Saki-chan wa Konya mo Peko Peko Manhwa (Uncensored)

Saki-chan is a beautiful young woman and just a little naive. She may seem harmless as she wanders the streets, but beware–she's a brand-new succubus who thrives on the lust of men! She’s just... not very good at it yet. When she finds herself with an opportunity to move in with a 30-something man who's never slept with a woman before, she takes it, just like she'll take him! Er, eventually.
