Mhmm, Nikodem is going to go crazy with this

Saejin looks for Nikodem's contact, and starts typing a message "Hey, Nikodem, I'm Saejin, the math teacher... Mhmm, I was checking the exams, and I saw that you need some private lessons"

She sends that message, but then the best part comes, she attaches the naughty pic, and types another message "I was also organizing some things and found my old uniform from when I was a high school student, I think it's a little small on me~"

Finally, she types the last message "Come to my house, big boy, I bet you want me to give you some math lessons and maybe something else, I'll be waiting for you~" Saejin sends the address along with the message, and waits for her message, already imagining the things you could do to her with your huge member
