Serving a black bbw - part 2

I arrived promptly at 7 that night, I was very horny but my expectations were of oral servitude... I loved it but ached for more, oh so much more. She greeted me and we entered her dining room, there were several places set at the table, 8 to be exact. She told me she was hosting a dinner party, and I was to be her boyfriend for the evening. The guest arrived, all couples about our age. We chatted, I was introduced and other than being VERY attentive to her needs noone would ever guess our dynamic. It was a pleasant few hours, and I was proud that she presented me as her boyfriend to the world.

Most of the guests had left, save one couple... he was a tall black man, and stoutly built, and she was a magnificent white BBW.. with breasts that were hard to ignore. They were sitting on the couch, and we were clearing away the last of the dishes, I noticed her hand strayed to his lap... a bulge very apparent. My mistress entered the living room, and sat down next to him, her hand grasping that bulge. She was looking at my face as she unzipped his pants, a rapidly hardening cock appeared... a couple of inches larger than my 6" cock, and just a little thicker. "come here" she commanded, I found myself kneeling and watching as she started to suck that cock, stopping every now and again to ask me if I liked it, if I wanted my cock sucked. He was enjoying the attention of both women, his wife kissing him, caressing his balls as my mistress sucked his cock. Time for the bedroom she announced, and her friend giggled and agreed. Once in the bedroom, I was told to strip first... they all watched as I disrobed. Her friend inspected my body, reached out to stroke my hard cock... "he'll do" she smiled and started disrobing herself. While my mistress and her husband started to fuck, I was once again presented with a wet pussy and ass that I was expected to service. I worked quickly now, I had gotten better at oral with all the practice and I made her orgasm in short order... dutifully, I continued to lick as she grasped my hair and fucked my face. I got lost in the moment, and did not see who was behind me...I felt hands on my ass, as a lubed finger slipped into my ass... it was my mistress, she was grinning ear to ear as she played with my ass, the husband was standing beside her, stroking his cock... still wet from the fucking of my mistress. She had strapped on a large black cock, and was intent on using it. She moved behind me, and positioned the massive cockhead on my tight asshole. The strapon was 9" long I was told later, but it looked MUCH bigger in the moment. I had only ever had a finger up my ass before, so as she pressed forward and the head slipped in ... it hurt...a lot. I gasped into the pussy I was eating, losing focus for a moment. The woman I was eating laughed, and pulled my face into her pussy as my mistress relentlessly pushed forward, me gasping in pain with every inch. She managed to get several inches into me, and just stopped...letting me adjust, and talling me "what a good bitch" I was.. she started slow fucking movements, the pain eased a little and I was able to continue oral service. She picked up the pace, fucking me with gusto...she appeared to be approaching her own orgasm, which I did not understand at all.. my ass was taking all 9 inches now, my cock was leaking like a sieve and I started to enjoy the sensations. She finally gasped and pushed it hard into me... grinding her hips in a circular motion as she came. I was released from my oral servitude and turned to see her removing the strapon, turns out it was a feeldoe, and part of it was inside her as she fucked me. She explained later that it worked better with the straps, but could be used without. I would become very familiar with that in the days and weeks to come. I laid on the floor, reaching for my ass, tracing a finger around it gently, it was open and sore but I felt an odd satisfaction from losing my "ass cherry" as she put it. After our guests left she told me that I had done well, and would be rewarded. She stroked my cock, making it immediately hard, she told me that an orgasm for me was a reward, not a right. She climbed on top of me, sinking that hot pussy onto my cock. It was AMAZING, she rode me skillfully and with purpose.. I was soon gasping and begging for permission to cum, but before she could answer I filled her pussy with cum. She got off of me, "you will be punished for that later", and all I could think was " odd, that I am looking forward to being punished"
