I had a psych prof who picked up a stapler with a big knob on it and he said that even tho he had never put this stapler in his mouth, he could tell exactly what it would feel like and taste in his mouth because of the experiences he has had putting things in his mouth... yes it got a laugh. The point being, cock in your mouth is going to feel just like you think it will. The taste is going to vary from dick to dick, and every penis is different, but I bet you can imagine it... and if you are imagining it, you probably are going to manifest it in your life. I remember the first dick in my mouth. It felt exactly like I thought it would, but it was such an exhilerating experience that I didn't realize how perfectly natural it felt.
