It's not so much that it can happen, it's more how this author portrays it as: this is what to expect. I'm not sure if I'm wording it well. Like the fact that they do do fingering but he still tears, the fact that he says it hurts but the other guy still continues, even down to the cover "you expect me to be nice for your first time", it's clearly more of a sadism fetish and "pain experienced with the first time" than "dumb kids being dumb". If the seme had acknowledged he fucked up and would do better next time, it might have come across less as that and more stupid kids being stupid. The fact that the uke immediately forgave him and they just immediately move past it, it was clearly not meant to be that deep and is just fetish content.

Yikes. Ya'll you should not bleed from anal when prepped and done properly. This story seems to be applying the fetishizing of the breaking of the hymen (which is also a myth, the hymen comes in all shapes and sizes, can be comfortably stretched, and potentially broken before the first time) to anal, which is fine ig if that's what you're into but it's not what should be expected irl. My first anal was good and comfortable but I've also been raped anally and bled from that for several days. It's all about the prep (also exhale on insertion and relax your hole).
