I laughed when she mentioned that her tits are so big, people believe that she's pregnant.
Well, this is good smut. Even though her boobs are cartoonishly large, she does have a nice face and the art is good. Glad MC found a girlfriend instead of somehow making the relationship between him and the neighbor work out. The affair wasn't meant to be long-term.
Also, funny how MC's mom knew about it but kept the information to herself. Can't blame the son's tastes, eh?
