Tengoku de Akuma ga Boku wo Miwaku Suru - Vol. 1 Ch. 1

[Autenga]

Isle of the semen demons

 

[HartSkai]

It would be a fun twist if his sweetheart back home is also a demon bent on squeezing him dry but was playing a long game and is now pissed the boonie bitches are messing with her cum sack.

I think the girl from page 1 IS her. You have to be invited to come to the island and she seems to be nobility, judging by context, so it makes sense that she has enough pull to invite him directly. She was also in charge of showing him around all week.

Too many coincidences.
