Comfort Tsunami

You go down to the front of her door, take a deep breath and then knock on the door. "Tsunami?" you say with a fake concerned voice.

You hear a frantic rustling sound; no doubt Tsunami is trying to hide away any trace of her previous action, not that it wouldn't matter since you have the front row seat to her performance few minutes earlier. "Wait a moment."

"Take your time," you say as you wait leisurely while telling your erect little Naruto to calm down but to no avail.

After few more minutes, the door finally opens and Tsunami peers from behind it. "What is it?"

"I'm just checking around, since I hear some noise..." upon seeing her expression beginning to change, you quickly change your words, "from outside, I think."

"From outside," Tsunami says in a poor attempt to affirm your words. "I've been sleeping but I do hear something from outside just now. What kind of sound is it?"

"Some branches being stepped on. That's why, I come here to check on you. Oh! right!" Continuing your charade, your create four shadow clones and instruct them to check the perimeter of the house. All four roll their eyes at your poor acting but they leave to do their duty nevertheless. "As you know, with current situation, there's probably some stupid people aiming for your family,"

Even though Tsunami was trying to pretend that something else was responsible for the noise she made pleasuring herself, your comment cause her expression to change into a concerned one. This is the opening that you can take advantage off to invite yourself into her bed.
