JR7, I too have experienced what you describe describe very well, too. On three or four occasions I have gone into a pussy that was so creamy, and that sucked me in so much and so quickly, that it has been difficult or even impossible not to come straight away. Interestingly, all were big women not overweight, but curvy and buxom and well covered.
Interestingly, too, each time when I did come way to soon, the girl expressed no surprise or disappointment, as if this was a normal thing, and was more than happy (indeed, insistent) to go for a second round. So my guess is I was not the only one, and perhaps "super pussy" is the right term.
The problem of coming too quickly was less when we met again (as I did with two of these women): I guess I was ready for what was in store, although even then I would come more quickly than normal, on one occasion I remember not because I couldn't stop myself but simply because it felt so good I didn't want to.
I can't really explain the sensation that these pussies gave me, but I am glad to have experienced it. I'm glad other people have too, since it makes me think it wasn't just my mood at the time or anything like that.
