No not ok but absolutely gorgeous. I would love to pull your foreskin back when your cock is already buried in my mouth, then run my tongue over your frenulum and wait 'till you shoot your creamy cum down my throat! Mmmmm
It doesn't look tight, the movement of the foreskin is pretty good. I think I would call it tight if your had to forcibly push the skin forward over the head or even squeeze the head to make it smaller and get the foreskin over but it glides back and forth really well.
