I woke up with a groan, but not my usual one.
It took me a moment to realise that I wasn't having a wet dream, and that there was in fact something warm wrapped around my cock.
Pulling back the blanket revealed a hood from a familiar onesie, and my underwear shoved between the mattress and the wall. She didn't even look up as I pulled the blanket off the both of us, head just bobbing up and down.
"Good morning." I said breathlessly.
Rin giggled briefly, and then continued to blow me. Leaving me uncertain of her intentions. She might just be getting me ready for something else, or she might be trying to make me cum.
Either way, it felt amazing.
The red sunlight of the dawn was still peeking around the edges of the curtains. Making the room glow as I basked in the feeling of Rin's expert tongue on my cock.
She'd taken a risk, waking me up this way as a surprise... But I fucking loved it. "Mmm. Shit, yes."
Rin pulled her head off my cock, letting out a mouthful of drool that she quickly pumped along my length and looked up at me, "Feeling adventurous?"
"Depends." I frowned, "What did my wife have in mind?"
She shuddered, "Fuck. Oh, I love it when you say that. Just a second."
Rin stood up and pulled her onesie off quickly, revealing her perfect naked body. She grinned at me and touched herself, "So wet. So naughty. Getting all riled up on you whilst you were asleep."
"Want to get on top, then?" I asked her.
She shook her head, "Uh uh. Not yet. Adventurous. I may have bought some other fun things yesterday. Would you mind... Tying me up?"
I blinked as she bent over and pulled some soft black silk ribbons from a bag and began twisting them around her wrists. "You into that?" I asked in surprise.
"So much." Rin bit her lip, "You... Didn't answer. What about you? Pleeease?"
I climbed off the bed, giving her the space to lie down.
Sat over her, my wet cock dragging across her navel as I reached up to her raised arms. "So, do I tie this up tightly or...?"
"Just a loop." Rin said, "I need to be able to pull free if there's a problem or something. But I'll pretend I can't. That's why I'm holding them. You really never tied up a girl before?"
I tied the ribbons up so that she'd be able to slip her hands free, but that they should stay put if she was just pulling against them. "We used handcuffs. Bruised my wrists."
"Ooh." Rin said excitedly, "She tied you up? You... Like it?"
"Yes and no." I shrugged and then kissed her neck, and began to kiss lower until I got to her breasts. I suckled one of her teats, causing Rin to arch into me, "I like biting. Being bitten. So, I do like a little pain. Certain kind of pain. Hated the handcuffs. Might like ribbon."
"I knew you... Fuck. Shit... Wanted to bite me." Rin groaned, "I'm into it. Yessss... Not so much the... Oooh. Makeup to cover the bruises, after. But worth it. Oh... Eat me?"
I brushed my teeth against her leg, and then nuzzled down into her sex. Flicking my tongue at her clit. A glance lower told me that she wasn't just wet. She was already dripping onto the bed.
Teasing was part of the excitement of being tied up, though. So I drew things out by licking inside of her. Using my fingers to make her groan and moan, as she clearly tried to keep things quiet.
As my hand continued to run along her insides, I shifted upwards and put an arm behind her shoulders. I pulled her down, stretching her arms and causing her to gasp, before pushing my mouth roughly against hers.
Rin moaned loudly into my mouth, shuddering as I felt her cum on my hand. I continued to work on her, saturating the sheets as she overflowed. "You're mine."
She swallowed, "I'm... Fuck... Yours."
"How do you taste?" I asked her and kissed her again. My tongue playing with hers, teasing the tops of her teeth before I pulled away, with Rin sucking at my tongue to try and hold onto it.
She breathed heavily, "More."
"Uh uh. I asked you a question." I pulled my hand from inside her a moment to suck on a finger before pushing it back inside her. "How do you taste?"
"Fuck... You love this." Rin glared at me, and then shuddered, "Oh, you're going to make me... Cum... Again. I like it. Okay? I like... Shit... Tasting me... On you... Fuck."
I withdrew my hand slowly and offered it to her, holding my hand just out of reach, so she had to stretch to reach. Which she immediately did. Pulling on her bands to lift her head and suckle on my finger, sending a thrill through me.
Rin was loving this, being ever so slightly dominated.
I desperately wanted to take it to the next step, and fuck the daylights out of her. However, she was trusting me with this. I had to reward her, play into the fantasy.
My hand returned to making her shudder and moan, and I kissed at her cheek, "Do you have any more of those ribbons?"
"Ugh... Yes... A... Couple... Fuck yes... Oh, I'm close... I'm going to cum... Again." Rin arched into her bonds.
I pulled free, stopping mid-orgasm and making Rin give a frustrated moan before she kicked the bed, "Hey! What are you doing?"
I pulled open her shopping bag, and saw so many things she probably hadn't planned for me to, just yet. I tried to ignore most of them and grabbed a couple more of the ribbons and turned back to her.
I gently looped one of them around one ankle, and then tied it to the metal ladder at the end of the bed. I took a moment to kiss along the inside of the now partially immobilised leg.
"Oh god." Rin shivered, "You're really doing that?"
"Do you mind?"
She laughed nervously, "No. No, I do not. Can you stop taking your time and fuck me?"
"Nooope." I replied as I began to tie up the other ankle to the edge of the bed frame.
With that done, I climbed in between her legs, leaned down and slid up her stomach, relishing the skin-on-skin contact. I paused when I was high enough to kiss at her breasts.
Rin mewled, moving her feet and tightening her grip on the ribbons in her hands. "Oh, come on. I really, really want you. Pleeease? Put it inside me?"
I put my arms behind her, holding her as I kissed between her breasts, "Put... What... Inside you?"
"Oh, fuck. Fuck you." Rin growled, "You want me to beg? I'm begging. Pleeeease. Pleease, Chris. Please fuck me. Fuck your slutty sister. Fuck your naughty wife. Just fuck her. Pleeeease."
"Don't call yourself a slut. Ruins it." I said and then kissed at her again, "But... Beg me. One more time."
I leaned up, and began rubbing myself up and down her entrance, "For me?"
"Pleeease, Chris?" Rin said, staring at me with her glittering emerald eyes, "Please, take my little cunt. Fuck my snatch. I want it. I want you, so bad. I want you to fuck me so hard. Fuck me so I can't walk. So I just curl up on the couch all day. I want to feel you pressing down on me. When you're ready, you'll fuck me again, and again. Use me all day. Make me yours. Pleeeeease."
