Nana bit on her lower lip to hide a chuckle as she felt Tsuna quickly erupt seconds after entering. Well ... that did confirm the other thought she'd tucked away into her head. Yes, it seemed she
would still need to include that in their evening play also. No matter and who knew? Maybe Tsuna would enjoy it after a bit. Either way, he'd thank her for the training later, in some form or fashion. Nana licked her lips, moaning and cooing at both the physical pleasure she was feeling and just envisioning all that was yet to 'come', literally and figuratively.
"Mmmmh, you feel so warm, sweetie. Good boy, yes! Take your fill!"
Nana thrust her hips back, helping them collide with her son's. After a few well-placed movements, including guiding his cock along her sweet spot, Nana shuddered as a long groan elicited from her lips. Her body tensed up .... as she threw her head back, gushing and cumming all over Tsuna's eager member, rutting back faster as she started driving herself over in multiples. "I'm going to enjoy you as much as I possibly can before we gang up on that sweet little slut of ours!" she growled, clamping tightly as the second of many orgasms coursed through her body.
Tsukiko, meanwhile, was still holding tightly on the sheets of the bed, gripping them as if she were holding onto her very life if not soul. She was already close to another climax ... and that only strengthened when she heard her mom scream out and reveal that whatever the video was, it was likely naughty in nature. Oh, if only she knew just how accurate that guess was, and the irony included with it!
"Fuck, daddy! Y-You're making it impossible to not cum .... mmmmfff!!"
Tsukiko could tell that even if she weren't moving her hips along his eager cock, she'd still be a whimpering, writhing mess coating his member with little to no trouble. More whimpers and coos resounded as Tsukiko slammed back, seeming just as happy with the sex as her father was before her body tensed up. "Agggh! Daddy!!!!"
A few seconds after her body caved in, Iemitsu finally did also. Tsukiko slumped onto the bed, her elbows just barely managing to support her. There really was something intimidating yet erotic at noticing that if time weren't an issue ... he probably could plow her all day and night if he so desired. Maybe ... maybe one of these days, she may be able to test that theory out. For now, she noted how good his control over his orgasms were versus her own ... and started at least
trying to tuck some ideas and hints away.
But more than that ... her body was enjoying the afterglow both herself and Iemitsu were enjoying ... as well as the rest of their session.
Eventually, though, Tsukiko would be called down to help with dinner; something that Iemitsu encouraged her to go down and assist with, though not before giving her ass a light smack while she got dressed and exited his room. After the thorough session she'd had with her father, Tsukiko most definitely had worked up an appetite and otherwise had no objections helping her mom out.
"Taking it you had fun with my husband?" Nana asked, causing Tsukiko to nod while blushing. "Good. Then you'll
love tonight. I've waited for my turn, and I fully intend to make sure it was well worth planning over the last two or so days."
That confession certainly made Tsukiko go quiet as she took a few moments to go over the confession in her head. "H-Hold on," she stated, an eyebrow raising. "So ... you're telling me that ... you've ... w-wait, but ummm ... how are you ... ??"
Nana merely smirked as she wagged her finger in response. "Soon.
Very soon you'll find out. That said ... I suggest you eat up. You'll
need your energy."
After everyone gathered at the table and ate up, Nana would gather the dishes. The twins would notice Iemitsu going off in a different direction that was
not his bedroom. Before he vanished, though, Nana would give him a passionate kiss on the lips. Once both women were done with the dishes, Nana hummed happily as she damn well nearly dragged Tsukiko into the same bedroom she'd been in not long ago.
"In here, Tsuna!" Nana would call out, grinning widely from ear to ear as she pointed down towards the bed. "You ... you sit, my dear." Despite the cheerful tone in Nana's voice, there was a commanding undertone that didn't escape Tsukiko's ears. Without a second thought, she sat down, causing Nana to lick her lips and pat her daughter's head. "Yes ... very good girl. This'll be
amazing! I can already tell!"
While they waited for Tsuna, Nana began rummaging under the bed, humming happily as she pulled a bag out. She reached in ... and smirked as she set down an array of
leather collars on the bed. "Now," she began to explain, "Like I said ... your day one Tsuna got you? That's for you to wear out and about in public. But these? These are for evenings like tonight. I meant it when I said I have zero intentions of half-assing my position as a Mistress, and that comes with having you wear a proper collar for sessions like these. You can use safe words if you ever need to ... but any rules or commands I may give? I expect them to be followed, as will your father, I'm sure. Had your father decided to put one on you earlier, he very much would have. But he knew what I had planned and allowed me to have the honor of giving you your first one of these. So ... lift your hair up."
Tsukiko just stared as she complied, noting each of them had a label of some kind on them. Some more tame like 'SLAVE', 'KITTEN' or 'OWNED'. Others were pretty crude and had words like 'SLUT', 'DADDY'S LITTLE SLUT', 'WHORE' and other similar terms of the like.
Tsukiko would look down at the new collar ... noting this one read 'BITCH'. She chuckled nervously ... and saw Nana merely smirking. "O-Okay ... I'm clearly missing something, aren't I? Wh...what's going on?"
