Britney and Ashley looked at one another as they entered the house. Easy as can be. Britney looked at Ashley for a moment, who just nodded at her - this was followed by Britney hurrying off to the generous upstairs bathroom. Really a lovely combined bathroom / shower room, with both a toilet inside of a small room, and a combined shower / bath area. This gave Britney ideas for what they intended to do with young Jacob.
Meanwhile, Ashley cozied up to Jacob and got him to show her around, acting at awe of his house. It was a pretty nice place, but not the nicest - more just a very good place with two stories that would prove ideal for their plans to indulge with the young sportsman living here, and alone at that for most of the day. Jacob showed the way to a room that had a large number of gym items laying around, and he introduced the room, "This is my home gym. I usually workout at the gym, as you..." he flexed an arm, grinning as Ashley cooed and touched his arm, "...can probably tell."
"You are, like, so incredibly buff, Jacob! Look at you!" Ashley let her hand move from his arm to his chest, and teased his nipple, which made the young hunk chuckle and flex his chest a bit to show off. She looked off to the stairs leading upstairs as Britney returned...still carrying the soap.
"Can you uh, give a demonstration? Like, of a few of these workouts...?" Ashley asked.
"Well...I should be mowing the lawn..." Jacob started, but when Ashley licked her lips and again flirted nonverbally with him, his hormones won out. "...But obviously, you wanna get me sweaty and exerted in here. Okay then! I'll show you how I buff myself up!"
Heading to a bench bar, Jacob smirked and took up position, putting on a nice, heavy 185 lbs on there, "And this is how Jacob Marshall gets his sweltering chest nice and pumped!" He was aware how corny that sounded, but he was getting way too into this - and not noticing the girls chatting amongst themselves as he started a set.
"Are you sure?" Britney asked Ashley as she watched Jacob do his exercise, "I mean, we don't know how far this stuff goes. And we don't even know if he's gonna age well. He's already 17. What if..."
"What if what if what if." Ashley responded coolly, and crossed her arms, "Don't get so caught up in what ifs, Brit. We've got the chance to really explore what this stuff can do. Just go with it. Besides, I don't think Jakey is gonna plump up or anything with age."
Jacob finished his set meanwhile, and got up, asking the girls, "So uh...do you girls wanna see any other exercises I do?"
Britney, looking to the side for a moment to quiet her objections, stepped up and said, "Well, you're already so sweaty, how about we get you nice and clean..." She showed the bottle of changing shampoo, gesturing upstairs toward the shower room.
Ashley added to this, "I mean, surely with that kind of an amazing body..."
Jacob however needed little prodding to get him to agree. He grinned, figuring out what the girls wanted, or so he thought. He stepped forward and put an arm around both of them as he did, "Well, that stuff seems like it'd just get me all dirty again...ah well, let's go." He didn't know why he was so unsure - two young women wanting him shirtless and then exercising and then a trip up to the shower room? It was clear to Jacob that this was set up for sex. And he was not the sort to turn down a torrid session, especially when his parents were away...
As they entered, Jacob wasted no time in removing his clothes, making both Britney and Ashley comment and whisper about his physique and good looks, and he outright flexed his glutes as he turned to head into the bath. It was time to see what would become of him...
