Trinity needs to learn CPR, but her instructor doesn't have a dummy. That means it's his mouth she has to blow into and his chest she has to compress. Of course the mouth-to-mouth leads to mouth-to-cock. Trinity works his head with her little mouth, trying to squeeze in as much as she can. Then the instructor does the same thing to her--squeezing as much of his cock into her pussyhole as he can--but he gets much more than the tip in. "You're a good teacher," Trinity says as he slides his cock in while she's on top. Now Trinity knows how to save a life, and how to catch a big load of cum all in her mouth!
