It is always just straight missionary sex, nothing else. I never found Lana&Robert very interesting at all, but rather boring.
And just like with Leora and Zoya, the action is often unnaturally pointed right towards the camera.
If you want a couple with a more interesting, yet natural sex life, with actual dynamics during the sex, and with natural variation, try watching Eva&Sam, Adeline&Marcus, Nelly&Bogdan, Linda&Tibor, Martina&Alberto, maybe Stesha&Marco. They are very good.
