Cassie is alone wearing a black bra. Her armpits stink because she's been working out recently. She picks at it, licks her own armpit, and then sticks her slobbery finger in it. He enjoys it very much, but she has to keep smelling herself. She comes. After she had an big orgasm, she feels the saliva mixed with the sweat in her armpit and it smells extremely bad. She smells herself, but she has to fist. She doesn't understand how it can smell so bad...
