An open slit would drive anyone crazy. When this bud is so attracted to inhale its aroma and enjoy the taste, when the woman herself does not mind to be fucked - it is impossible to stop. And the desire in her eyes pushes to plunge into her as deep as possible. How can you resist the temptation to cum inside her? What a bitch - she smears the juice with her fingers and tastes it. And she likes it.
I've had that experience with two guys. That's great.
