Mind Blown

"Wait, what?" Poppy's big doe eyes stare at me in confusion, she seems as shocked as me that I'd propose such a thing. Even now, I'm not sure why I did, but... I don't want to take it back.

We sit up as I meet my sister's unsure gaze with determination. "I mean it. Let's date, let's have romantic evenings, walks in the park. Let's be a couple." I double down, taking her hand. Making it perfectly clear that I'm serious.

"What about the others?" She asks me, looking down at our interlinked fingers. Does she really not think that I'd commit to her?

"I'll call it off, if you want to be monogamous, then I'll tell them I can't be a part of it anymore." I answer with complete sincerity. Poppy's my priority right now, if she's not okay with the whole thing, then it ends.

My sister looks back up to my eyes with an expression I haven't seen on her face before. "What if I didn't want you to?" She asks blankly. I can't say I expected to answer that question, and Poppy seems to understand it's not a question in need of answering. "I... I want you to keep sleeping with them... To keep fucking them... I've never felt the way I did yesterday, that passion, that closeness between all of us. It made me so happy, so don't stop doing it with them."

I should be focused on the obvious news that Poppy enjoys the thought of me having sex with our family members, but a more pressing question arises. "So... Are you saying yes?" I try to clarify. Poppy snorts at my question, trying to hide her adorable smile. "I need a straight answer, yes or no?" I grin, enjoying how awkward she's feeling.

"Of course it's yes, you meanie." She answers, pouncing onto me, falling into my embrace. "I'll be your girlfriend." She whispers in my ear. Those words should not be arousing, especially from my sister, but they absolutely are.

"So, it's like, Romans got married, but they still slept with their servants... I like that idea, like... They belong to you, and you belong to me." Poppy explains as we cuddle on the sofa. I wanted to know why she was okay with the idea of me sleeping around all of a sudden, but her answer just raises more questions.

"So... You're saying you want Rosie and Marie to be our sex slaves?" I joke, taking a mouthful of popcorn. I don't even know what film we're watching, doesn't matter really, it's just an excuse to eat popcorn. Popcorn's great.

Poppy giggles at my suggestion. "In a sense, I guess, I'm not looking to chain them up in a basement or something though." She responds. My girlfriend has some weird kinks, doubly weird considering she's still a virgin. I only became a degenerate after I first did it.

Our romantic evening is interrupted by Rosie's arrival, and she looks... Exhausted. She flops back into a chair, and I notice she hasn't even bothered to dress other than throwing on a robe. "That girl... Is insatiable." She groans. "It's like she's got infinite stamina, and an insane imagination, I'd never even heard of half the positions we did."

Aah, my sister walking into a room and telling me about her sex life with our cousin. I have a very normal life. "If you're tired, you know you don't have to have sex, right? You can stop whenever you want." I point out.

Rosie looks at me as if I've said the dumbest thing known to man. "Why on Earth would I want that? I'm not complaining in the slightest." She argues. Oh, I misread her bragging as a call for advice, that's on me. "Aww, are you jealous? Does big brother want a turn too?" She taunts me, undoing her robe enough to make one of her nipples visible."

You know, I know she's joking, but... Kinda. Poppy nudges me, giving me a sneaky smile. I know what she's got on her mind. "Actually, yeah, it's been a little while since I had my dick in your mouth." I goad Rosie, who seems surprised that I'd taken that bait... Pleasantly surprised though.

"Hmm... I suppose it's a good chance to show Poppy some techniques, if she wants to stay and watch?" She replies in her most sultry voice. "Or join in, I definitely wouldn't mind that." She adds with a grin.

"I'll watch. If I want anything else I'll make sure to speak up." Poppy answers coyly, it's kinda cute watching her banter with Rosie, especially when I know watching turns her on so much.

I beckon Rosie over. This'll be the first time it's been the three of us, at the very least, it'll be memorable.
