"Clean my mess?" He said, slightly appalled "You mean down there?"
"Yes, I mean down there." Haley said, rolling her eyes. "With your tongue, like a good boy."
"No way!" Chris shuffled away, hitting the wall behind him.
"Oh yes, you will." Haley calmly said. "You do want to do this again, right? Of course you do. I can see the desire in your eyes even now, despite having filled your cute sister with hot cum from both ends already."
Chris notably swallowed, she had him hooked, he wanted more of this more than anything in the world. The thought of her denying him now put his heart in a vice. He nodded.
"Good boy." Haley said with a smile. "Now get down there."
The boy reluctantly moved to sit in front of his sister. He looked down at her pussy, it was dripping with his seed still. A shake of his head and he leaned down. His tongue reached out from his maw and finally touched her soft fur, it was wet. Pushing himself he took a long slow lick, scooping up the mixture of their fluids, he swallowed quickly.
"Are you sure you can't just clean this off in the shower..." He said, feeling a bit defeated.
Haley just quietly shook her head. She loved watching boys lick up their creamy cum in the vids and here she was, watching her own brother licking his off of her, there was no way she'd miss out. She grabbed his head and pushed him down again.
"And remember to get all the way in there" she said and giggled "Make real good use of that tongue of yours."
She felt him lapping away at her with increasing speed, it was obvious he just wanted this to be over and done with. Every time he penetrated her with the tongue she twitched a little, it was quite different to the fingers and penis, softer, wigglier. After a while her brother sat back up again, licking his lips.
"I think I'm done..." he said "To be honest... when I stopped thinking so hard about what it was, it wasn't so bad. It tasted a lot of you too."
"See, you should listen to me" Haley said "I'm your twin, I knew you'd like it. No one knows you like your twin, right."
"I guess." He replied and blushed a little. "Maybe... maybe I should go back to my room now. I think I need a shower too."
Haley pondered for a bit, then the naughty grin returned. She looked over to the clock next to her bed.
"Well, there's still an hour and a half until Mom and Dad gets home." she said "And we already agreed that we should be safe still since I can't get pregnant."
"Y-yes, but..." Chris stammered.
"Don't you wanna feel what it's like to tie me?" Haley asked, interrupting his feeble protest. "Don't you wanna push that big knot of yours into me?"
Chris felt his cheeks flare up, his sister was like a different person, she was so lewd... so... sexy. He had regained some hardness while grooming her and now it quickly became fully erect again. He whined a little then pounced on top of her. He was shocked when she instantly pushed him off again.
"Sorry... I-I thought you wanted to..." he tried to apologize.
"Haha, don't worry." she said reassuringly "I'll fuck you, but this time I'm in charge."
Chris was pushed onto his back before his twin settled on top of him. She adjusted herself and slid the tip of his puppyhood into herself. He could only whimper and follow her lead. Was this how it was always gonna be, he thought. Haley bossing him around, controlling him, treating him like he was beneath her. He quietly hoped so. She started riding him and all other thoughts went out the window. They both breathed heavily. He looked up into his sister's eyes and saw that she was locking eyes with him too, as she swayed a bit from the movement. The warm wet folds of her vagina already kissed his knot with each push downwards. He beckoned her to lean over and she complied. He tilted his head a little and kissed her on the lips. Both of them were almost overcome with the intimacy this added to their act, a soft blush forming on their cheeks. They kissed several more times.
"I want all of you inside now." Haley whispered into his ear and waited for an approving nod.
She felt herself stretch further than she had ever stretched before, it was a bit painful but the pleasure took the edge off it. Another firm push and pop, it was in. It was her time to whimper a little, to keep it in she bit into Chris' shoulder. She felt her muscles hug tight around the knot and close around the base of her brother's cock. For a while they just lay there, blissfully connected in a way they had probably never thought possible, they were as one. Despite being wrong, it felt like the most right thing ever. They kissed again, not a word was spoken. She started moving slightly but at this point she couldn't really do much, she clenched around him again, doing her best to milk him from inside. He twitched now and then in response. Then she felt it, he started throbbing, twitching harder, holding it back, she knew. Again, no words, she just kissed him quietly and he released the flood for the third time that evening. His hot seed filled her in a completely different way now that the exit was blocked, she felt the warmth deeper than the last time. Though despite the natural cork some cum made it past and dripped out of her, down on his sheath fluff. They broke the kiss finally and she lay down on top of him and relaxed. Chris finally broke the long silence.
"This is the best day in my life." he said confidently "I had no idea when I got up this morning, but now I never want this day to end."
"You're so silly!" Haley said and giggled at how cheesy her brother was.
"I've always loved you, you know that right." Chris said, looking his sister in the eyes, suddenly very serious. "Even before all this."
"I've always known." She replied. "I've always loved you too, I've looked at other boys but they would never understand me the way you do. It's kinda sad it took you this long to finally muster the courage to approach me, even if it was just to peek."
"You could just as well have come to me" Chris said and bopped her nose.
"Don't be silly, courting in a man's job, so there!" she retorted and they both laughed.
There was a deep sigh from Chris.
"So what do we do now?" he asked "Are we, like, boyfriend and girlfriend now?"
"No silly, we're siblings" Haley replied "Siblings with benefits."
"That sounds strange" Chris said and giggled.
"You'll always be my first choice, Chris." Haley said "Always. But, I don't think I'm done corrupting yet!"
She laughed over the top maniacally at first and heartily after.
"But right now I think we need to get into the shower! Mom and Dad will be home soon and they must never know."
The end.
