I tried heavens fall nine and its not very stimulating. Except for the beginning but after that it gets kinda bland and makes me have to work harder. I want some help to find something very stimulating under $100. I will take any recommendations at this point. The only onahole that actually was very stimulating for me was the"Toysheart longitudinal fold spiral HARD" but mine got worn out after a year and I cant find it anymore. Please help a brother.
