“Oh. Sorry!,” said Katie. “Let’s go back now, OK?” Without waiting for agreement, she summoned the Device while still on her back, and pressed the STOP button. Then they were all back in their seats around the table. Katie looked at the display ... it read “IMAGE STOP 3:11:21”. Jason took the Device and plugged it into the recharger.
The three of them went out for the rest of the afternoon. They went for a walk in the mall, played some indoor miniature golf, had dinner early, and saw a movie that they later decided wasn’t worth seeing. Jason drove them Katie and Elsa back to their apartment.
They both invited him to stay the night. After all they had done together, Jason had no reason to decline. They watched some television, and finally, Katie and Jason headed off for Katie’s bedroom. Elsa followed. That made things a little sticky.
“Oh, Elsa, it’s you...,” Katie yelped, as if she didn’t know who was behind her. She turned around, just inside her room, holding on to Jason.
“Katie, you won’t mind, just this once? After today, I don’t want to be alone tonight. Oh ... if you DO mind, I’ll...”
“No, Elsa,” spoke Katie in a disappointed voice. She really wanted the time alone with Jason; but it was too early to make Elsa’s fears come true. She’d get over it in the morning. Katie would have Jason all to herself for a long time. “It’s okay. Let’s just not make a HABIT of it, okay?”
Elsa nodded. They all undressed themselves quietly. Jason got into bed first. Katie slipped in on one side, and Elsa bounced in on the other, wrapping an arm around Jason before Katie could. There was plenty of room in the bed.
“Elsa, are you ... Well, Katie and I have an SBC between us...”
Katie quietly answered Jason. “She’s got a general, Jason. She’s protected.” Katie hadn’t planned on Elsa actually having Jason, at least not in real life. There was something she didn’t like about sharing him in reality. She was having worried thoughts about Elsa’s intent.
Katie felt Jason’s hand on her breast. He squeezed it. He seemed very excited; she wasn’t, yet. There was a good reason for it; Elsa had one hand wrapped around his cock, which was growing at her touch. This delighted Elsa very much. She moistened him with her own juices.
Jason was putting his efforts into Katie, not Elsa. His hands found two pussies; Elsa was wet, and hot; Katie was warm, but dry. He got a finger inside Elsa, but he could only rub Katie on the outside, so far. She started breathing deep. She was opening-- he started a finger inside Katie, and she started moaning. It was intentional; Katie was letting Elsa know that Jason’s attention was on her. He slid his finger deep into Katie, rubbing the spot that made her come before.
