It's kind of sluggish and inarticulate! There are two men in the room and I didn't see any sex per se. The older man tries to pull the lady as much as he can, and the young one just jerks himself! And you could have made a great video with an interesting set of different double penetrations. That would have been really interesting!
The sister decided not to flick her face and join her brother and wife while they offered. And the process went well for them. The brother fucked the sister well, and his wife fully supported him in this.
