Yang Pov
It was a sunny day at Beacon but things weren't so well. Yang Xiao Long was looking for her boyfriend (Y/N). She wanted to ask him if he is willing to take her for a date, but he was nowhere to be found. While walking down the hall she came across her little sister, Ruby Rose.
Yang: Hey little sis, have you seen my boyfriend (Y/n)?
Ruby: No, I'm afraid not. The last time I saw him was in his room. He told me he was out training with his master and him didn't tell me where he was training. But he said he will be back tonight, though.
The blond haired huntress became disappointed after hearing this. She sighed and headed to your room. She arrived in front of the door to her boyfriend's room. By the time she opened the door she couldn't believe her eyes. The room was a mess, the bed sheet on the bed was also a mess there is a computer on the desk which is on screen saving mode. Also the there is an HDTV and a game console on a stand next to the desk.
The huntress entered in and look around her boyfriend's room. While she was doing that she notices something under his bed that looks like a shape of a rectangle. She went to the side of his bed, look under the bed and pulled it out. She got back up looked at what she was holding. Her face became immediately red and had a massive nose bleed. The item is was holding was a magazine and in front of the cover was a woman, wearing nothing but a crimson bikini, on a beach, kneeling on her knees and flexing both of her arms. What caught her Yang's attention wasn't just the woman's E size breasts, but how muscular she was. She began to realize that this is a female muscle porn magazine.
Yang's mind: "Why the hell would show have this?"
Yang opened the magazine and continue to flip each page. As she continues to do that, her body becomes an and her face is still red. Then suddenly she stopped the magazine was dropped from her hand. She grabs the sides the side of her and began to thank what to do.

The blonde haired girl opens the web browser. She then went to browser settings. When she opened history, she was shocked by what she saw. The browser's history was filled with websites and searches such as "Muscular Girls" "FMG" "Sexy Female Muscle".
She closed the browser and turned the computer off. Yang started to think what she should do. She could punish (Y/N) for this type of action. But if there is a way to make him more sexually entertained. Yang smiled as she likes the idea. She walked inside his closet and closed the door and waited.
