I like that a lot that's quite a lot of action. I did not notice it on old gurochan.
It would be better if you don't mention those second thoughts he is experiencing how he loves her sister and how he will miss her etc because that ruins the fun of the story.
In all that farm play I expected that she will lay some eggs after all :) and that woud be also fun, but looks like she decided not to on purpose to get snuffed :)
