Hey I recently discovered this thread and thanks to that I finally tried
My pig princess. Initially I thought it wouldn't be as good but I was pleasantly surprised, so thanks a lot guys. I'm hoping to one day have a truly anal-only focused storyline that progresses slowly with a lot of training involved. The idea of slowly getting the body accustomed and little by little forgoing vaginal pleasure is extremely hot.
I wanted to also give my input on games with male anal focus, like
ToA and such. This games would merit being categorized as anal-only if the penis of the main bottom character is seldom interacted with. In ToA the MC can be put in chastity and/or being made impotent, making the anus the main source of sexual gratification. A game like
Star Periphery could be seen as an example of this but in this case (again this is personal opinion), the main fetish is futa-on-male and anal focus is secondary. If the male character had a vagina it would be played with.
Things like buttplugs, beads and all of those wonderful toys also improve the setting as you are using tools explicitly made for backdoor stimulation. Thanks for attending my Ted talk.
