Madness with Finger Rings

THE MADNESS.......!!!
WHAT MAKES ME INSANE....is my wife giving me tight "rings".....let me explain....she copiously oils my cock (coconut oil is best)....and as it is so well lubricated she will toy with it till i am rock hard. Slowly she will get the foreskin down...to expose my head....and now she takes complete charge of it...by making a ring of her fingers and thumb...and makes me "penetrate"...that ring! She has total control over how large is the ring or how small and tight it is...there are times where she would make the ring really slowly....and just hold it over my tip. This is so uncontrollable that I begin to thrust in to penetrate. She is so clever that if I manage to "penetrate" it with force...she tightens the ring so hard that the cock head is stuck half way....The pain-pleasure complex is truly maddening.....I feel my heart racing and myself arching hard to fuck the ring....and she is sitting between my legs laughing hungrily watching my desperation to penetrate for peace.....This she repeats so often till I shoot so hard.....
Often she will be kind enough to let me penetrate the tightly made ring of her finger, but then squeeze it really tight in the groove below the glans and then just attempt to push is down slowly but firmly down the shaft pulling down the whole of my foreskin....this is maddening...!
Ladies and men....this is a must try....!!
