>>34497688When she is really turned on, her vagina will be well lubricated, and she will almost be begging you to make her cum. The best way to do this is to use one or two fingers. If you are a male, do NOT try inserting your dick into her unless she is one of the Giant Breeds, (or you have an exceptionally small dick). If you hurt her, she may become frightened of you, and will not enjoy the sex.
Move around behind her and insert one finger gently into her, slowly. If she isn't wet enough, use saliva or KY jelly. Don't use mineral oils or anything that isn't used for human sex. As your knuckle brushes past her clitoris, it is likely she will sharply hump her hips downward. This is normal. Slowly withdraw your finger, and repeat. She should start humping up and down on your finger quite strongly. Keep in time to her movements, pushing up as she humps down. Use your other hand to caress her nipples and stomach. She will cum fairly quickly and easily. You can tell when she is, as you will feel her vaginal muscles squeezing on your finger and she will start convulsively licking her lips. Try to sustain her pleasure for as long as you can; play with her clitoris. Generally treat her as you would a lover.
If your dog is one of the Giant breeds, and you are male, by all means screw her. Highly recommended in fact. She will hump your dick as readily as she will hump your finger. Crouch behind her (or have her stand on a slightly raised platform) and guide your dick into her with one hand.
