Face-Sitting (Pixiv Fanbox)

Here we see two trainees having a session together, though only one of them may succeed. The trainee on top is not allowed to cum, but must remain sitting on the other trainee’s face. She may do anything she wants to the other trainee, who happens to be incredibly ticklish. The trainee below must make the trainee sitting on her face cum within 30 minutes. If she fails, she’ll be edged and then forced to wear a chastity belt until she manages to redeem herself in other sessions. Of course, it’s not an easy task to focus on stimulating someone else while your armpits are being tickled mercilessly. I recommend putting in some effort though because the time is almost up and it doesn’t look like the one on top is close to reaching an orgasm~
