A Body Shaped Crease in the Sheets (Ending)

Claire fell asleep holding her sister close. She didn't want to fall asleep, but three orgasms and an evening full of even more excitement can really be a drain. She reached over for her sister but felt empty sheets and peeked through lazy eyelids to find the empty space in her bed that never seemed so empty before. She missed Mia already, so she bolted upright and stared towards the open door. The night was still and Claire could just be sleeping since the hour was earlier than any sane person would wake.

But wake she did.

She tiptoed down the hallway until she could hear the stifled moans and the acute slapping of flesh through the closed door into Ryan's room. Yesterday's Claire would have filed it away, gone to sleep. This Claire noiselessly turned the handle and watched as Ryan's massive cock rammed into Mia from behind.

Mia moaned out, "Grow penis grow..." and her eyes rolled back into her head as her pussy visibly stretched around her brother's growing cock. Claire was unable to pull her eyes from the scene. Her fingers crept down to her own entrance, unable to contain herself, her desire for Mia building inside her. It was too hot for Claire to handle. In all of the thrusting Claire found her fingers pumping in and out of her vagina to the same pattern before her; her thoughts drifting to Ryan's strong arms and powerful thrusts, wondering if she could take that much of his cock. It was almost insanity to watch as Mia's body contorted, cumming in a way that seemed foreign from their intercourse, but just as raw.

She had decided. She couldn't just watch anymore. She crept into the room, shutting the door softly behind her and locking it. Ryan's head turned to the click and Claire just held her finger to her lips. Ryan nodded and continued to fuck Mia senseless while Claire came up behind him, wrapping her arms around his strong body. She whispered in his ear, "Doesn't she look so sexy like that?"

"Fuck yeah." He moaned. "She's beautiful."

Claire nibbled on his ear and gently massaged his balls. He shuttered. "Why don't you go bigger?" She teased.

"Why'd you join us?" He teased back, not answering the question, sweat beading on his skin.

Claire gripped him tighter and rocked with him, laying her head against his. "She may have changed my mind on things..."

He nodded, grunting as Mia pushed back hard on him, turning her head and smiling at the two of them chatting while she was fucked. It was a giddy smile that spoke to see how happy she was to see them together.

"I didn't want to hurt her."

"You won't, plus she'll like it."

Ryan grinned like a goofball and Claire squeezed his balls extra hard while she said the words three times. Ryan reached a hand back and squeezed Claire's ass playfully while he felt his cock rearrange Mia's insides.

Claire wrapped her hand around her brother's arm and kissed him deeply. "You like that big boy?"

"I love it." He spoke into her mouth.

"You know... I'm next, right?" She whispered in between kisses.

"You think you can handle this cock?" He grinned.

Claire gripped the base of his shaft... well, attempted to. Her hand simply couldn't wrap around it. "Not right now little bro..." She said with a bite. "I don't think it'd fit... you'd probably kill me."

"Well, we can take it slow..." He winked.

"Or just take your time with Mia and I can find other ways to occupy your other faculties." She whispered, seductively then out of nowhere she pushed him down onto the bed lifting Mia up on top of him before Claire settled her dripping snatch down on his face.

Mia did the monumental task of turning around on Ryan's cock to face her sister. "Glad you could join us." Mia said through contorted features.

"Me too." Claire smiled coyly.

"I feel so fucking full." Mia moaned.

"You're welcome."

"Just shut up kiss me."

"Gladly."

"Fuck yeah bitch." Ryan joyfully, said as he got to work on his sister's pussy, slapping her round ass gleefully as he looked forward to making her cum. It didn't take long as no sooner had the words left Ryan's mouth than his sister violently came on his face.

Mia watched as Claire's eyes rolled back and her tongue fell out of her mouth in a perfect ahegao face. Her body shook and liquids spilled out of her onto Ryan's eager mouth. Mia held onto her as Claire came, caressing her face. Turns out you are extremely stable when your body is supported by a tree trunk.

"What was that Mia?" Asked.

"I don't know..." Claire sputtered out after her body recovered from her incredibly strong climax.

"I don't either, but I liked it." Ryan chimed in, as he resumed licking his sister's slit.

"I think I just came on command... and..." She rocked her body for a moment, enjoying Ryan's lips on her warm and wet clit. "... I think I've played the game before."

"Well, I can say your phrase and you can say mine." Ryan said as he thrust into Mia, begging her to resume bouncing her stretchy body on his cock... which she did.

"You will not!" Claire gripped twisted Ryan's nipple and gripped his ear.

"Yes, mam."

"This stays between the three of us."

"Among other things..." the twins chimed out in unison, causing them all to laugh and when the laughs died, they resumed their fucking with a renewed appreciation.

Claire smiled as her brother's tongue softly pulsed inside her and moaned when it sometimes poked at her asshole. It felt good to be kissing Mia again and even better to watch as her siblings shared each other with such joy and desire. She couldn't wait for her turn, but this somehow felt just right.

When she woke up curled up into heap with the two of them, finally stuffed full of cum by her brother and enjoying it, she wouldn't take them for granted. She wouldn't leave them here or separate her family from her friends any more. She wouldn't separate her internal desires and feelings from who she was on the outside. It wouldn't be either one part of Claire or the other. It would be both.

P.S. Thanks to everyone who read through to the end. I've been wanting to finish this for quite some time and I had this ending in mind since about half way in. Regardless of if life happens to me rather than for me I am happy to have an ending to this story.

XOXO Much love.
