This was a manga, but I heard the screaming ringing in my ears! Do Chokkyuu Kareshi x Kanojo is a rollercoaster ride I'll never forget. From the advancement of the main relationship to the introduction of Mako's sister's little crush, I loved this for all its glory. The sex jokes are absolutely funny. As someone who's already gotten tired of kiddie sex jokes, the jokes made in here are absolutely immaculate. Props to the author for blessing us with such throat killing humor. From almost throwing my phone onto the other side of the room with all the cuteness and hilariousness radiating from this manga, to smilingso hard my cheek muscles started to hurt, I fully recommend you read this. It's a very good read, I promise you.
