Suddenly, a knock at the door disturbed us. I froze at Markus and squeezed the collar of his shirt, while he took his lips out of my neck and looked at the door. The knock repeated, so Markus asked who it was.
"Rick." Said the voice behind the door, and we saw that the handle moved as if he put his hand at it, meaning to enter.
"Should I?" I asked, but Markus squeezed my waist with his both hands, not letting me stand up from him. I blushed, imagining Rick coming inside and catching us in this pose.
"Later," Markus said loudly to Rick, then squeezed his hands at my waist and started moving my lower body, showing me the right rhythm. The goosebumps run up and down my body, I squeezed his shirt and began to move due to his rhythm. I started moaning and pressed my lips to his neck in order to muffle the moan. It wasn't clear yet if Rick left us or still waiting there.
