Onee-chan To Asobou [English], by Ginshari

Meh. Shotacon. If it weren’t for that, I’d have been loudly whooping, the female MC (a babysitter) is smoking hot, her confidently horny gazes were great, and it’s an uncomplicated introduction to sex, simple fap’n’go.

The rest is in your hands, me, I’ll just thank Bango, Eno and Vilis, from Hennojin Scanlation, and finish preparing that post ^^

Edit: as Loplop mentioned in the comments, the girl looks a bit like Utaha, from Saekano ^^

And now, the download & gallery links

Open the Complete Pictures Gallery

Smaller version incoming!
As of usual when ☑ the images are in high enough resolution and ☑ the archive is quite big for its number of pictures, and ☑ it offers a significant gain, and ☑ I have enough time to do it, if it may help, I’m offering you a smaller version, in which I resized the images to lower-standard 1600 px resolution. Originally, the images were within 1% variations around the usual 3000 px high res figure.
The zip shrank from 61 MB to 11 MB.
Personally, I prefer it for reading, and it takes less disk space.
