Surprise. this is not a rubber ass but you sure like it better.

New partner at the massage clinic. since it's my turn to teach him, i joke around with a rubber ass and tell him it's for him to practice with massages. she left him for just a moment and when i come back i catch him with his cock inside her rubber ass. i'm going to give him a good lesson and when he comes back from the bathroom it will be my warm and tight ass that he fucked.
