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.
Sometimes you don't want to race horses so much. When you first let your partner relax, sensual sex, then the next times she will definitely not refuse, or even come herself.
