Possible but there's no context and its just 1 page so unless 23 clarifies we'll never know
And 23 has not even given them proper names let alone whether ahoge is a futa or not.
I think he prefers to let some things be indefinite about this couple. Some artists feel they spoil things by giving full details and they want to leave some things to the imagination.
Look guys. Look. Seriously. I know you're going to vote this down because people get crazy about this. But you can't freak out every single time this happens.
I realize you want to project your own narrative onto this little "story" here. But please realize a few things
1. It's not like this is an official story or series. Let's be honest here. The only real continuity to this "story" is that they got married at some point and ahoge girl is really horny. They might work together. That's the "story" so far. It's a bunch of mostly out of context unrelated pictures. There's nothing official. Nothing concrete. These are just his two favorite characters. That he likes drawing in sexy situations. They don't even have names we know next to nothing about them. They've only spoken like twice.
2. You guys don't know the full "story" that IS there. Many guys have been resistant to any interpretations like an open relationship, pornography(a very real possibility considering that dsg appears to be an erotic model of some sort) or
ahoge girl being a futa when this artist has done a ton of futa work. Inckding with a very similar couple. You have no basis to be so resistant to plausible explanations and really, no reason.
3. This "series" is very clearly the artist projecting his own imagined fantasies of dsg using ahige girl as a surrogate. This series is about drooling over dsg. That's the main objective. Always has been. There are some extra cute moments there too but it's very clear.
4. Earlier he wrote off similar things as simply a fantasy or side project. It may be the same here. It may not disrupt the canon at all. People make fanfics and doujin where characters act out of place. If you want to preserve the "canon" just think of it as the same.
There really is no basis to be getting so angry and defensive.
I enjoy the interactions of the couple too and the sweet moments. But you gotta be more realistic in how you view this.
