Rikka and Lucy

* The Connected Space.

Darkness envelops you. You can't see anything but a never ending emptiness spanning all around you as your body floats in a sea of nothingness. A squeezing **** flows around your floating body making it difficult to breathe. It's unnatural touch cools your skin that draws out goosebumps over your body.

"Greetings once more, host." A strangely familiar synthetic woman says through the void. You spin, at least you think you do, trying to determine the source of sound.

"Where am I?" You ask as you settle down your movements.

"Do you need me to remind you?" Taking your silence as confirmation the voice continues. "You are joined with version number three-zero-nine-seven. Prototype-"

"Rikka?" You interrupt. "We're in the connected space again?"

"Correct host. Due to your sleep pattern our meetings are not aligned from the initial connection. During our merge I will enhance your body, these enhancements take place every twenty four hours from the initial connection. However, I will have to take your desired input into which enhancement to pursue ahead of schedule." Rikka explains.

"You're getting weirder Rikka, which I suppose isn't saying much as we've only met twice now." It sounds as though she giggles at your words. "So I have to pick a, what? An upgrade and then I'll wake up?"

"Something to that extent, yes host."

"What are my choices?" You ask trying to shake the discomfort of the unnatural touch that still chokes your body in a cool blanket.

"During the first enhancement point you are limited to a smaller choice. I can increase your strength per muscle mass, I can increase the rate at which your synapses fire, or I can increase your oxygen intake."

"Huh... I want to keep everyone safe so maybe the increased strength?"

"As you desire host." Rikka's voice sounds closer. "This is going to feel uncomfortable. Sorry." Wow, she totally sounded like a pers- Your thought is cut short as an intense heat floods your body starting from your right hand. You look down to see seven glowing holes where the pain is concentrated.

As the pain fills you a bright light comes hurdling towards you. Just like it did last time. Realising you're about to wake up you call out one last thing through the pain. "Stop calling me host! My name is Michael!"

* Back to reality.

Your body tingles all over as a gentle warmth spreads from inside of you. You body feels sweaty despite not being covered. Not covered? You slowly open your eyes which doesn't emit any pain. Your surroundings start to fill into place as you are able to see. The first thing you notice is the worried face of Lucy looking down on you, which is followed closely by the feeling of her soft thighs on the back of your head and her large melons just inches from your face.

"Shh." She strokes your head as she whispers. "It's okay. It was just a nightmare. You're safe here at home brother."

"What nightmare?" You whisper back.

"You were thrashing and muttering in your sleep, it looked really bad." Her expression softens. "But if you're saying that you weren't then I'll believe you."

"I wasn't, honest." You look to your side to see Sam still sleeping under the duvet you were sharing. "Wait a minute, what are you doing in here anyway?"

Lucy's eyes half close as a wide smile falls over her face. "Well after my dear brother held me down and made me experience the pleasures of the flesh, I felt obligated to return the favour as a good. Little. Sister..." Her head stroking stopped as her hands redirected themselves down your torso.

She parts her soft thighs, letting your head rest against the bed once more, as she crawls down the bed kissing your body as she went. You dick starts to strain against your underwear as Lucy draws near with her kisses. She keeps going and turns around so she's lay between your legs and begins to caress your thighs. "Just remember big brother. This is to show you how much your little sister loves you."

She gives your cock a kiss through the underwear before peeling it down. Your hard mast hits Lucy against the face which makes her eyes go wide and mouth part slightly. "Oh wow. I always wondered what made brother big." Her warm breath makes your cock twitch that draws a quiet giggle from her mouth. She takes your large hot meat in her small soft hand and starts to slowly stroke. "Try to keep quiet Michael, it'd be a shame if we get caught." With another giggle she takes your head into her mouth, parting her supple lips.

Her tongue circles around the head letting drool roll down that she uses to speed up her hand strokes. Once your cock is covered by her spit she starts to move her head to take in more of your meat. "Oh Lucy. You feel so good right now." You whisper as you let out a deep breath.

She takes your words as encouragement and removes the hand from your cock and places both of them at your sides, she uses her head to move down your length. Audible slurping sounds emit from your sister's mouth as she bobs her head down your thick meat. Occasionally she moans in delight as you hold her head with one hand. "Yes sis! Shit, your mouth is good." You moan louder this time. She looks up at you with what looks like a smile before focusing on your hot, wet shaft.

The all too familiar sensation of cum building informs you of the end to your pleasure. At least for tonight. You press her head down to increase the tempo which make her sloppy slurps louder as well. "Lucy, you're gonna make me cum. Keep going." You roll your head back from her oral stimulation's. She pulls her mouth off your thick cock and switches to jerking you off at a fast pace.

"Unless you want to make a mess brother, you better cum in your sister's slutty mouth." She takes you back into the warm cove of her slimy tongue that coaxes the cum from your balls.

"Yes. Yes. Lucy you're going to make me cum." Your cock starts to throb in her wet mouth as you grab her head with both hands and hold her steady. "AH, swallow my load sister." She gulps down three mouthfuls as you paint the inside of her mouth with a torrent of hot cum. You release you grip while your cock still pulses the last ounces of cum out. Lucy dutifully keeps her supple lips sealed around your meat as she sucks and swallows every last drop.

She eventually lets your cock go with a bit of drool hanging from her mouth. She giggles, "brother's cum tastes yummy." She crawls back up your body and lies down on top of you. "Are you satisfied Michael?" You kiss her forehead as she snuggles into you.

"Yes, I'm absolutely satisfied. I love you lil sis." You close your eyes with a smile on your face and a warmth flowing through your body.
