double penetration with her dog and man

I truly come to love having sex with a girl immediately after dogs have been with her, as I watch.
But I've always wanted a woman that allow herself to be DPed by a dog and myself, in the same hole preferably.
I wanna feel a hard dog cock, with the knot inside her, pressed against my dick as I fuck her and rub across the doggy's dick at the same time.
