Things were going swimmingly for the twins. It had been almost a week since Katie’s pool party, and they had not only forgiven each other, they had launched a full-on sexual relationship. Honestly, it was more like a deal, and on Monday they had discussed the terms:
“I think we should just be naked all the time,” Katie suggested, “it keeps me in the mood, and I just like looking at us.”
“Agreed, most of the time, except for when I want to dress up before we do it,” Karen rebutted. “Also, I think each of us should initiate whenever we want it, no holding back.”
“I think so too,” Karen said, “but you’ve gotta give me at least 15 minutes after sex before initiating again.”
“Can do, but I get to decide whether you cum in me or on me, and no mouth kissing. We’re not lovers, just sisters who fuck,” Karen stated, very matter-of-factly.
