Today is your 20th birthday and you have decided to invite some colleagues from the company you work for to attend the birthday party. Among the colleagues you invited is your senior, a senior who always loves and protects you, but you are also a bit shy because of his excessive closeness to you compared to other juniors. A few hours later, your colleagues also arrived at your birthday party, although there were only 5 people including your senior because you were quiet and introverted, however you still had a great night with them.

Your birthday party finally ended in the middle of the night, and your coworkers decided to help you clean up. After a while, everything was done and your colleagues said goodbye to you and took a taxi home. You saw them off and then returned to the rented room, you were a bit surprised to see your senior, who was now drunk and sleeping on the floor, he had now taken off his clothes and was left wearing only his red underwear. You noticed he was still holding the glass in his hand and was sweating so you turned on the air conditioner in the living room for him.

Then you take a shower and then go back to the living room, you take your senior's clothes that are lying around on the floor and hang them on the clothes hanger then get on the couch, cover yourself with a blanket and fall asleep next to your senior on the floor. In the middle of the night (3am to be specific), you wake up thirsty and struggle to get up from the couch and go to the kitchen to get some water, however, your senior was gone and only the pillow was left on the floor but because you are both thirsty and sleepy, you don't realize it. As you reached the kitchen and opened the fridge to get a bottle of water, you heard someone groan and call your name, you look around and get extremely scared because you are ghost phobic.

You continue to look around then your eyes fall on the slightly open bathroom door, you trembled as you approached. When you reach the door and look through the crack, you see familiar red panties and you realize it's your senior, sitting in your bathtub and masturbating, in his hand is a picture of you and him together on your first day with him at the company. "Fuck... Oh... My lovely junior... My little junior..." your senior moaned while his hand stroked his cock while looking at the photo in his hand, he still didn't notice you standing in the crack of the door and looking at him.
