My breathing was fast as my sister and I exercised in the park. We had been at it for several hours and it was getting dark, so we approached a nearby bench to rest. I looked over to Lucy who was quieter than usual while admiring the landscape.
Her face was sweaty and I noticed how she was trying to catch her breath. With each inhalation our shared chest inflated. I could feel the subtle touch of our upper breasts against the lower ones in our sportswear. I looked at our legs for a second, slowly moving our right leg to collide our exposed thighs; The feeling was intoxicating.
A strand of Lucy's hair came loose from her ear, dangling between our faces and catching my attention. She looked incredibly sexy with her usual smile and happy vibe. I noticed the hot breath coming out of her mouth, forming a small cloud in front of her that brought back memories of other lewd situations. I looked away from her, trying not to make her uncomfortable as I felt her head turn towards me.
“Oh wow…” she said with a smirk. “…Is my sis getting horny?”
“W-...What?! No, I’m just… exhausted,” I replied in a flustered tone.
“Why do you always try to hide that from me?” Lucy asked, pouting a bit. “At least share what you were thinking so we can enjoy it together. Was it some mutant? Any pretty girls or guys?”
While talking to me, Lucy used one of our right hands to poke my cheek with a finger.
“She… yes, she was a mutant.”
"Oh yeah? And what was she like? What shape does her body have?” Lucy asked me curiously, crossing our legs as a sign that she wouldn't let me escape this one.
I sighed and looked into her eyes again. “She is a very happy mutant. She is almost always making jokes… she is somewhat perverted although quite clueless, and she has a pretty smile.”
I could feel at that moment how Lucy's cheeks turned red and how she swallowed, telling me to continue with her expression.
“And as for her shape, she has four breasts, four arms and… she has a twin conjoined next to her,” I said with a warm smile.
She looked surprised for a few seconds and then her smile turned a little mischievous.
“Heheh… have you gotten horny looking at me? You’re so narcissistic.”
"I’m not you though, you’re completely different from me!” I yelled to her, trying to defend myself.
“Physically I’m a faithful copy of your face and the rest of my body… well, it is yours too.”
“Yeah… but everything I mentioned about that mutant was her personality.”
“Aww, you don’t like my boobs then…?” Lucy said teasingly, using all four of our hands to squeeze our breasts.
“Y-Yes… yes I d-”
"Narcissistic!"
"Shut up…!" I groaned, crossing our arms while she laughed before she stared at me. “Anyways, you should wake up now…”
"Wake up?" I asked her in a confused tone.
“Did you really think I’d run with you until nightfall without protesting? You should realize this is a dream…” Lucy told me, holding my cheek. “You should wake up… Sophie… wake up!”
Her voice from the dream mixed with her real voice while I felt a hand slapping me softly on the face. I opened my eyes in surprise, trying to sit up on our bed and feeling Lucy control our body to keep us from falling.
“Good morning, sleepyhead,” she said while laughing.
I touched my face, somewhat confused. “Were… you controlling what was happening in my dream? Do you remember what it was?"
Lucy tilted her head, slightly confused by my question. “Are you still a little asleep? What the hell are you talking about, sis? I can't see your dreams, you know…"
I sighed and adjusted my hair as I looked down, noticing how we only had our panties on. “Yeaah I'm sorry… it just felt very real…”
“That's why I woke you up. It started to feel a bit wet between our legs,” Lucy said with a giggle.
“R-...Really?”
Lucy nodded several times. “Yup… so, the dream was about me and you got like that? What a perverted sister I have."
“It was you who teased me in the dream!” I said while covering our breasts.
"Oh yeah? Surely you got like that by staring at me and having depraved thoughts.”
I stared at her in shock and she started laughing. “See? I am right!" Lucy told me.
I blushed and looked away. “Y-...Yeah…” As soon as I finished the sentence, I could feel our heart racing and our libido rising even more.
“You're so cute when you react like that,” Lucy said in a much more affectionate tone.
“Cute? I think I just turned you on even more…” I replied as I looked at her again. Lucy just smiled, kissing me on the lips and holding my chin.
“You know… we could use our morning time efficiently…” she whispered, taking control and shifting our body towards the bedside table to open the drawer. Lucy took out a large dildo we stored there, sitting our butt on the bed again and holding the dildo in front of us.
“We could use this one again… last time was very memorable,” she told me with a flirty tone.
“You don't even need to ask…” I replied warmly, knowing it feels too good to pass up.
It didn't take us long to drop our panties and lie down on the bed. Without saying a word, the kisses and caresses became as intense as the libido that flooded our bodies. The dildo moved from one mouth to the other, then passed through our four breasts to reach our pussies, very wet and lubricated.
We stared into each other's eyes before slowly inserting it into our right pussy. We both opened our mouths as each inch entered, until our hand stopped.
“I-I think… that's it… right?” Lucy asked through our shared panting. I nodded in response. “Yes… I think it will hurt if we go deeper… it's too big!”
"Let's continue then..." Lucy said before she started kissing my neck and moving the dildo in and out. It didn't take us long until we reached an orgasm and moved the dildo to satisfy our other vagina.
Minutes later we were lying on the bed, exhausted with shaky legs as the sheets were damp from our fluids. We both started laughing, still casually playing with our breasts.
“It's a good way to start the morning,” I told Lucy with a slight giggle.
“Yeah… I think I should wake up first and control your dreams more often,” she told me, laughing.
“W-Wait, what?! Then can you control my dreams after all?” I asked in surprise.
“Ehh… well, not exactly… but I do admit that your dream turning into a wet dream was a little my fault,” Lucy said, scratching her cheek.
“Ohh… I think I understand what you mean. So… our libido was not because of my dream, but my dream was because of our libido and because of YOU,” I said before winking at her.
“Well… yes, I admit I’m guilty,” she replied as she moved a hand toward our groin. “Maybe I shouldn't have shared that secret. It was a powerful tool to have mornings like this.”
“You know there is no need for secrets between us,” I said in a very tender tone.
She leaned her head towards mine, resting against me. “You're right…”
Her hand began to play with the lips of both of our vaginas.
“You know… in my dream we had exercised until nightfall,” I told her as I helped her play with our body, caressing our legs and breasts.
"Oh really? And you didn't realize it was a dream? I wouldn't have allowed you to do that."
“Haha… the Lucy from my dream told me exactly the same thing,” I said as I kissed her. “Ready for one more round?”
"Of course!" Lucy replied happily.
