In the aftermath of sucking their first shared cock, sandy and steven knelt staring at each other wearing rather startled faces, whilst the more senior adults in the room reveled in the teen's submission, and the monumental moment they had all witnessed. Any doubts about the sexual curiosity felt by the 18 year old twins had dissipated, even if the awkwardness of the situation that the family were in remained.
The older twin whispered to his sister. "God, sandy - what was that?"
The slightly younger twin blushed to match her red hair as the taste of Master's cum, and her brother's mouth clung to her lips and tongue as a reminder of the act she had just committed. "i-i-i'm so sorry, steven." The young woman's chin trembled slightly as she grappled with the fact that she had not only kissed her brother, but passionately Frenched his cock-tasting mouth. In the heat of the moment, seeing Master's cock erupt before her face, knowing she and her brother had made Master feel so much pleasure that he had cum all over them had made her feel incredibly sexy.
When Master had ordered her to lick up his cum from her brother's mouth, she hadn't even hesitated, she had simply acted. Had she read this all wrong? Had she just damaged her relationship with the person she felt closest to in the whole world?
From the sideline, slave maryanne watched her son put an arm around his sister and hug her. The concern on sandy's face was obvious, and she wanted nothing more in that moment than to rush over and join him in comforting her, but she also saw the bond between brother and sister as they hugged on their knees on the floor, still glistening from Master Nathan's cum. Instead, she quietly ran the tip of her finger over her husband's caged cock, gathering his precum and quickly smearing it over her lips without anyone noticing except him. Leaning closer to his wife, slave aaron whispered, "They're okay... It's okay..."
In the brother-sister huddle, new slave steven also whispered. "It's okay, sis. It just surprised me is all," he whispered in her ear. After a moment's thought, he added, "Do you still respect..." his voice trailed off for a moment, before trying again. "Are you okay - about - what i just did?" The fact that steven had been dribbling precum on the floor the entire time he had been sucking Master's cock had not been lost on either teen.
The younger sibling put her arm around her big brother, too. "Of course i still respect you, stevie!" Their faces so close together, they could smell the remains of Master's cum on each other's faces, as if His cum had scent-marked them. "Just saying... i'll try really hard not to call you a cocksucker... at least, except when you actually have one in your mouth." The grin on sandy's face forced steven to smile back, even though hearing his sister tease him with that word made him grimace.
The twins' private moment was interrupted as Mistress knelt and placed her face between the them. "Hello there, my horny young slaves. Time to pay attention to me, now."
"Sorry, Mistress," the twins said in unison, and returned to kneel on their heels.
"Tell me, sweetie," Mistress asked once the teenagers were giving her their attention. "Have you ever checked your pussy out in a mirror? Stuck your phone down there and taken a pussy-selfie?"
Remembering several such times instantly, sandy nodded her head.
"Use your words when asked a question, slave," Master Nathan now adopted the role of guiding the new submissive.
"Yes, Mistress Erin, i have - checked out my pussy with my phone," sandy admitted shyly.
"And what about other pussies? Have you checked out any of your friends? More than checked out? Have you eaten any of your friend's pussies, young sandy?" Mistress Erin delighted in her questioning.
"i - i - i have looked..." came her frank, stammered admission. "A few of us on a sleepover once... agreed to show each other... It was a while ago; we were just curious. But, well after that, there was one friend who was - more curious - and talked me into doing it again, one on one..."
Behind the naked twins, slave aaron couldn't contain himself. "Who was that?" he blurted out. "No, second thoughts - i don't want to know!"
Mistress tilted her head in slave aaron's direction, then back to sandy. "Who was it, sweetie? And is that all you did? Check out each other's cunts with your eyes?"
Realizing that she was committed, sandy continued. "It was Abby. Sorry, dad! Um, well, we kinda examined each other... up close... and then we showed each other how we - touch ourselves."
"How you masturbate, sandy? Is that what you are trying to say? Do you mean you showed each other how you masturbate your sexy pussies?"
"Yes, Mistress Erin," sandy admitted with a sheepish grin.
"And slave, did you and Abby touch each other, too? Or was it all show and no tell?"
In slave steven's mind he could picture Abby and his sister in her bedroom, masturbating as they checked each other out, and then cautious at each other, and then letting their hands stray across to touch each other. They must have felt so excited, stimulating themselves with an audience, exploring their bodies and learning about their differences and similarities. The images made the young man's cock twitch.
"One time, Mistress. She - masturbated - me until she made me, you know, cum... and then i touched her pussy too."
"What amazing things we are learning about our new pet, Master!" Mistress Erin smiled at her husband, before surprising everyone by turning to slave maryanne. "Now, slut - up on the sofa. Sit on a cushion." She directed the twins' mom. "Spread your legs wide, slut; you do that so well." Smiling at the obedience of her slave, Erin watched the mother open her legs, exposing her pussy to her children, husband, and her two owners. On the floor, slaves sandy and steven both watched Mistress giving directions to their mother, and both were thinking the same thing. If their first oral sex lesson had been learning how to suck Master's cock... why were they now staring at their mother's pussy instead of Mistress Erin's?
"Mmm, beautiful. Now - slave sandy! Up on the sofa, too!" Mistress commanded, relishing the moment, moving her pawns around the room.
With her head spinning a little with confusion and exhilaration, sandy stood, crossed over and sat on the sofa next to her mother. Without being asked, she slowly parted her knees, allowing everyone in the room to see her newly smooth, and very wet sex, drawing instant smiles of pride from Mistress, and Master. Noting the pleased smiles on her owner's faces, sandy allowed herself a moment to feel proud of herself for going above and beyond what her Mistress had asked. Sitting naked with her legs wide open felt very naughty to the teen, despite the fact that her own mother, who had taught her to be mindful of flashing people her panties, was herself sitting pussy-wide next to her.
