My wife won't try or do oral sex. I sort of have a fetish for it. I go on the internet and masturbate watching oral porn. My wife's sister I learned is a secret slut. She doesn't have a man in her life due to the fact she's nearly a SSBBW and not much of a breast on her. She spends a lot of time in our house. Then one day my wife was called and asked to work that day. My sister-in-law was asked by my wife to keep me company for a while while she worked.
I was bored that day and got on the computer watching porn. I didn't know my sister-in-law was spying on me. I never close the door when my wife isn't home. I was tugging on my dick and I heard my sister-in-law say, "Being naughty? " I quickly shut down the computer and zipped up my pants. "If your sister was interested in oral sex, I wouldn't be doing this. " I said to her asking her not to say anything to her sister. She then tells me she won't say a word if we play for a little while as she massaged my privates and tells me my dick looked good enough to suck and unzips me and turns on the computer to find a BBW porn site and exposing herself to me. I rubbed and felt her small breasts and she pulled out my dick and began taking it in her mouth. Oh she was getting me really turned on. She put it fully in her mouth up to my balls which she fondled. I enjoyed it so much that I held her head there.
" I can take and taste cum with no problem, so don't hold back, babe! " We got on the bed and started doing a 69. I rubbed my dick across her nips and she opened her mouth with her tongue moving about waiting for me to explode. I didn't realize that she was playing with her clit as I shoved my dick in her mouth like it was a cunt and gave her my load. She smiled and open her mouth for me to see my load in her.
When my wife came home, I told her that her sister could come over often. Then we got in bed and my wife jerked me to satisfy my sexual urges making me cum all over her breasts and wiping it off with a towel. Deep down in my mind I rather of shot it in her sister's mouth now that know that she's a fat cum slut.
