*****

I awoke the next morning to someone knocking on the door.

"Come in," Nate said cheerily as he opened it. As soon as I heard his voice my eyes shot open, and I remembered everything that had happened the night before.

No! my mind screamed. What is he thinking?!

When I tried to go back to my own bed, I saw that I was already there...and I wasn't naked!

"Morning, you two!" my dad announced happily. I looked up toward them, still groggy and confused. Nate came over and stood by my side. Once everyone was inside I looked to him for help.

"Anya did something to her back last night," Nate explained. When I tried to sit up, I didn't have to fake the soreness.

Damn! I thought to myself. I knew your first time could leave you a little sore. But I didn't think it would actually be this bad. Jesus! The pain was terrible.

"Oh, honey! What happened?" my mom asked.

"I fell in the bathroom," I made up, looking at Nate. He had a hint of a greedy smile on his face.

"I'll opt out of pool time today to take care of her," Nate offered.

"Are you sure?" My dad asked. "One of us can stay back too."

"Nah, it's fine. I snuck out to the bar and had just a bit too much tequila last night anyway," he lied. "Kind of feeling it."

"Okay, then. If you're sure..." Nate nodded.

"We'll be back in a few hours to check on you guys" said my mom.

"No need to worry about me," I replied. "Go have fun. We might catch up with you later." She looked at me uncertainly.

.

"Are you sure?" she asked. I nodded.

"Yeah. I'll be okay," I answered. "Nate will let you know if we need anything." When they looked to him he nodded. They seemed to be satisfied with that. Well, my dad did anyway. My mom looked away.

She wouldn't know. Right? I asked myself. No, she's just worried.

'

"Okay, then...we'll see you later." She tried to smile and kissed my forehead before leaving with my dad.

Margret and Wayne

Wayne hooked his arm around his wife's waist, still reveling in the accomplishment and all of the sex from the night before. He was glad the hotel had good soundproofing. Marge was a little less happy. When he finally took note of her concerned expression, he stopped walking and turned her toward him.

"What is it?" he asked. She looked at him, an expression of uncertainty on her face..

"I don't know" she replied."Don't you think something seemed a little...off with them?" He gave her a questioning look. She shrugged. "I don't know. You don't think they're fighting do you? They didn't seem like they..."

"I think," Wayne interrupted her, "they were under the bed Rosalind and some guy were bouncing last night. And you think they were acting more strangely than usual? Maybe it ignited a spark and they had a little fun." He shook his head. "Well yeah, that's what they usually do. At their age, we probably would have too."

"And now they're staying in the hotel room together... because she hurt her back?" she countered with her true worries.

"I'm not getting it." He shook his head again. She rolled her eyes.

"She was hurting. Anyone could see that. But it didn't look like it was her back." She was trying to imply there was something more. He still wasn't understanding where she was headed. She sighed.

"Never mind. You're right. I'm overreacting to things," she lied before continuing on her way.

But if they're having sex thinking they're brother and sister...Marge thought.

Nate

I carefully got into bed beside her.

"You feeling okay?" I asked softly.

Seeing how much she had enjoyed being taken so roughly I had forgotten she still had no experience with sex before last night. I expected her to play along with my little scenario, but I saw it when she sat up. She really was sore.

"Just fine!" she spat, the sarcasm cutting her words like a sharp knife. "I could have done without the heart attack too." She glared at me. I laughed.

"I'm sorry. I would have woke you but you looked so peaceful," I lied. As soon as she closed her eyes and carefully leaned into me I couldn't help but look at the nightstand where I had put my sketchbook.

When we had gone to bed last night, I knew I would probably wake today before she did. And as I suspected I only needed to nap a couple hours before I was refreshed enough to take care of making sure we weren't going to be seen in a compromising situation. When I carried her back to her own bed she stirred a little. After I got her dressed in a nightie, she snuggled into the blankets. I don't think she even realized I had moved her.

There was a full moon out and her bed was next to a window. I opened the drapes to let the light shine onto her. She looked so mesmerizing lying there in the dim light I couldn't help myself. I began to sketch her, wanting to get every detail perfect; her eyes, the little bit of wetness still clinging in the corners from the painful pleasure I had given her; her mouth slightly parted, but not quite enough to leave much of a gap between her soft lips; her hair...

By the time I was done it was morning. I tried to sleep a little, but knew it wouldn't be long before Mom and Dad knocked on the door. So I got dressed and was ready to lie my ass off.

My present train of thought was interrupted when I felt her lips on my chest.

"I know it's selfish for me to ask..." she hesitated briefly. "...but I really would like a bath," she mewed, looking up at me, her blue eyes pleading.

"Not at all. Need some help?" I asked. She blushed slightly.

"Maybe," she teased. "But only with the bath; nothing more." I chuckled and kissed her forehead before carefully helping her to her feet.

