At 13 I did not know what an orgasm was but I am very sure I had one that day because I had this tingling sensation all over my body and I had to push Rusty away and close my legs tight because his licking was hurting my pussy.
If this bothers you, consider asking your doctor about an alternative birth control that has less estrogen.
I have let my dog lick my pussy and I must say I really like it.
