My sweet sissy Ami was all ready and waiting to please me. I had given her a beautiful silver cock cage to put her little clitty in. It was one of the newer ones that had small spikes that would rub against the clitty if it started to get big. I couldn’t wait to see how it worked. I put her in thigh highs with a garter and heels and nothing else. I wanted to be able to see the cock cage at work. Ami’s weakness is cum. She can’t get enough of it. I think she would live on a cum diet if she could. But since I am her mistress I decide when sissy Ami gets some cum or not. I promised her that if she could go all day without her clitty getting hard that I would let her use a dildo on her man pussy while blowing the man of her choosing. Ami thought she had this until I yelled for her to come into my room. There on the bed lay a marvelous man with a marvelously hard dick. I had Ami sit on the bed beside him as I took that big fat hard dick and stuck it between my gigantic tits and titty fucked him. I could see Ami watching in lust every time that big head appeared between my boobs. Before long, my friend was squirting his load all over my breasts and face. Ami watched as I licked his creamy cum off his dick. I went to check on Ami’s clitty and it was still soft. I was so proud of her that I let her lick the cum off my tits. That was too much for Ami’s little clitty as she flinched in pain as the cock cage rubbed on her little hard clitty. But Ami didn’t care, she just kept lapping up that warm thick sperm from my breasts. My little sissy is a real cum slut.
