As Jon, Karyn, and Sarah were about ready to head upstairs, Jon's mom asked Sarah, "Are you ok, Sarah? You seem much quieter than your usual bubbly self."
Blushing anew, Sarah glanced at Karyn again, and said, "I'm fine. I'm just a bit distracted by a test I've got coming up. I was hoping that Jon and Karyn would be able to help me with it."
"Ok, well, why don't you three go upstairs and study, then. We'll try to keep the noise down. You got that, Mikey? In fact, why don't we go to the park, Mikey. Do you want to come, Zoe?"
"God, no! I'll stay quiet in my room, though," Zoe replied.
Mikey was thrilled with the idea, though, and ran to the door to get his shoes on. "Are we going now, mom?"
She chuckled to see his reaction. "In few minutes, Mikey."
"Ok, mom. I'll be waiting out front."
Jon looked up from listening to this to notice that neither Karyn nor Sarah had moved. "Ok, you two. Let's go upstairs." So saying, he nudged Karyn towards the stairs. He was about to nudge Sarah as well, but she immediately followed behind Karyn, her eyes locked on Karyn's butt.
Seeing this, Jon grabbed her as she went to go past him, and molded himself to her backside, matching her stride. "So what are you so fixated on, my pretty?"
"She's so gorgeous. Especially in that outfit. Can I get one of those?" she whispered back.
"What does it make you want to do?" he teased her further.
"Anything. Just imagining myself in one of those has me wet enough to fuck a horse," she replied, huskily.
"That could be arranged."
"What?!?" she shouted back, turning around to face him.
Karyn turned around to look down at them from the top of the stairs. "What are you two talking about?"
"Sarah was just admiring your outfit, Karyn. And wishing that she had one of her own. Or would you share yours?"
Sarah had turned around while Jon was talking, and walked up to Karyn. She reached Karyn just as Jon started the last sentence. As he said it, she wrapped an arm around Karyn, and reached down with her other arm. She put three fingers directly into Karyn's crotch, whispering, "I was just telling him that I'm just as wet as you are."
Karyn's arms went around Sarah, her eyes closed, and she moaned as she felt the fingers enter. "Oh! Don't do that out here."
Stroking her fingers a couple more times, making sure to rub Karyn's clit, Sarah asked, "Are you sure about that?"
Karyn's arms tightened at that, but her legs went almost limp as she leaned into Sarah and climaxed. Fortunately, Jon was right behind Sarah to keep them from falling down the stairs.
Reaching between her legs, he whispered in her ear, "If you enjoy doing that to her so much, I might need to let her do the same to you, later."
Once he'd rubbed across her pussy a couple of times, she reached an orgasmic high as well, and fell forward onto Karyn. When they didn't seem hurt, he gave them a minute to recover, then helped them up, and said, "Ok, let's see what this test is that you're worried about."
