Chapter Summary: Turns out that having sexy time in the morning isn't good enough for these two teens.
Chapter 2: Afternoon of debauchery.
Len opened his eyes slowly, taking in the view of his bedroom ceiling and feeling the weight of his twin sister laying on top of him, her head cradled in his arm's embrace.
He smiled to himself, remembering that he and Rin gave their virginitys to each other and softly stroked her hair as he looked over to the digital clock on the nightstand next to his bed, seeing that it read 1:27 P.M.
Rin then mumbled something as she began to stir and raised her head, wiping her eyes and looking at her brother below her.
"Why good afternoon sunshine. Did you have a nice nap?" Len flirted with a big grin on his face.
"Yeah, but only because I'm with you." Rin flirted back as she hugged him close, feeling their naked bodies together.
"Len, that was so much fun. You're the best brother ever!" She exclaimed, snuggling him.
"Awww, you're so sweet." Len replied before kissing her forehead.
Rin smiled and lifted herself up and climbed off him and bed.
"I'm going to get a drink." She said.
Len leaned up and stared at her cute, tight butt as she walked out of his room and headed downstairs. Smirking, Len sat up and decided to follow after her.
Reaching the bottom of the stairs, Rin strolled into the kitchen, opened the fridge, feeling the chilly air escape and cover her naked body in goosebumps before grabbing a water bottle and closing it. As she gulped down her beverage, Len walked in, sporting an erection.
"Is it uncomfortable when it's hard like that?" She asked.
"Yeah, but when you started licking it and when we well, 'did it' it felt like I was in heaven." He replied.
"Wow. I kinda felt the same way, my cunnie would get wet and I felt like I had an itch inside that needed to be scratched. And my button would get stiff too, kinda like your dick does." Rin explained, using two fingers to spread her lips and looked down at her clit.
"You know, it's only Sunday, we don't anything planned for today. Maybe we could spend the rest of the day just... you know." Len said sheepishly, scratching the back of his head.
"You mean, just have sex all day?" Rin inquired as she sipped her water.
"You don't mind?" He asked.
"Hell no! I'd love that! C'mon!" Rin exclaimed excitedly, setting her water bottle on the counter and grabbing Len's arm to drag him back upstairs.
"Hey hold on! What's the rush? We could do it down here." Len tried to explain.
"Like maybe on the couch in the living room?" Rin asked while tilting her head.
"You wanna?"
"Hell yeah I wanna!"
Rin then dragged him over to the living room couch and had him lie down while she climbed on top of him in a 69 position.
"Cool huh? Now we can lick each other!" She said before taking Len's penis in her mouth and began sucking.
"Dope." Len said, before shoving his tongue into Rin's snatch.
The twins both moaned loudly as they continued using their mouths on each other, Rin licking circles around the glans of Len's dick before sucking on it entirely while Len shoved his tongue in and out of her drenched pussy, practically fucking her with it and occasionally nibbling and sucking on her clit.
"Geez Rin, you're so wet." Len commented as he shoved his index finger into her opening and twisted it around.
"And you're so hard." Rin retorted as she jacked off his dick and lapped at his balls, sometimes even sucking on one of them.
Soon she began grinding her hips into Len's face as her climax drew near.
"I'm cumming Len!" She cried out as her juices covered his mouth.
"I'm cumming too!" Len cried as he sprayed his cum all over Rin's face.
Rin lapped up every drop she could get, although she needed tissues to wipe up all the spunk on her face.
After throwing them into the garbage she turned to Len back on the couch.
"You ready to go again?" She asked.
"You tell me." Len replied smirking as he looked down at his dick.
It had gone soft after his orgasm, but now it began to stretch and stiffen again. Rin giggled and straddled him, grabbing his dick and pointing it up to her pussy and slowly lowered herself onto it, moaning.
"Ahh, so tight!" Len hissed.
"Ahh, so big!" Rin squeaked.
And with that, Rin began to ride him again, bouncing up and down, up and down, sucking his dick into her womanhood repeatedly. The twins both moaned and called each other's names as Rin switched it up by rocking back and forth, grinding herself on Len's penis as they locked hands.
"Rin you're so hot." Len panted out.
Rin chuckled to herself and started talking dirty to him.
"Yeah, you love this don't you? You love it when your sister bouncing on your lap, sucking your dick into her hot pussy don't you? I bet you wanna cum and fill me up with your semen. You wanna cum Len? Does Len-kun wanna cum?"
"Yes! Yes! I wanna cum in your pussy Rin! It's coming right now! Oh god yes!!!" Len cried, thrusting his dick as far into Rin's pussy as he can and released his seed into her, making his twin cum as well.
As they both stopped to take a breather, Rin climbed off Len's softening dick and Len sat up to pull her into a kiss.
While they kissed, his dick quickly stretched back out to it's full length, ready for more.
Breaking the kiss, Len had Rin get on all fours as he stood on his knees behind her, gave her a good smack on the ass making her yelp before positioning his dick at her entrance again.
"Oh my god, we're gonna do it like dogs?" Rin giggled, her face blushing from such a naughty position.
With one hand gripping Rin's hip, and another gripping his erection, Len thrusted into her and went wild, slamming into her again and again as she cries out in ecstasy. Feeling Rin's butt bounce into his crotch with every thrust, Len leaned forward, wrapping his arms around her torso and took her tits into his hands while also kissing and sucking on Rin's neck, leaving a hickey.
"Oooh Len, you're reaching so deep inside me I can feel you hitting my womb." Rin moaned out, although they weren't exactly moans, but more like mewls coming from a cat in heat.
"Yeah, you like it from behind don't ya? Take it then! Take it! Take it until I explode and drench your pussy in my hot cum!" Len growled out, hammering into her like a piston running at mach 5.
Like a bolt out of the blue, Rin's orgasm hit and she screamed as her pussy contracted making Len's orgasm hit as well, his hot cream overflowing in Rin's cunt.
Hot and sweaty, the twins fell on their sides as Len slipped out of Rin while they both tried to catch their breath.
About 3 minutes later, Len sat up and stretched out his arms before sniffing his underarm and gagging from the musky scent.
"Man, I need another shower." He says as he gets off the couch and starts walking to the stairs.
"Oh! Lemme join!" Rin calls after him, needing to wash the semen out of her pussy and following his lead.
The both of them headed upstairs to the bathroom where Len started the shower head, while Rin grabbed towels for themselves. When the water heat was just right, Len stepped inside, Rin following right behind him.
The siblings both took turns washing each other, Rin getting Len's back, Len getting hers. They then shampooed themselves and took turns rinsing their hair out.
After they both shake their heads, making water splash everywhere like a dog would, Len felt his penis stiffen again.
"Rin, turn around." He told her.
She complies and puts her hands on the wall of the shower and sticks her butt out towards Len while he gets behind her and shoves himself into her womanhood for 5th time that day.
"Ahh yes!" She cries out. Len soon starts humping Rin's pussy vigorously, muttering her name with every thrust.
"Oh Len, yeah! Give it to me! Harder! Harder!" She says, urging her brother.
With her encouragement, Len just completely goes nuts, and absolutely slams Rin's cunt as hard as he could, making the both of them cry out each other's name.
"Rin!!!"
"Len!!!"
"Rin!!!"
"Len!!!"
"Ri-ahhhh!!!!"
"Ahhhh!!!" And with that, they share their biggest mutual orgasm yet, as Len pulls out and sprays his load all over his sister's back.
After catching their breath, Rin turns around , and they embrace for another kiss before rinsing off one last time, and stepping out to dry.
End of Chapter 2.
