>Or do they basically return to "normal" afterwards..?
Lmao, no.
Despite what some Copers would have you believe, overall use does in fact stretch it out and it does not fully return to original. The slight exception would be for women who are still quite young. Their pussy elasticity and muscle tone is obviously going to be quite better than that of 21+ yo women.
For example, I've had sex with an 19yo who had given birth at 16, had a total of two past partners and her pussy seemed perfectly normal and adequately tight. I've also had sex with a 27yo who gave birth at 25 and had what I can assume was at least 10+ partners, her pussy was very loose, comparatively. Both were about the same in "wetness" and slim/small physique.
So, yes, if you have sex with a woman above the age of 20-21, and she's been regularly stuffed with large objects, her pussy is going to have adapted to it. It will adapt to the average size of whatever necessary. So, if it's been 10 small cocks, then that's what it's adapted to. 10 massive cocks, then that's what it's adapted to.
It's the same as lifting weights, in a sense.
