Having fucked several women in their 40s when I was a teen, I’d say if you last more than a minute inside the asshole of an older woman, you’re better than most guys. The whole mental picture of you in an older woman’s ass bareback, the warmth, the tightness, the smell of her ass, how could anyone hold back? I think I lasted no more than a minute with them. Nice thing about being in your teens is that you can get hard again within minutes of cumming.
