(Lol writing after I lost my virginity so let's see if my writing changes a little)
"Are you rea-"

"Can you help me tie the back?" I asked Mikasa as she barged into my room without realizing I was in the middle of putting my bikini on.

My back was facing her and I was struggling at tying the fabric myself. "Sure." Mikasa walked from behind me and replaced my hands on the bikini piece.

I could feel my body temperature heating up at proximity of her bodies. I felt her fingers start to trail down my back faintly after the knot was already tired. My body went cold at the sensation of her soft fingers delicately grazing me. For a second I felt a slight hint of a need to explode my body but was shortly interrupted with her voice. "There, you can turn around now."

Her eyes met mine when I fully positioned myself toward her, then they left to stare down at my half naked body. I suddenly started to feel shy when I realized I was almost exposed and she's never seen me like this before.

The focused gaze with a hint of interest had me ready to beg for her to touch me.

Oh how bad I wanted her to rip my bikini off of my body right now...

"Where's your bathing suit?" I asked her as she was wearing a white wife beater and jean shorts with no hint of bikini straps.

"Oh I'm not going in the water. I'm not really a water person." "Really that's a shame, you have the perfect strong legs for swimming. We should go now." I said trying to hide my disappointment.

The water looked beautiful and clear and I felt like a little kid again pretending to be a mermaid. I threw my slip on dress off as quickly as I could ready to jump in right away  as Mikasa set up an umbrella.

I ran towards the ocean and didn't even react to the temperature of the water. I swam around before jumping back out and leaping towards Mikasa persuading her to swim with me.

"You have to go for a little it feels so nice and it's such a perfect dayyyyy, pleaseeee," I pleaded like a child.

"Will you shut up if I do?" "Maybe," I said with a wide smile. Since she didn't have a bathing suit underneath she had to go in her panties and wife beater. 

I grabbed her by her hand and dragged her across the sand to the water before she let out a squeal and recoiled. I couldn't help but smile at how cute and small her squeal sounded when it came from such an intimidating monotone person.

"It's so colddd." She had her arms crossed in attempt of shielding herself. I suddenly pulled her down into the water with me before she could say anything as she let out another yelp.

I giggled as I saw her wet hair fall over her and pushed it away from her eyes from her which felt too intimate.

She splashed water at my face and I let out a very unattractive scream. When I looked up I saw her actually smiling which made me smile back.

That's when I noticed her shirt became see through since it was white. I couldn't help myself but stare at the outline of her perfectly shaped bosom and her rock hard nipples that seeped straight through. Her abs were also completely see through around the tight shirt that blended right in with her skin. I felt so close to her to be seeing her exposed like this. I wish I could see her like this every day, and only me.

I didn't realize how entranced and aroused I was. I tried hard to keep my eyes on hers but it was so hard when all I could think about was licking her from lips to lips.

The ocean water glistened her skin giving it a shiny affect. I just wanted a taste of her skin.

Before I could realize, a wave came in at once and overpowered me.  "Y/n watch out!" Was the last thing I heard before ocean water clogged my ears and surroundings. Since I didn't see the wave coming I didn't have time to hold my breath causing it go up my nose which made me struggle even more to catch my breath. I choked on the gross tasting saltwater and tried to catch my balance.

My eyes shut close and I was starting to slip away into a distance before I felt my body be gripped and held on while across the water path.

Luckily for me, but not surprising, Mikasa knew CPR and resurrected me back to life.

I woke up with a blurred memory at first with her lips on mine not helping me grasp what was going on until she pulled away. For a short second we held a deep gaze before the moment was completely ruined by me spitting water straight at her face.

"I'm so sorry-" "No it's okay, don't worry about it." She grabbed my arms helping me up to stand. "I feel light headed," I said losing my balance again. Mikasa caught me in her hand and sat me down. "Yeah you should probably just sit and relax for a while. Do you feel okay?"

"Yes, I'm just dying of embarrassment," I awkwardly chuckled. "That's never happened to me before, I'm a good swimmer I don't know how that happened."

"It could've happened to anyone, you were just caught off guard."

"Thank you," I said meeting my eyes back with hers. 

I rested for a while before I heard Mikasa's voice again. "I made you something," Mikasa said childishly pointing at the sandcastle I didn't realize she was working on this whole time. Of course, since this woman literally does not have one flaw, the whole structure of her sandcastle was built firmly and perfectly.

She couldn't know how much something this childish meant to me. "Aw, that's so sweet! It's cute. What do you think of the beach now?"

"It's nice," was her answer. Simple response but not for her.

"Oh my god I almost forgot, before we go we have to collect seashells. I use to collect them and make necklaces out of them," I claimed getting up from my seat on the towels.

It was around 6 pm now and the sun was already setting. "And then after we can head home."

