[Kutsugen Kanna] Pen Saki no Koibito [CulturedCommissions]

A shy schoolgirl with a daring secret finally confesses to her bewildered boyfriend, whispering that she wants him to use her precious pencil on her in ways no proper gentleman would ever imagine. The blushing teen eagerly spreads her stockinged legs and squeals in delight as the well-endowed writing instrument is thrust deep against her cervix, her helpless partner caught between his desire to be a gentleman and her insistent demands for more. Dripping with sweat and overwhelmed by a dizzying climax, the petite lover collapses into bed, thanking her "Yocchan" for indulging her wonderfully unhinged fetish.
