"Let's do this," Louise said, smiling. The feeling between her legs wasn't going away any time soon. There was only one way back to earning her laser focus again. Louise leaned back so she was on her back, spreading her knees apart even further. Tina knelt forward until her lips pressed against her panty-covered mound.
Louise gasped, then bit her lip. The feeling of her sister's lips against her sensitive clit, even though her underwear, was indescribable. She had rubbed her pussy before - what little girls hasn't? - and she even experimented with putting things inside. When her parents and siblings weren't around, she even liked spend extended periods of time sitting atop the washing machine. But lips? A tongue? There was no way to simulate that and it clearly showed.
Louise reached down and grabbed two handfuls of her sisters hair. She pulled, bringing Tina even further into her crotch, until her nose was smashed against her clit. Louise let out a soft yelp at that feeling. She felt like she could cum just by that alone. At least she did until Tina opened her mouth.
"Lfheeh lffmh mfh gfh."
"What?" said Louise. She looked down to see Tina with a mouth full of Kuchi Kopi panties and pussy. "Oh, sorry." She released Tina slightly, letting her back up a half inch so she could speak.
"Louise at least let me take your underwear off," Tina said, "I can't properly do this with that in the way."