"Ow!" She looked surprised. I watched her, waiting to see if she was going to be able to gain her balance. "I thought people were only joking when they said they couldn't walk after their first time." She held onto my shoulder before taking her first few steps.

I felt a little guilty - but only a little. Seeing her walking so slowly because of what I had done to her made me hard. As much as I wanted only to be support to her today, I couldn't get last night out of my mind. I wanted her again. .

"I was a little rough," I said with a chuckle. She looked up at me.

"You can wipe that silly little grin off of your face." She mocked, then chuckled. I kissed her, a quick peck on the cheek.

"Actually I don't think I can," I retorted. And I was serious. I could think of nothing but being with her again. I was smiling, remembering how it felt to be between her legs, to be inside her. I wanted that feeling again and again. But it would have to wait.

After we had made it to the bathroom she stood up and leaned against the vanity while I got the tub ready for her. When I turned the water off she tried to step into the tub.

"What?" she asked. I had placed my hands on her hips, restraining her gently.

"It's probably going to be a little difficult for you to get in, being so sore. And when you sit down..." I chuckled.

"I was just going to step in," she said sternly. "I haven't taken my nightie off yet." I let go of her. As soon as she tried again, she winced.

"Okay, you're right," she said softly. "Help?" She asked, chuckling. I had her sit on the edge of the tub and placed my hand behind her calf. Lifting gently, I eased her leg over the edge of the tub wall, slowly as she winced in pain. I couldn't help but peek at the view this offered. I looked directly into that treasured area that was presently causing her so much difficulty. After we had positioned one foot in the tub, I did the same with her other leg. I then began removing her nightie. She looked up at me.

"Don't forget I've already seen you totally naked," I smiled. "No need to be shy now." I removed her garment with no resistance from her.

"What would Mom and Dad have said if they had noticed I didn't have any panties on?" she asked. I chuckled.

"I made sure you were covered before I opened the door," I replied.

She placed her hands on the sides of the tub. I reached under her armpits and helped her slowly settle into the warm water.

"You good?" I asked. She nodded. I seated myself on the toilet so I'd be close by if she needed anything. Actually, I was taking pleasure in seeing her naked body. She was so beautiful I just wanted to look at her for a moment. My cock was still throbbing. I wanted so badly to feel her warmth surround me.

"I'm kind of enjoying this, actually," she admitted with a blush.

"What? The painful ache between your thighs?" I asked with a chuckle. She laughed.

"No, you ass wipe. Definitely not that! I meant you taking care of me," she admitted. I raised my eyebrow.

She's not exactly the kind to ask for help, I thought to myself.

"You are?" I asked. She nodded...and with that I got an idea.

She watched me stand up and begin taking my clothes off. Her eyes widened when she saw my pulsing cock..

"Uh...not that I'm complaining, but I don't think I'm qui-"

"No worries," I interrupted her. "I don't plan on using it...yet. Move forward." Not sure if she should trust me, she warily did as I asked. I picked up one of the plastic cups they always have in hotel rooms, then I carefully got into the tub behind her. It was a fairly big bath, so I could move freely with her. I sat, my legs open and her nestled between them. She watched over her shoulder as I positioned myself. My cock lay against her back.

"Hand me that?" I asked, pointing to the little shampoo and conditioner bottles in front of her.

She turned her head, looking back at me, a little surprised. I chuckled.

"Come on, pass it over." She handed them to me while bracing herself.

I placed the bottles beside me then reached down with the cup, filling it with water. I slowly poured it over her hair. She leaned back toward me, enjoying the feel of the water flowing through her hair and over her shoulders. Once totally wet I squeezed some of the shampoo onto her hair and started massaging it in. She let out a sigh and I felt her relax even more. She leaned back against me. My cock twitched, wanting to be back inside her. She chuckled.

"Down boy!" she giggled. I smiled and kept massaging her head with the shampoo until the lather had penetrated every inch of her hair. Then It was time to rinse and move on to the conditioner.

"Close your eyes," I whispered into her ear. She closed them and let the water clean the shampoo from her hair.

When the sweet smelling conditioner was settled into her hair I let my hands travel to her neck and shoulders, rubbing her more as she went limp into me.

"You're spoiling me," she breathed. I gently pulled her head back more and kissed her forehead.

"I want to spoil you," I admitted. When she was relaxed I let one hand travel down to her breast and started toying with her nipple. She stiffened and gasped a little, opening her eyes.

"Sh-h. Just relax, baby girl," I coaxed. She tried, but her nipples were so sensitive she moaned under my manipulation. I tweaked each nipple for a few moments.

After I'd had my fun I slowed down, rubbing her areola, not wanting to get her too excited while she was so sore. She turned a little and started kissing my chest.

"Rinse it out?" she breathed looking up at me. I raised an eyebrow before doing as she asked.

