That's because lvl5 Nami scenes are not ready for this update. As for Tatsumaki - did you see her on the rooftop? After you complete Hinata quest, you will be able to find Tatsumaki on the 1st floor at school.
ohh i see, thanks! Also, is there a nami sex scene in the beach?
Yes, it is, you need to get 50+ Attractiveness to have sex with her
