This is the type of gooner bait i can get behind honestly.
MC that doesn't fuck around and disregard the feelings of the sisters, is honest with his own feelings, and isn't a giant pussy about it all. He properly reciprocates their feelings and his own possessiveness over them is refreshing as fuck. None of this "They are way too good for me" bs. His desire is to rise to the occasion and show them how much he wants them and cares for them.
This is definitely a "junk food" story, but damn is it tasty.
