Karen had been doing push ups on the living room floor counting to herself. Though her muscles ached, she continued to exert herself, pushing her matted bangs aside with determination. sweatdrops began to drip on the floor, reminding her that it was a particularly warm day today.
Karen had been wringing out all her reservations about her relationship with her brother Koyomi through strenuous exercise. She had felt affirmed in her choice to push her relationship with him. She loved him deeply after all, and was willing to fight for it with all her strength.
Her brother was not known for being the most athletic or disciplined, she had worries he lacked the strong will to face any obstacles they may face.
'Maybe we could start excersising together again, like a small date.'
Karen face becomes flushed at uttering the word.
'At least he doesn't lack any passion when he takes me to bed.' Karen giggled to herself at her own dirty joke.
'He certainly has more stamina than me there, I need to catch up!"
Hence, she began to train. Karen bends backwards and begins to stretch her legs.
As Karen continued her morning routine, she couldn't shake the feeling something was off. The entire time, Tsukihi's strange doll was propped up against a nearby wall and had seemingly been watching her. the bright piercing green eyes were unnerving her quite a bit.
"Tsukihi's doll...She is always leaving it around at strange places."
Karen stands up and walks over to the doll. She crouches down and pokes the dolls cheek.
The doll did not move.
"It is dressed really cute...I wonder if Oniichan likes this style?"
Karen takes a moment to dwell on the fact she had often seen her beloved Oniichan sneaking around whispering to the doll.
Karen runs her eyes over the young girl doll, unlike most dolls her skin feels really soft, and her hair feels like real human hair. Though her eyes are glossy and don't blink, they were striking. She looks like she could come alive at any moment.
Karen's eyes drift down to her thigh highs, which are snuggly pulled up to her thighs.
"Hmm.."
Karen lifts up the dolls skirt, peeking underneath.
"Panties!" She exclaimed in shock.
"Could it be...it's one of those strange love doll things I've read about on Oniichan's computer!"
Feeling incredibly curious, Karen carefully picks up the doll.
"Huh...It's suprisingly heavy...like a real body!"
Karen flips the doll over, as it flops and bends over, it's limbs sprawled outward on the ground. A mischievous smile forms on Karen's lips.
"Nishishi...What are you hiding underneath those panties!"
Karen tugs at the hem of the underwear and peaks inside.
She then immediately drops the doll.
"Ehh..It..It..It has a butthole!"
"Could it be...Oniichan is using this doll in such a way to relieve himself? He is the ultimate hentai!"
"Hey, what are you doing to my cute doll!?"
Tsukihi wanders in from the hallway, holding a shopping basket.
"Eh, Tsukihi...did you know it has a butthole?" Karen asks, pointing at the soft mounds on the dolls hindquarters.
Tsukihi walks into the room adjourned in her trademark yukata and kicks off her sandals, a shopping store bag hung from her elbow.
"Silly, that's where the batteries go."
"Eh?"
Tsukihi raises a finger to the confused Karen.
"I have a feeling she is one of those european dolls that are really fancy! there's times when I could swear it moved by itself."
Tsukihi looks towards the doll, who is face down on the ground.
"And it just came to me...maybe she just needs batteries!"
Tsukihi rummages through her shopping bag.
"I've tried small batteries and I've seen it's eyes twitch acouple times, but this time!~" Tsukihi pulls out of her bag a pack of large batteries.
"I'm sure it'll move this time!"
"A-ah...right." Karen replies.
As Tsukihi starts tearing the wrappimg from the giant batteries, Karen returns to her thoughts about Koyomi.
She knows of course that her Oniichan has always been really cool and popular, but it wasn't until recently she realized how many girls actually hang around him.
It began to make her heart sink at the thought that their relationship was only physical, and that he'd lose interest in her.
Karen couldn't help but begin questioning herself.
"Maybe my boobs aren't big enough, like Hanekawa-san's..." Karen places her hands on her chest, recalling all of themes of Koyomi's magazines hidden under his mattress.
"I'd hope I'm not boring him... was he unsatisfied with the last time?...maybe we should try something different."
Karen begins to brainstorm ideas while looking down at the doll, as Tsukihi grabs one of the batteries.
"Hey Tsukihi...Is the doll supposed to sweat like that?" Karen asks.
"I dunno" she said.
As Karen watched Tsukihi struggle to insert the batteries, Karen couldn't help but blush, remembering Koyomi teasing her with his finger before.
"Maybe he wants to do the same thing to me...with his batteries..."
Karen lost herself in fantasy for a moment, picturing her super cool Oniichan ravishing her once more, and daring to explore regions of her she herself never knew.
Karen lay upon a bed of roses, as Koyomi brushed her teeth ever so gently, the thought of her brother violating such a private space inside her thrilled her immensely.
"Ah Karen-chan," He said sweetly, "The brush really wants to probe another place"
"Eh? W-where Niichan?"
Koyomi lowers the brush, sliding the pointy end down her toned body, snaking down between her breasts and bumping over every abdominal muscle, he runs it along her thighs, diving in between them.
"N-niichan! that's-"
"But I want to put it there Karen,"
Koyomi grips the toothbrush tightly, and begins to press inwards.
"Uwaaaah!!~"
...
"Karen-chan stop drooling on the floor i can't concentrate!"
"Eh? Sorry..."
Karen wipes her mouth, embarrassed at her own perverted fantasizing. She would be willing to do anything for her Oniichan, but wondered whether such a thing would hurt.
"That doll sure looks uncomfortable." Karen said.
As she looked upon the doll, she couldn't help but wonder if that flat expression had somehow turned into a scowl, or if it was just her imagination.
