I understand that folks voice frustration with the lack of sex, but that being said, it was not particularly advertised as vampire porn. Yes most of the VN on here are porn based, but a lot are a mix and a few are very slow burn with a payoff, and this happens to be a vampire novel based on some previously published lore.
We are guaranteed one more sex scene.... I doubt it will be an orgy, and I am not thinking that there will be much more than that one sex scene. That said, if you just ride this to where it goes, and save images to fap to or find other fappable (is that even a thing?) material for those needs and just flow with this, you will enjoy it much more I would wager.
Our MC is freshly (relatively) turned and yes by a super powerful vamp so he is in turn accelerated in his development. His actual desires (not necessarily the reader/player's desires) will eventually change such that sex on an occasion as a means to an end, or as an occasional activity with his lover will be a thing, but if you pay attention in the novel, even he thinks to himself that the blood kiss is much more intense and desirable than sex. Yes, that does not mean it would be what you or I would want, but you and I presumably are not vampires. (if you are one, I volunteer for the embrace....just saying)
In any case, update is on track and soon we can see why Carmen looks like she was ridden hard or drained hard or whatever!
Peace
