Making a Call^'

Within the blur of rampant horniness, you knew there was something you had to do. You'd talk to Dave when you got back, but you couldn't leave things with Diane the way they were. You loved your sister and wanted to make things right, and maybe sow some seeds. Carefully getting out of bed so you didn't wake Greg, you grabbed your cellphone and went into the bathroom.

Taking a deep breath, you call Diane.

The phone rings twice before your sister picks up.

"Hello?" Diane picks up, sounding a little tense.

"Hey, Di. I..want to apologize."

That seems to take her offguard. "For what, Suzy?"

"For being a hypocrite for years. I've realized some things, things I'm going to have to work on. Specifically in regard to my relationship with Dave, but I wanted to set things right with you first."

"Suzy..what are you saying?"

"I'm not mad at you , or Dave for that matter. I mean, throughout our lives sex had always been a casual thing that had nothing to do with love. Making Dave off limits to you was frankly unfair," you confess. "I love you, Di. You're my sister and closest friend, I shouldn't have done that to you."

There's a pause, then a slight sniffle on the other end. "You mean that, Suzy?"

"I do. Clearly Dave and I need to talk when I get back from this trip about what our relationship's going to be, but I didn't want my "do as I say not as I do" crap to come between you and I," you say sincerely.

"Thank you, Suzy, that means a lot," Diane replies gratefully. "So wait, you said you're not mad anymore. Does that mean..?"

You find yourself grinning. Making up with your sister makes you feel like you have your oldest co-conspirator back. "I want you to keep having sex with Dave."

There's a pause, and then a gasp. "Did I hear you, right?"

"I know, but after I got past the hypocritical anger and really thought about it, it turned me on so much knowing you two were fucking," you confess, your voice getting hoarser.

"Holy shit you're serious!" Diane sounds surprised, but then there's chuckling. "I've always suspected you had a bit of a voyeuristic streak."

"Look who's talking!" You laugh back, your old bond returning as if it had never been strained. "What about that time I saw you peeking on me and Malik Jeffords back when I was home from college?"

"You were in the living room! I'm supposed to not look," she shot back, also laughing.

"You were supposed to be in school," you counter playfully.

"I was sick," Diane countered in turn. She stops, turning serious. "I've missed this."

"Me too."

"So I can really keep fucking Dave and you won't be mad?" Diane asks one more time.

You smirk. "Not only am I serious, I would consider it a solid if you could record some footage of you two in the act and send it to me so I have something to masturbate to."

"..fuuuuck that's hot." Apparently your little sister was more like you than you thought. "Wait, this isn't some divorce trick to use on Dave is-"

"I swear on Grandma Aggie, Di." Agnese was your maternal grandmother. You couldn't say "Agnese" growing up, so she became "Grandma Aggie," a tradition that carried on with Diane. You both loved her dearly, and saying "I swear on Grandma Aggie" had been the strongest form of promise between the two of you since.

"Wow," she sounds like she's still processing, but then you hear mischief in her voice. "I'll see what I can do for you, you big perv."

You giggle a bit. "Love you, Di."

"Love you, too, Suzy."

You hang up, smiling wide. Not only had you patched things with Diane, but you feel like a whole new facet of your sex life has opened up.
