There's no way to know unless you can understand Japanese, as there's nothing in the pictures to suggest anything. Even though Tamaki is the NTR queen and the setting of the game would make it NTR, this parody itself is a standalone.
Just wanted to add on why this is not NTR. in this story Takaki started dating Konomi, Tamaki who thought she can cope with it started to have a relationship with a teacher instead. Then POV shifted to Takaki, who received a Disk from Yuuji. Takaki for most of the part started commenting while not realizing it was tamaki (Lol...so dense), he also comments about feeling jealous and comparing Konomi to the girl in the video. After the video stopped censoring her name and face, he realized it was Tamaki all along. POV shifted to Tamaki again, revealing her virginity is going to be taken in the video. It finally ends on Takaki questioning the whole situation.
