The pill works by tricking the body into thinking it is already pregnant so it does not release another egg. For appartently many women, that also leads to a decreased sex drive because the natural reason for sex is gone. She has stated several times she did not realize how much the pill had restricted her sex drive until she came off of it. She almost immedialtely became a lot more horny. Because of the nature of the sponge, yes she has to think about it everytime she uses it. It also makes it very hot for me as well. As i fuck her full of his sperm and enjoying how good it makes her pussy feel, i sometimes think, what if she forgot or what if he took it out. Those thoughts make me cum almost immediately.
