The faces in this manga never fail to make me laugh. Kind of reminds me of I Love Amy.
Definitely not the thing to say when looking at your.. Girlfriend?... Boyfriend?'s breasts.
I assumed them saying it wasn't as exciting as expected meant they weren't physically attracted to each other but like a page later that seems to not be the case? Eh.
Love how Hajime just assumes Sainami is some expert in lesbian sex.
