Hm. I dont know about that one. I've never heard of anyone being ticklish in that area. Are you sure she's not just self concious and using that as an excuse because she's uncomfortable with it?? If she really is ticklish then I guess my only advice would be to wait until she's already super turned on and wanting to cum more than ever... When i get to that stage, everything gets so intense, i cant imagine laughing at that point. Why dont you try intercouse until she's close and then try eating her.. maybe she wont be so bashful and "ticklish" at that point because her mind will be thinking about nothing but MAKE ME CUM!
