Big Brother...

"It hurts?" Rinka asked, confused. While she had read some things about sex in hopes to do them with her big brother, she was still an inexperienced maiden far from being a professional slut.

"Un. It's hurt unless I can calm it down..." I looked away feigning embarrassment.

"Can I- Can I help big brother?" Rinka asked as her breath started to get ragged. The thought of doing a sexual act with the one she loves, sent her into heat. Something quite normal for the women of this world.

"Just... be careful." I blushed and turned my head avoiding eye contact out of shyness. Of course, this is just an act.

'Cute! Big brother is blushing. I don't think I'll be able to hold back...' thought Rinka before she started touching my body, her naughty hands going lower and lower. I match my breathing with her hard breaths, to show I'm just as into this as her. Something I noticed worked on her. Seeing the result of their seduction bear fruit would make any women slightly more confident.

Her tiny hand touched my cock, slowly and gently as if afraid to hurt it. She tried grasping it, but she couldn't fully grab it as it was as thick as her forearm. 'It's big!' she thought to herself. A debauched smile creeping up her face.

She began stroking it slowly, each repetitive movement caused her small breast to jiggle, attracting my attention to her little cherries.

As she stroked my cock, our eyes met, and we could both see the fires of passion within them. I leaned over and pressed my face to hers connecting our lips into a chaste kiss at first. My own hands began to get naughty as I pulled her closer with one hand and then began cupping her breasts and pinching her nipples with the other.

"Ahhn~" She lightly moaned and when she did, I deepened our kiss into a sloppy tongue kiss. Our movements became wilder as my hands roamed her petite body, lightly brushing against her erogenous zones but not over stimulating them all at once. I want to give her a slow and powerful buildup before her first real climax. Something that will dye her mind completely white for a moment.

Her hands were both pumping my cock before we finally stopped kissing. I pulled her up as I lay down on the shower floor. "Suck it!" I commanded her which caused a shiver down her spine and with my face in her crotch I saw her love juices dripping from her little pussy.

Her cute mouth went down and she started by licking the tip and giving it a cute little kiss before licking up and down the shaft.

I licked my lips at the meal in front of me and with two fingers I spread her private place and found her jewel. The tip of my tongue poked out and pressed her cute little bean, which sent a jolt up Rinka's spine.

"Uhh... Big brother, I feel... Ahhn~...so good." Rinka was beginning to feel pleasure and it was like a dream for her. Her big brother, the person she loves is licking her tiny virgin pussy like its a delicious candy. 'I-I need to make sure to please him too!'

Rinka went to work on his cock while eliciting soft moans as she sucked. Bobbing her head as she experienced multiple light orgasms from her beloved brother's tongue.

I wriggled my tongue around her exposed clit and one of my finger's curls inside her pussy seeking her g spot. My finger was being squeezed hard and I was getting even more aroused thinking about fucking this tight box.

"Mm... Ahh~...Big brother, something big is coming~ I-I can't!"

"Hold it as long as you can Rinka. If you do, I'll give you a reward."

"O-Okay... Hii...Um..." Her whimpers were getting closer and closer. My balls were also itching for a release, so I sped up my work. I licked with a faster pace circling her bean in even motions. Rinka's body began to twitch, signaling her incoming climax.

"Ahhh!~ Coming~ Ahh~ Ahh~ Almost... UGHHH!~ With an explosive burst, her climax sent a wave of her love juices onto my face, her mind blanking out momentarily from the pleasure. At the same time, I grunted and pushed my hips up to get my dick further into her mouth, giving her a reward.

*Splurt*

Rinka was too dazed to realize I just spunked in her mouth, and she subconsciously began to swallow before realizing what happened. "Mhm~ Big brother's seed! Delicious!" Her slutty nature on full display before me as she eagerly drank every last drop and then even started cleaning my cock again with her mouth.

She released my dick from her mouth with a *plop* sound. "~Thanks for the meal, big brother! ~" She said as her climax also died down. Her skin was flushed on her petite but sweet body which created a seductive look as she was glistening from her sweat.

"Glad you liked it sis. But... It still hadn't gone down yet.~" I said teasingly causing her to look down at my cock again.

"Wow~ So lively, I thought guys needed a break between climaxes?"

This slutty sister of mine arched back and wriggled her ass in front of me as she began sucking me again.

*Slurp*Slurp*Slurp*

The debauched sounds of her mouth as she bobbed her head up and down my cock aroused me further, so I grabbed her hair firmly and started face fucking her slutty mouth. The end of my cock reaching into her throat as she throated me with only minor trouble.

I could feel my cream rising to the top with each thrust.

"I'm gonna cum, sis. Make sure not to waste any of it!"

I rocked my hips back and forth and I fucked her mouth. Her hand was already on her crotch and was moving vigorously.

"Rinka! I'm cumming!" I gave her a warning, and she looked up into my eyes and gave me a silent confirmation.

*Spurt!*

Ropes of jizz shot directly into her throat, right as she had climaxed, causing the vibration of her body to massage my dick sending even more pleasure through it. Gulping sounds were heard and she pulled back off my dick and opened her mouth, showing me she swallowed it all.

"I could get addicted to this big brother~..."

I know you could... I've seen it...

I pulled Rinka into the bath and held her in front of me. She just kept giggling to herself and humming while leaning her back against my chest.

"Big brother, does this mean you decided to marry Rinka?"
