You tell her you genuinely want the foursome.

You stroke her back reassuringly as you whisper, “You want to know what I want to do tomorrow?”

You feel her nod in assent. You whisper closer to her ear, making your warm breath tickle her lobes, “I want to see you in your fuck-me dress sitting on a chair with your pussy spread out and ready.” Your hands slide lower to her ass. “Then I want to spend all morning teasing and eating you out, making you wet and begging for release. But I won’t let you cum, oh no. I’m going to wait till Jakob arrives and then proudly offer your pussy to him. I want to see you cum all over his cock, I want to hear you moan his name, and when he’s filled you up: I want you to show me your slutty pussy with your new lover’s cum dripping out of it. This is my answer, love.”

You hug each other tight, her relief palpable. “I love you babe,” she whispers. “And that was really fucking hot. Do it to me please,” she begs.

“I’ll try my best. Also you really think I’m asshole enough to make you choose between your best friends or me? You guys have been close for so many years. It’s rare to have friends like these. All I have is Robert and we aren’t even that close.”

“Now if you had been a smart boy and experimented with him back in college,” she teases, “you two might be a lot closer now.”

You pinch her ass, making her squeal. “I liked fucking Sarah and I liked fucking her in front of you. I want to experience it from your end now. Tomorrow I won’t be thinking ‘My girlfriend is fucking another guy’, I’ll be thinking ‘My girlfriend is getting a great sexual experience’. And that makes me happy, and horny.