"Yeah I'd love that actually."  We strolled alongside the beach that waved back and forth to our feet in search of seashells.

"Look how many there is over here." I squatted down to where the golden spot was and grazed my fingers through them all. "They're so pretty," I said looking back at Mikasa who was staring at me intently. "Yeah I didn't realize how gorgeous seashells were." I grabbed as many  as I could and collected them in the front packet of my bag.

From the corner of my eye I spotted one isolated. It was the perfect size not too small and not too big where it would look tacky on a piece of jewelry. I picked it up and it had a familiar aura to it. It had the same Aura as Mikasa I don't know how else to explain it it just radiated her spirit. The colors from the sunset made it pop out more. "This. This ones the one."

"I think this one looks better," Mikasa responded handing me another one she found. I put them both in my bag and zipped it shut finally. "I think I have more than enough now."

-

"Sunscreen check, towels check, chairs check, umbrella check, change of clothes check, deodorant check, cooler check, everything else check-"

"You are such a control freak," Mikasa cut me off wrapping her arms around me from behind as I searched around for anything we were missing. "That's mean,"

"In the hottest way possible," she corrected bringing her lips down to kiss my cheek. "I just like to be organized and planned," I argued back. Turning to her to make sure she was dressed already. "Good you're dressed."

"You're not even dressed yourself," she commented back. "Yeah I'm going to right now, can you start filling the cooler with ice now, we leave in 5 minutes?"

"Sure." She walked out the room and closed the door as I started to slip into my red bikini. I heard the ice being poured right as I finished tying the string around my neck facing the mirror.

As if on cue, Mikasa walked back into the room to notify me she was done.  "Alright, I'm ready now," I said as Mikasa walked up to me and ran her fingers up my thighs. "I'm not."

"Not this time, we have to goooo,"I said trying to not break.

She slowly untied the top and watched the string fall to my sides revealing me.  She stroked lightly against the bikini bottom fabric in a teasing matter. "So you're telling me you don't want me to touch you?"

"Uhhh-" she dragged her lips against my earlobe and used her other hand to hold my throat making me shiver. "Okay, I guess we can wait five minutes," I gave in.

She fucked my ear with her tongue leaving a cold indescribable sensation while rubbing on my clit against the fabric.

Mikasa tugged me down at the bed where I was displayed before her laying flat down. Her wet tongue coated in salivate as it trailed down my body slowly in a torturing way. She started from throat and neck to my collarbones. She savored the taste of my skin in her mouth taking her time to devour me. Her tongue led down to my chest where she slowly licked around in circles till she reached my nipples and continued the slow circle motion. The sensitive sensation caused me to feel over stimulated and I couldn't catch my breath as she started to pick up her speed and go in fast circular motions now. She dragged her tongue from one to the other without ever pulling away her tongue she did the same slobbering to the other. My chest was all wet by her saliva and spit. Each time she went back to the other one she used her tongue to follow the path. Her tongue crossed  like there was a bridge way between the two.

This feeling alone was about to make me orgasm before she stopped right before my climax causing everything to feel more sensitive now as I just got edged.

Her tongue was now trailing from the space between my chest to down my stomach in a line. Her tongue slid down perfectly smooth as if water was dripping down my torso.

Her tongue exploration youthful and playful and my whole body felt like it was vibrating in sensation. Mikasa pulled my bikini bottoms down to my thighs and let out a small smile at how wet she made me. Being able to make her proud turned me on even more because my life purpose was to devoted to being her little sex doll she could do whatever she wanted to. I wanted to be treated as nothing more than her property. Whether that meant I would walk around in a uniform serve her like my master or let her use my body at any time of the day she wanted to.

She flicked my clit around with her long tongue  up and down then side to side. Then she started to pull her fingers out to give her assistance. She used two to start off with pleasuring rubs. Her tongue worked in sync on my clit as it did with her fingers in the lower area. I didn't want to wait anymore for her fingers to penetrate me. She started to quicken her pace and create longer licks with her tongue while her two fingers started to slip into me absolutely fucking me with them. My head felt so hot as everything was getting so fast and rough. My breathing was heavy and her speed made my noises louder.

I was able to see her fingers come in and out of me wetly coated each time. At this point the full length of her fingers were going in and out. Each time she released I awaited for her upcoming entrance. I didn't know how to focus on a sensation. It felt like all my senses were clogged. Like if every hole in my body was filled with stuffing.  I could feel her tongue and fingers all at once. She spit down at my clit and used that saliva to coat it all over my clit again.

There wasn't a point where she slowed down, she just kept going faster and faster until my I started to throb and coat her fingers with something new. Once she saw I was satisfied she pulled her fingers away and licked them slowly from the bottom to the top in front of me. She cleaned the rest of the mess on me with her tongue before pulling my bottoms back up.

"I believe 5 minutes have passed."
