My super clumsy and shy sister recently got a boyfriend, and just when I thought things were looking up, she shocked me by asking if I could lick her 'there.' She had been refusing cunnilingus from her boyfriend because she was too embarrassed, but it seems like she can't refuse him much longer. So, she wants to get some practice in first. Unable to resist her desperate plea, I licked her there. She felt it so intensely that she pinned my head down with her feet like a mantis, grinding against me as she came over and over! In the end, she couldn't hold back anymore and wanted to insert a penis, turning into a complete slut!
