The Beautiful Genius-Level Girl Is Secretly A Masochistic Baby-Maker! (Patreon)

I was looking forward to posting this one! Saya Takagi is great, I love this busty teen to bits, so getting commissioned to do a follow-up to my earlier story featuring her was a pleasant surprise. 

With the previous chapter being fellatio-focused, this one naturally takes it to the next level, with yet more help from the dutiful Shizuka. If you liked the first one, definitely give it a look.
