The pill (Stickyfun/ShashaWraight )

Mika fidgeted as she lay in her bed, tossing and turning as her tail twitched. "Nnnngh...." She fidgeted again and rolled over onto her side, turning her back on the bed of her twin on the opposite side of the room. Earlier in the day Mika had been talking with her friends about the upcoming exams....and then Mika had mentioned she was worried....after all, her twin sister had been the one to get the brains in the family. That was when her friends had given her the pill....they had said it would help her study, help make it easier....but after she had taken it Mika hadn't felt any urge to study....if anything a different urge had started to kick in.

If anything....Mika would have to describe it as.....heat. "Nnnn...." She let out a soft whimper again. The more she fought it, the stronger the urge became. The longer she left it, the more she wanted to do something to satisfy it. If she didn't do something soon her body felt like it was going to just....
With a slight hiss she just couldn't take it anymore, her hand immediately moving down to her nightgown, slowly lifting it up. "I can't....I can't take it anymore...." Either forgetting or simply not caring about the consequences anymore, Mika moved her hand slowly, feeling her fingertips touch against her wet pussy lips.
The instant she touched herself, she couldn't help letting out a loud gasp.....the sensation had been....incredible! Like nothing she had ever felt before!
With a mew of pleasure, Mika slowly slid a single finger inside of herself, biting her lip to suppress the moans of pleasure as she began to finger herself.....but god it just wasn't enough......the touch of her own fingers....it just wasn't going to satisfy her...

Shasha came into the room after spending the day at the library and put her bag down then saw her sister and blushed a deep, deep red. "I-I-I'm so sorry sis." Shasha said turning around about to head out of the room.

Normally Mika would've freaked out upon hearing her sister entering the room whilst she was doing something like this....but right now....oh god the words just came out of her mouth before she could even think about them. "S-sis.....h-help me!" Mika mewed loudly in pleasure, arching her back a little as she pushed a second finger inside of herself, whilst her other hand was grasping and squeezing one of her breasts through her nightgown. "I....I can't do it....by myself...."
