Saikyou Controller (“Most Powerful Controller”) [English], an hentai doujinshi parodying the Bodacious Space Pirates series, by Numahana (circle Aroma Gaeru)
Ririka, a female character from Bodacious Space Pirates, and a male colleague, become sex buddies. She reveals to him she is not just your average MILF loving dick, but a tigress in bed, enjoying gangbangs. The young man sees no issue with it, his sex drive allows him to keep up with her: boyfriend GET! ^^
And then the drawings. Daaaaaaaaamn they were hot. A juicy middle-aged body, thick eyebrows, decent enough art, it was nice =)
We owe this one to N04h, Pr1de, PureEnergy and Red_Piotrus, thank you!
