I am very happy for all the 30-year-old alpha males who are pumping up their muscles and telling stories about their dashing youth. Seriously, dudes, you look pathetic.
I remember my first sex very well, which happened even at a more tender age than Eric's (I was 15, my girlfriend was 16). It was very awkward, stupid and hot. Any virgin guy of 15-18 who sees a naked girl will be stupid and slow, this is completely normal. And if this story is about incest and about an even deeper personal connection between the heroes, then this is another reason why he holds back so much. It is not so easy to fuck your own sister, even if she wants to.
The only element of unreality in this story is that they were actively petting and teasing for 3-4 patches, and therefore Eric's reaction may seem a little strange. But then again, I have no problem - all guys are slow and stupid the first time, if it was different for you, then you are either a liar or a unique individual. We have dozens, if not hundreds of games about a not very smart main character who simply uses his impudence and luck to fuck the whole city/dormitory. So I am glad that here the main male character is an insecure teenager. True, I agree that he lacks a little charisma. Maybe after the first sex he will behave a little differently. I would not want him to lose this caution, romanticism and tenderness, but maybe in a normal situation he will behave more relaxed and attractively, that would really be nice.
Well, as a person who loves foreplay, I was given a lot of that here and I am grateful to the author. Although, if he wants to add more petting in the future, or rimming in both directions (Eric has the same juicy ass as Lina), then I clearly won’t be against it.
