Bigger cock for wife

So we’re a couple 30 & 29 in Auckland with a fantasy of surprise sharing with a bigger cock. Everything would be anonymous, no names, face, talking, touching, sucking etc but everything would be discussed prior. Around our age or younger, chill and in decent shape would be ideal. Has to be bigger than 7-8inch with proof. Must be clean, non smoker and condom has to be worn. For her first time she ideally wants it slowly worked in, fucked for a bit and then you leave so possibly only 5-10 minutes, it might happen again it might not who knows! Please only dm if you fit the description and can send a pic less
