About 3 weeks ago I posted how my Master punished me with a cock in my ass. Since then we haven't really done any butt stuff except him eating my ass. Most of our focus recently has been having two or three guys feel me up at the same time or a second cock for my mouth as Master fucks me. So it was decided the other day I would dress up in a red dress that was rather short. We went out bar hoping looking for prospects, and I ultimately didn't see any guys I was interested in. We got back to my place and started having our fun. There was lots of lube and I found myself with Master's thumb in my ass as he plowed me from behind. Then we got toys involved. Most of my toys are non penetrating vibes. I do have one dildo with a second small knob I believe intended for clitoral stimulation. Well I found the proper dildo portion in my pussy but the toy reversed so that little knob was in my ass! Eventually Master put me to the test and sunk that swollen cock head into my backdoor. The initial peneration was painful, but my body eventually relaxed and accepted him. He didn't pound my ass. Instead he gave it to me deep and only pulled back a bit before pushing in again. It ended up being a really fun satisfying experience. So much so the very next day I invited Master to use my ass again. This time we didn't have alcohol to take the edge off. Delicious foreplay, lots of lube, taking it slow in the beginning. My body, well my ass, relaxed and accepted his cock a lot faster this time. He gaged my response and ramped up the speed and intensity of his thrusts to my tolerance. Eventually he was straight up plowing my ass until he busted his nut in me. I think I'm now officially a butt slut!