"Shhh. No need to be nervous, for one. Okay? Did you like this?" Nana would resume petting her daughter's head. Tsukiko let out a sigh, nodding as her body did indeed seem to calm down. "Okay then. You can get more pets, because I definitely want you to enjoy this, not be scared or anything. This was just kept away so it could be an even better surprise."
Only after a few moments would Nana finally stop and give her attention to Tsuna. "You too, sweetie. Sit." But whereas she'd pointed to the bed with Tsukiko, that would
not be where Tsuna was guided. If anything, Nana pointed to a chair beside the bed. Once he complied, Nana stood up and grabbed some items from a nearby nightstand that, if either took the time to notice, were laid out in preparation for tonight. Some silk sashes.
Wordlessly, Nana began tying Tsuna to the chair, smirking as she eventually finished. "Don't worry, I'm not an expert. But I know enough basics, at the bare minimum."
Tsuna would feel easily enough what she meant; the bindings weren't tight enough to risk cutting his circulation off. But a few struggles against the restraints
would show he wasn't going anywhere anytime soon, either. With him helpless and unable to stop her, Nana was free to resume with the next parts of her plan - the parts she'd kept hidden from Tsuna. "If it helps, Tsukiko, I kept your brother in the dark about this portion of what was going to happen tonight. So you're not the only one who was left in the dark, so to speak."
Tsuna's pants and boxers would be undone, revealing his cock. Regardless of whether he had been any bit aroused or not ... Nana worked on fixing that as she swiftly went to work sucking him off, using her skilled tongue to go over his sensitive veins. Once he was erect enough .... Nana would stop, pulling another item. Circular in shape, black in color. It certainly looked innocent enough.
Even Tsukiko was curious ... and blushed as Nana placed it snug around Tsuna's member, letting it rest near the base. She gently pushed down ... and Tsuna would feel it gently begin to buzz and vibrate. "There we go~" Nana cooed, smiling as she watched Tsuna squirm and react in the chair. "You are going to help like I promised," Nana reassured him, "But before that ... you need to work on building yourself up more. It's an unwritten rule, but usually the man makes sure the woman gets off first. You failed with that when we were downstairs. So ... this will help you with your stamina. Think of this as training, not punishment. Now then ...."
Nana moved in front of Tsukiko, tiling her head up ... and leaning down into a passionate kiss. She stabbed her tongue inside, taking advantage of the poor girl being too shocked to try to fight against it. Groaning in delight, Nana pulled away after a few moments, petting Tsukiko once again as she stared at her daughter. "I do believe you were trying to ask some questions about how this would work earlier, right? First off ... let me backtrack to last night when you used that toy I gave you. I'm sure it didn't escape you it ... seemed to gain a mind of its own."
"Yeah, so ...."
She stopped as Nana held a finger up, revealing she would explain now. "Sun Flames are my natural ones. Truthfully ... we've toyed with the idea of getting active with you two for at least two years. But we wanted to make sure everything was right, including timing and prior to this vacation, your father was always away at work. But because we wanted to do something like this at all ... your father came up with a very nifty invention. He and some of the others in the CEDEF have found ways to transfer Flames into any item you want to use. So ... he gave me these Mist earrings. And
that is why your toy reacted that way. Of course, the Sun I told you about was also part of the equation ... but not all of it like you may have guessed."
Tsukiko nodded in understanding.
"Now ... do you even know what kind of cock that was, baby girl?"
"N-no, but ... it didn't seem human."
"Mmmh, smart girl. You're wearing the answer."
"Huh?" Tsukiko glanced back down at her neck and took note of the collar. "W-wait, what?!"
"Mhmm, that's right. You took a nice, canine cock right up that twat of yours. Since you loved it so much ... I figured I'd give you a replica of sorts of the real thing." And as Tsukiko lifted her head, she found herself staring at a throbbing member inches away from her face. Sure enough ... the knot was there. The shaft of the red member already throbbing in anticipation and excitement.
Nana licked her lips ... then gave a simple nod downward, followed by a single word. "Suck."
Tsukiko opened her mouth ... and only hesitated for a few seconds before taking the waiting rod into her mouth. Nana sighed and groaned as she used every ounce of willpower to stay put, allowing her to go at her own pace for now. Much like her husband would have encouraged if he were here. But dear gods ... her mouth was even
better than Nana had ever fantasized about!
Oh yes, now there was no question whatsoever. She didn't
think she'd enjoy tonight. No, she knew she would. "Mmmmf, yes! Get ready! On your hands and knees like a proper bitch! Show yourself off to your brother! He'll be joining in when I let him."
Tsukiko blushed ... but complied as she assumed the proper position. Even reached back and used her right index and middle finger to spread her pussy open, showing she was already moist and drooling a bit, causing Nana to growl in pleasure ... and then give her ass a light smack. "Ohhhh, yes! Mmmm ... nights like this will be even better and more fun when your father and I start training your backdoor. Ohhh, until then .... we'll eagerly to town on that slutty cunt of yours."
