Luis,
The scene begins with a man, who fucks the actress and ejaculates in her mouth.
A second actor fucks the actress and ejaculates in her mouth.
A third actor fucks the actress and ejaculates in her mouth.
A fourth actor fucks the actress and ejaculates in her mouth.
The four actors return to the scene together, they fuck the actress, and at the end of the scene, they ejaculate in the actress's mouth.
What do you think of this idea ?
