My wife Shannon has not been with another lover for awhile now and she has been taking her frustration out on me. One evening awhile back we were out partying and having a good time when my wife introduced me to one of her girlfriends,Abby, turns out she a domintrix. She starts telling us stories of what she makes guys do, clean her apartment, do her laundry etc.. She goes on to tell how she makes guys jerks of in front of her and lick their cum off her shoes, and how she fucks her boyfriend in ass on a regular basis, he's sitting at the table with us. She turns to him and tells him to tell us how she fucks his ass and much he likes it. He turns red with embarrassment, but he goes on to tell how he lays on his back and holds his legs up so she has access to his ass and how he has to begg her "fuck his ass hard like a lil ass slut." I'm sitting there thinking I better not get to drunk and pass out or I may wake up with a sore ass. Then she starts to tell my wife that she should be fucking me in the ass so I would know my place. I look at her and say "what" she says "yeah you look like you need your ass fucked". At this point I'm getting a lil scared and thinking maybe it's time to go home. About that time I look over at my wife Shannon and she is clearly turned on with a mischievous look on her face. A couple days go by and I've pretty much forgot about the other evening, when Shannon tells me she has a surprise for me, I'm excited and ask what is it? She tells me to get naked and get in bed. At this point I'm horny as hell because Shannon rarely allows me to have sex with her, usually I am told to jerk off while she tells me about her and her current lover. I get in bed all excited thinking I'm going to get laid, when she comes out of the bathroom wearing a leather strap on with a big black cock. I yell what's that, and she says you know what this is. Then tells me she is going to fuck my ass and I better not back talk her. I stammer out a "yes ma'am " she says "that's more like it, you will address me as ma'am for now on". Yes ma'am . She lubes up her cock and my ass and starts working it in all the while I'm begging her to be gentle. She tells me to shut the fuck up a and take that cock bitch. "Yes ma'am". By the time she is balls deep I have tears running down my face and she tells me begg her to fuck me hard. "Yes ma'am please fuck my ass hard I cry out". She starts laughing at me telling what a lil bitch I am with a black cock in my ass. She starts stroking my cock and I can't control myself and cumm all over her hand which she makes me lick clean. She tells me I'm a good lil bitch boy. A couple days later we are out drinking when her friend the domintrix shows up, Shannon turns to me and tells me to tell Abby what we did the other night. I turn beet red with embarrassment , she gives me a stern look and says don't make me repeat myself. I turn to Abby and have to explain in detail how Shannon fucked my ass. She says I know Shannon already told me , I just wanted to hear it from you. Lol That was the first time Shannon took the strapon to my ass but certainly not the last, any time I get a lil to full of myself she has me get her strapon and put it on her so she can fuck me.
