After Carol had showered we all had to get our tests done by Mary the big bodyguards wife, a trained nurse as well as being my brother's tutor. She was a big black momma around twenty stone. She took a blood sample from my finger then told me to drop my trousers and underpants.
I was rather shy but did so and she held my prick and took a scrapping off of the cockhead. Now she said, as I'll be expected to make her equally black daughter my new sister in law pregnant she wanted a sample off my sperm to check for abnormalities.
I was ashamed as my prick was at its smallest in front of this woman. Mary came to see how I was getting on and said, "Let momma help you boy." She started to manipulate my cock but it didn't help so she put her lips around it and sucked and licked at the same time.
Naturally this helped but I was still only semi hard I felt so humiliated, what was wrong with me lately? Before my accident I'd only needed to think about a sexy woman to get a hard on. Now even with this oral stimulation I couldn't manage it.
She said softly, "Youse gonna need more help baby!" Then the big older black lady stripped. Her huge pendulous tits hung down to her waist with nipples at least an inch long. This fascinated me I had to suckle them, they elongated and amazingly I felt milk squirt out.
I used both hands to lift one massive black breast at a time and sucked from it. She said, "Old Mary gets someone to milk them every day or I do it myself you like it boy?"
"Yes Mary" I said, I love your big titties!" My cock was hardening but still not fully erect, what was wrong with me?
She felt my cock and rolled a condom onto it but this had a negative effect and my penis deflated so the rubber started to slip off. "Man youse got a real problem there," she said, "I'll have to take drastic action."
She put a videotape in the player; it was of my wife sucking her husband's big black cock. Immediately I became hard and she rolled another condom on to it. Now where would you like to put it to make sure you cum good I wonder? How about fucking old Mary, you can fuck my tits, mouth arse hole or cunt white boy, which will it be?
I was gob smacked never having fucked a black woman or someone as fat as Mary. I stuttered, "I----don't know"
"Well then I'll decide for you babe" She said, "I need your little white prick in my fat black cunt!
I looked down but her belly covered her genitals completely. I couldn't imagine how I'd achieve it but I was iron hard now and my cock wanted to penetrate this massive black woman.
Mary laughed seeing my confusion and said, "You do me this way babe." With that she stood with one foot on the floor and lifted one onto a chair then bent over. Her pussy was huge her outer jet-black labia hung down at least five inches. I felt then parted them to find her treasure within.
Her inner labia were lighter and massively swollen pumped up by blood from her desire. Inside them her massive pink vagina swum with oily lubricant. I was fascinated and pushed my entire fist inside and fucked her with it.
With the video of my wife sucking the big black mans cock and this new stimulation my cock was ready by now. Mary said, "That's good man but don't forget what you're here for to give a sperm sample, stick it in!"
Considering the size of her hole I thought I'd not feel a thing but despite the condom, it felt like I was fucking a tube of warm treacle. My whole body felt absolutely fantastic, her massive buttocks quivered as I rammed my cock into her. Still see my wife's image on the video, by now she was sucking off the eighty year old black man.
Though I'd been rutting into Mary's massive gash I wasn't getting near to cumming being restricted by the condom. I told Mary and she said, "Well young man the idea is to collect your sperm, still I suppose I can recover it if you don't cum in my hole. Hearing this I ripped the condom from my cock and mounted her bare back.
God this huge black woman was sexy. She said, "Ken, I know I look old because of my weight but I'm only forty two and still have periods. My husband had the snip years ago because he could pass on a genetic disorder. If you come in me you could impregnate me because I am very fertile at the moment, so you'll have to pullout and shoot into this glass!
"Yes I agree," I said and pushed it in her vagina again as hard as I could. She squealed and got right into it immediately. Her pussy was spasming and squirting her cum as she had her organism. She never stopped twitching coming again and again.
She started shouting breathlessly, "Fuck me Ken, put your sperm up me and impregnate me. Give me your baby; knock me up with your white baby! Old fat Mary wants your spunk in her big cunt!
There was no way I could hold back or pull out in time and thrust forward to get as near to her uterus as possible. Then shot my birthing liquid strongly several times into her cavernous unprotected cunt. We lay together in the afterglow till my cock shrank down and I dismounted from her huge body.
Mary kissed me on my lips and said, "If I can't get a sample from my hole we'll just have to get you to give me some more spunk won't we babe!" I replied breathlessly, "You bet Mary anytime!"
I felt wonderful but was still worried what would happen when I had to perform in front of other men with longer cocks.
What had we got ourselves into; I couldn't believe how our married life had changed. Before my accident we were happy and in love now what would happen?
Could I really go through with it, letting my wife prostitute herself to an octogenarian black man?
What if she didn't get pregnant the first time and he had to do her over and over again? His old scrawny body doing whatever he wanted with my only true love!
I knew she didn't care, she loved old men with big cocks it was her fetish as was selling her body.
The fateful day arrived and Mary told me I was clear of any disease and my sperm count was high. She told me some other news I'd made her pregnant; she was over the moon as was her family including her husband. As he was twice my size I was glad of that. "Now," Mary said you've just got to impregnate my daughter and your duties are done stud.
I felt good about fathering a child with cuckold Mary, but this time my cuckolding would be in public. Carol was an exhibitionist and loved people watching her have sex. But I was a voyeur I liked to watch my wife being fucked, not people watching me fucking.
Carol and I both stripped naked and were taken into the fateful bedroom with the mirrors videos and observation rooms all around it. I'd rather have been watching than taking part but Carol my wife was insistent I watched her being impregnated. She also wanted to watch me impregnating my black sister in law.
The old man was brought in his wheel chair and lifted onto the bed with the velvet sheets. He was even skinnier the cancer was really taking hold now. His giant black bodyguard lifted the frail old man onto the bed naked.
The old black guy was no more than skin and bone toothless and decrepit that was with the exception of his long black cock that seemed immune to the ravages of time. The long shaft although flaccid nonetheless extended almost to his knees. One bony hand reached out and felt my wife's pussy she opened her legs and he pushed a skinny digit into her.
