I was surprised not to find more from this artist on here. This CG set is available on their fantia by subscribing to the free plan, I downloaded and renamed all the individual images myself. All files are identical to the counterparts in his post, I do not know why there's such a striking difference in the final image of the texted and textless variants.

'Mokou give Keine a BBBJ' is the English name the artist themself chose for the set. I am not subscribed as a paid member yet so I cannot confirm, but I suspect the paid plan has a full translated version of the set (there's a English sample in the post).

Support the artist if you enjoy their work - just a subscription to the Free Plan helps even if you're unable/unwilling to support them directly.
