"Mmm, you've been such a good submissive husband lately," sighed Sandra. "You've been doing everything I asked you to; wearing your butt plug, watching while my lovers fucked me, even cleaning up around the house.
I think that chastity device has worked wonders for you."
"Thanks," I said, "but, baby, I really need to cum. I've had this thing on for over a month now and I'm so horny I'm going nuts."
Sandra laughed "Awww, poor baby. Don't worry. I've got something special planned tonight. Play your cards right and I'll make sure you cum at the end."
"Ok, anything you say" I said feeling a bit desperate.
"Good." Said Sandra. "Get undressed and sit on the chair by the bed.
I did as she asked.
Sandra smiled "Good boy. Have you got your butt plug in?"
"Yes," I replied wiggling around on my seat.
"How does it feel, Mark?" said Sandra.
"It feels tight. I can feel it stretching me." I said. "But it feels good to obey you. I hope it's pleasing you."
"Oh, it is." Sandra replied. "Now I want you to shut your eyes and don't open them till I tell you."
Squeezing my eyes shut I heard her walk out of the room. Then I heard her return with someone else and a lot of giggling. Finally Sandra said "OK, open your eyes."
I opened my eyes to the shock of my life.
"Oh my god! Ingrid?!" I yelled in shock.
"Hi Daddy!" said Ingrid with a little wave.
"What the hell is going on? She can't be here!" I shouted at Sandra while grabbing a cushion to try and cover my nakedness.
"Why because she's our daughter?" Said Sandra angrily, then turned to Ingrid and added "I'm sorry baby. I thought I had your father better trained than this.
Mark, she's adopted. What's the problem?"
"I know technically she's not our daughter," I said, "but we raised her like one and this feels weird."
Sandra shook her head. "Ingrid is eighteen years old now. Whether you like it or not she's a grown woman and she needs to learn about sex.
Since she turned eighteen I've been teaching her about the birds and the bees. She's been practicing using my vibrator... she's ready for a real cock."
"Daddy, I've been practicing so hard." Ingrid pouted. "I want to show you how well I can suck a cock. Don't you want to see that?"
"No!" I said emphatically.
"Come on, baby." Said Sandra "I want her first time to be in a situation which I control so I can make sure she doesn't get hurt.
Baby, I want this, and you want to please me don't you?"
"Yes..." I admitted, "but, you're corrupting our innocent daughter..."
"Daddy! I'm not a little girl anymore!" Ingrid yelled angrily.
"Ingrid, please." Said Sandra. "Mark, honey, you know you can't resist me. You're too much of a slut.
You know how good it feels to obey me. You know you want to please me. Just give in, just go with it, baby."
"I'm not gonna fuck my daughter!" I said.
"What?" said Sandra, shocked. "Of course not. I want Ingrid's first cock to be a big one, so I'm gonna get one of my lovers to do it."
"What?" I shouted "You're gonna get some stranger to fuck my little girl?"
"Baby, you're being silly." Said Sandra. "Look this is the best way. Don't you want to teach her? I promise you this will be fun, and you'll get to cum... you want that don't you... to cum for me?"
"Oh...yes..." I sighed as I felt my resistance slipping away. "But..."
"No, buts." Said Sandra. "You know I always do what's best. This is going to happen, don't fight it. Just relax and be the submissive little slut boy I know you are.
Help your daughter get fucked by a big black cock, and I'll let you cum. Will you do that?"
I felt the ache in my balls, begging for release. "Yes," I whispered.
"Say it baby," said Sandra, her hands stroking my chest, "say you want your daughter to fuck a big cock."
I didn't want to, but if I was ever gonna get out of this chastity device I had no choice. "Yes, I want my daughter to fuck a big cock."
"Mmmn, good boy." Said Sandra. "You see Ingrid, this is the first lesson you need to learn. All men are slaves to their cocks. Get a man horny enough and he'll do anything you say.
Now Mark, I'm going to bring in my lover Curtis. I want you to be on your best behavior and be supportive of our daughter as she fucks her first black cock.
Be a good boy and I'll let you cum, OK?"
"OK," I sighed, as she left the room to get Curtis.
"Thank you, Daddy." Said Ingrid sitting on the bed smiling. "I'm going to make you so proud."
Sandra walked back in holding hands with a large black man.
"Curtis, this is my husband Mark and our daughter Ingrid." Said Sandra by way of introduction.
"What the fuck?!" said Curtis.
"OK," said Sandra with a tinge of annoyance "from this point on I don't want you to say anything or the deal's off. Do you understand?"
Curtis nodded.
"Good. Now, please get undressed. Mark, please stand up."
I did. Sandra knelt in front of me and cupped my cock and balls in her hand. "Now, honey," said Sandra turning to Ingrid, "What do you notice about your father's cock."
"It's so small!" giggled Ingrid.
"Hmmn, that's right." Sandra replied. "You see dear, your father is what's known as a cuck or cuckold. He's not equipped to please a woman sexually."
"So what's he good for?" asked Ingrid.
"Well, lots of things." Sandra explained "A cuck can support you financially, do housework and look after children, eat your pussy when there's no real men around to fuck.
When you grow up you'll have a cuck husband of your own. You'll need to train him to please you."
"Is that what you did to Daddy?" Ingrid asked.
"Mmm, yes." Said Sandra fondling my balls still enclosed in the chastity device. "When I first married your father he was very conventional, sexually I mean.
But by denying him sex until he did what I wanted I soon trained him to obey me. Now he'll do any kinky thing I ask him to."
"Isn't that a bit... mean?" said Ingrid.
"No, baby" said Sandra. "Remember how I told you all men are naturally submissive? That they'd do anything to get sex?
Well, your father goes beyond that. He's not just a submissive male, he's a slut boy.
He'll do anything to please a woman. He loves being dominated. He gets off on being humiliated sexually.
When I dominate your father I'm just helping him become the true slut he was born to be.
