waited until the ache inside her started to dull before she started moving. Her hips went slowly up and down, coxing the cock inside her. Mike moaned before he started helping along. He softly thrust in and out, teasing her vaginal walls. Mandy was gasping in time with her movements, which sped up as she began to bounce with more vigor. Mike was soon matching her with his faster thrusts. Mandy's huge breasts started to jiggle quite a bit as she bounced. Mike reached up and grasped both breasts in each hand, his hands overflowing with bouncy flesh. He teased her nipples a little before he leaned in and latched his lips on one. Mandy moaned as he suckled at first one tit than the other. Her big breasts were so sensitive and pushing her closer to the edge. The pair's movements became more frantic, Mandy riding Mike for all he was worth. Then the peak was reached and both of them let out a loud moan. Mike's cum rocketed up into Mandy's body that was trying to suck all that it could. The two of them panted as they came off their orgasmic high.
Bobby and Ashley watched as Mandy and Mike began making out on the couch. Mike was still lodged within Mandy and it looked like the two would soon be going at it again. Ashley tugged at Bobby and asked, "Isn't it time for us to have fun now?"
In all the excitement, Bobby had forgotten that Ashley was still 10 years old right now. That was a pretty simple thing to fix.
