Recently, My Sister is Horny

“Mitsuki, you really need to try harder!” Hiyori pouted, floating over the girl lying on her back. “Oniichan is going to fall for that stupid top-heavy woman unless you start putting out some more sex appeal,” the ghost whined.

Mitsuki rolled over, puling her blanket up. “I’ve told you already, I don’t want to seduce him!” she cried softly. “Will you leave me alone? I have a test tomorrow, and I need to get some sleep.” Ever since the ghost had shown up, her entire life had been way too complicated. Getting a new family was hard enough, but Hiyori was making everything a hundred times harder.

Hiyori suddenly yanked the blankets off of Mitsuki. “Well, if you need help, I know a trick,” she said, drifting down. She slipped a hand into Mitsuki’s pajama pants. Before the living girl could complain, Hiyori kissed her neck softly. Her breath hitched, stopping her words before they could form.

With her ghostly nature, Hiyori’s fingers could phase through the chastity belt and directly touch Mitsuki’s quim. Her long, slender fingers began to slide along Mitsuki’s outer folds as she kissed along her neck up to her ear. Mitsuki struggled to resist the building pleasure, but as Hiyori’s fingers brushed against her clit, her resolve evaporated almost instantly.

“If you would do what I suggest, Onii-chan would be the one doing this,” Hiyori murmured as she nipped Mitsuki’s earlobe softly. Mitsuki moaned softly, not able to think of anything to say, her mind already clouded with pleasure. Whenever Hiyori played with her like this, all her strength disappeared so quickly that she couldn’t do anything.

“Of course, he won’t have nearly as much interest so long as you have such tiny boobs,” Hiyori complained, unbuttoning Mitsuki’s shirt with her free hand. Cupping one of the small mounds, she gave it a soft squeeze, earning a whimper from the dark-haired girl. Pulling away from her ear, Hiyori moved in and took one of Mitsuki’s nipples into her mouth, gently sucking on it. She sped up her fingers, stroking Mitsuki’s clit harder and faster.

Mitsuki writhed, panting with every caress as Hiyori kissed her way across her chest. As soon as she reached the other breast, she latched onto it the same way she did the first, moaning a bit as she sucked. Mitsuki could feel herself reaching the edge. As much as she hated being stuck with Hiyori possessing her whenever she felt like it, and all the times that she ended up in strange positions with Yuya, she did love how good this felt, and...the times that Yuya was nice to her were wonderful as well.

She came a few seconds later. “Onii-chan!” The word slipped out so softly that she almost didn’t catch it.

“Ah, you're starting to fall for him, aren’t you?” Hiyori asked, releasing the nipple from her lips as she pulled her hand away.

Mitsuki blushed brilliantly. “Sh...Shut up!” she yelled, pulling the blanket over her head again, tears welling up in the corners of her eyes. It was only because Hiyori kept going on about him all the time, that’s why she had said it. At least that’s what she told herself as she drifted off, blocking the ghost girl’s taunting out...
