⛔Wouldn't recommend to people either under the age of 16 or people who get butthurt by dirt talk, rare pairs, use of the word "cock", sex, gayness or anything like that lmao⛔
*This fic DOES contain SEX, SWEARING, GRAPHIC DETAIL, yaoi (boyxboy) and Oikawa is 16, Akiteru is 25. Please do not read if you're uncomfortable with the topics.*
Oikawa Tooru is in love with his teacher, Akiteru Tsukishima. It's not exactly unknown, to him, nor to anyone else. However, the one person that doesn't seem to know about Oikawas feelings is the person he wants to tell the most, Akiteru. Oikawa thrives for his sensei's attention, whether it be answering questions in class, or asking for help when he clearly doesn't need it. Oikawa wants it, he wants his senseis attention. He wants to hear his voice, he wants to feel his eyes on him, he wants to smell the scent of his sensei's cologne which he wears everyday. He wants Akiteru, in oh so many ways. One day, Akiteru finds out that Oikawas grades have been slipping and asks him to stay afterschool to discuss what's bothering him, Oikawa protests that there's nothing wrong but soon realises that this could be an opportunity to spend some more time with his Sensei. Oikawa is looking forward to it. Because this time, he's going to get his sensei to listen to his reasons..in more ways than one.
