"Jeeez, Dad," complained Jake. Innocence couldn't see him but she assumed he was blushing.
"No, really, sweetie," said Melanie. "She's yours and we expected you to use her sexually. We bought her for you."
Jake gasped. "You bought her?"
"Yes, Jake," replied Dave. "We bought her for you. Well, we bought her for a day. So I guess we rented her."
"What? Is she a hooker or something?" asked Jake incredulously.
"No, dear," assured Melanie. "She's someone's slavegirl. She was auctioned off tonight at a party we attended. And your father and I bought her for you."
"Yes. Happy birthday, son," added Dave. "Oh, and by the way, she has a very talented mouth. Be sure to use that too."
"Jeeez, Dad," Jake said again. "That's more than I needed to know."
Innocence heard footsteps and quickly saw Melanie leading Jake by the hand back into his room. She led him closer until they were standing beside the bed where Innocence was bound. Innocence could see that the son was blushing furiously.
"Isn't she beautiful?" asked Melanie.
"Yes," said Jake in a small voice. "I guess so." His eyes would start to roam over Cency's body and then he would avert them, being too embarrassed to overtly stare at the naked beauty.
"There's no guessing about this one," said Melanie. "She's gorgeous. She's perfect in every way. And she's all yours until tomorrow night. Do you know how to use her?"
"Of course I do," he replied indignantly. But his blush deepened. "Sort of… No, not really." His eyes started to tear up as he admitted his lack of experience.
Innocence watched as Melanie hugged her son. "It's okay, sweetie. We didn't think you had done it. That's why we bought Innocence."
"Innocence? That's her name?"
"Yes, that's her real name. And she's just so perfect. Let me give you a guided tour. Or would you be more comfortable if your father showed you around the girl?"
"No, Mom," he said. "I think I'd rather have you do it."
For the next five minutes, Melanie showed her son around a naked female body and described how many of the parts could be used for pleasure. She stroked her finger in and out of Cency's mouth, illustrating how a blowjob worked. She untied the ribbons and toyed with the sensitive nipples, sending unwanted thrills through the captive as the little buds stiffened.
"Feel how firm these are," she said as she squeezed the left breast. Tentatively, Jake reached out and squeezed the right breast, causing Innocence to blush anew.
"Yeah, I guess they're firm."
"Oh, trust me," she said. "These are very firm. These are prime quality. Let me give you a comparison."
Cency's eyes grew wide in surprise as she saw Melanie pull her top off and then reach behind her back to unhook her bra. Jake gasped. "Mom!!!"
"Oh, don't be such a prude," she said. "I'm just giving you a lesson." She reached out and grasped Jake's wrist, bringing his hand to one of her breasts. Innocence watched as the boy's fingers squeezed into the fleshy orb. Innocence saw that Melanie's breasts were also very full and firm with hardly a hint of sagging despite her age, which Cency guessed to be about forty.
"It feels pretty firm too, Mom," Jake said.
Melanie leaned forward and kissed Jake on the cheek. "You're so sweet. But this girl's breasts are much firmer." Then she resumed the guided tour without bothering to put her clothes back on. Jake had a hard time deciding which breasts to watch as the lesson continued.
Innocence groaned as Melanie snuck a finger into her sex and then pulled it out to show Jake how shiny it was. This was like a pornographic version of sex education.
"See how wet she is?" asked Melanie. "That's a good sign. It means that she's aroused."
"Why would she be aroused?"
"Because she likes it. Most slavegirls are always aroused." She ran her finger around Cency's little asshole which was not easily accessible because of the way she was tied. And then she finished by toying with the girl's clit which she had painted with her lipstick earlier.
"Now it's your turn to try out the girl," Melanie said, once she had finished the class. "Take off your clothes. We'll start with straight fucking."
"Mom!!!" he blurted. "I can't take off my clothes with you here."
"I don't see why not," said Melanie. "I took off my clothes with you here." Then she unzipped her skirt and slid it and her panties off, leaving her only wearing her heels.
"There," she said with her hands on her hips. "Now we'll all be naked. Now off with those clothes."
"But Mom!"
"Now, buster!" she commanded.
Once again, he was blushing furiously but he obeyed his mother. Quickly he was naked and he used his hand to shield his cock, which was quite erect at the moment, from the view of the two women. Innocence noted that it was quite a bit larger than his father's.
"Oooo!" squealed Melanie. "You have a nice one." She reached out and pried his hand away before gripping the huge shaft with one of her own hands.
"Mom!"
"Oh stop being such a ninny. Now get up on the bed and kneel between her legs."
Again, he complied and then Melanie positioned him correctly, continuing to hold onto his cock and guide it to the girl's awaiting sex. Innocence looked up and saw the panicky look on Jake's face. She could only guess at how embarrassed he was to have a witness to his first time with a girl; let alone having his mother handle him so intimately.
Innocence felt the cock rubbing at her petals and then stretching them open as the shaft was pushed into her. It had a very impressive girth and she could feel every inch of movement as it started to fill her.
"That's it, Jake," Melanie said in encouragement. "Now take it all the way in."
"Good," Melanie continued. "Now start moving it slowly out but not quite all the way." Innocence felt the shaft start to withdraw as Jake followed his mother's instructions.
"Now back in," said the mother as she continued to coach her son. "How does she feel?"
"Good," he said. "She's warm and tight. But I don't get it. What's the big deal with this?"
"Oh, you'll get it soon enough," replied Melanie. "Just keep moving in and out and let me know when you start to get it." She knelt beside the bed and rested her chin on one of her arms as she watched the thick pole of her son plunge into the girl. After a few more strokes, he spoke again.
"Oh, I think I'm starting to get it. It's getting tingly."
Melanie smiled and reached out with her other arm. She placed a fingertip on Jake's slick and shiny shaft, feeling it move past her finger on its way into and out of Cency's swampy sex. Then she moved her hand and captured his balls, cradling them in her palm. They were warm and larger than she expected. She knew they would be full of his sperm and those little swimmers would soon be deposited in the girl's womb in search of an egg to mate with.
"Slow down there, slugger," she told her son as she saw his pace speeding up. "You don't want to shoot too soon."
Jake groaned. It was hard enough that he had his cock buried in a real live girl for the first time. But his mother's touches and the fact that she was totally naked with him were not helping.
"Stop completely for a bit," Melanie said. "Just rest yourself inside of her. I want to show you something."
Jake groaned again. This was becoming torment. But he did stop and waited for whatever demonstration his mother had in mind.
She moved her hand and placed a finger on Cency's clit, causing the humiliated and impaled slave girl to tense. "Now look down here and watch what I do. But whatever you do, don't move in her. You don't want to end this too soon."
