Doggie. Especially if I'm up on my hands rather than elbows. He's at a the oerfect angle that when me cums it hits a sensitive area if nerves.
Doggie position...Actually our lover fucks my ass while I'm on top of my wife in the 69 position. I love being fucked and sucked at the same time while eating pussy.
My wife and Tom's wife have said they wished they had a cock when pegging my ass. I'm slowly loosing my sexy ass so I want to flaunt it to the three of them for as long as it is still perky and plump. I'm the only guy Tom has ever fucked in the ass and says it's as equally wonderful to fuck as his wife ass and she and I both enjoy his big cock deep inside our asses. He's a heavy cummer too so his finish is an amazing feeling.