"Help me up?" she asked when I had thoroughly rinsed the conditioner from her hair. I was more than a little disappointed, but did as she asked.

When we were both dried she took my hand, trying to lead me into the main room. She winced in pain, so I led as she followed.

"Put more pillows at the head of the bed," she instructed once we were beside the bed. I had expected she would want to don a clean gown and lie down.

"O-o-okay...?" I replied questioningly. She watched me rearrange them for her. When I had done as she asked I positioned myself to help her lie down. She just looked at me with a mischievous smile on her lips.

"Lay down," she laughed.

What is she doing? I asked myself.

I did as she asked. Then she carefully lay down, rolling over next to and partially laying on top of me.

"Whoa! You're not ready..." I began. She placed a finger across my lips, quieting my protest.

"I'm not," she interrupted, looking at me. I looked at her, confused for a moment before she smiled and kissed me. Not a long passionate kiss, but a soft, gentle, loving kiss. Her tender lips felt so good against my own.

We parted and, as she got ready to inch lower, it dawned on me what she was doing. My cock, which had gone limp, sprang up once again.

"You sure?" I asked excitedly. She chuckled and started kissing down my body, soft little kisses that left tiny wet spots on my chest and stomach, inching toward my cock. My stomach was going crazy with the excitement. I wanted her to do it so badly...and then she slowly touched her tongue to the head. My cock lurched and I moaned, pressing my head back into the pillows. As soon as I did this, she slipped the entire length of my cock into her mouth.

"Holy fuck, Anya!" I groaned.I looked down at her to see the concentration in her eyes while she gazed back into mine. Normally I'd guide girls on how hard to suck, how fast to go. But she did exactly what I wanted without me saying anything at all. She deep throat-ed me a few times, but focused mainly on my balls and the head, working the top of my shaft while licking my sac; teasing the head with her tongue while rubbing my balls and stroking me; letting me see the outline of my cock pressed into the inside of her cheek. I couldn't help myself. I was ready to cum within minutes.

She saw that I was close and pulled back. She wrapped her tits around my cock, bouncing them up and down while flicking the head with her tongue. Sensing I was about to erupt, she took me back deep inside her throat, bobbing up and down, intent on sucking every drop of cum from my balls as I exploded. I was left groaning and seeing stars...literally seeing fucking stars.

"Jesus Christ, Anya!" I breathed. She laid back down beside me and I could see that she had swallowed every drop of my cum. "Fuck!" I closed my eyes, laying back into the pillows.

"You take care of me, I take care of you," she smiled.

"Come here," I breathed, pulling her closer. I began kissing her deeply, showing her my appreciation. When we paused for breath she nestled into my chest.

"Need a nap?" she asked. I nodded.

"Usually I'm more pumped after sex or a blow-job. But holy fuck, baby girl! You're way too damn good at that. You sucked it right out of me!" I looked at her. She was beaming, proud of herself in that she had so thoroughly satisfied me. I chuckled. "You're really cute right now," I admitted. She blushed, trying to turn over. But I held her close. "Cuddle with me?" I asked rather than stated. With rosy red cheeks, she pressed her head into my neck and let me hold her. Suddenly my eyes became very heavy, and I was starting to drift off to sleep.

****

I awoke and noticed a note beside my face. I sat up with a yawn and read it.

"Off to the pool with Mom and Dad. I found a bit of a solution for the soreness, plus the water of the pool should help. You seemed as if you needed some rest, so I left you sleeping. See you later. Love you." She left a purposeful kiss, marked with red lipstick at the end.

We had said it nonchalantly millions of times before. But this...this "Love you" was different. It had a whole new meaning to it now. I stared at it for some time. "Love you."

I love you too, baby sister, I thought to myself.

I couldn't just throw it away. Not this piece of her that was so freely given. With a smile on my face I opened the drawer in the nightstand and placed the note alongside the new drawing of her. I knew this was one trip I was going to remember for the rest of my life.

****

I came around the corner of the hotel with a smile on my face. My mom waved me over and patted the spot beside her.

"Mother." I let her hug me.

"Your sister seems to be doing a little better," Mom said. "Although she's also had a few Margaritas." Dad laughed.

"How many is it she's had?" he asked while putting sunglasses on. My mom laughed.

"At least five," she replied. I smiled, looking for An in the pool. I spied her out in the middle lying on a plastic flotation device. She was one of only a few in this section of the pool, so she wasn't hard to locate. She was wearing a deep blue bikini that offset her tanned skin.

"I'll go see how she's doing." I got up and slowly made my way into the water. Right then I knew why people were sticking to sunning. It was fucking cold!

I slowly and quietly made my way to her. She was floating toward the corner of the "L" shaped pool, which wrapped around the side of the hotel. When I reached her I moved ever so slowly, pushing her further around the corner. Our parents wouldn't be able to see us here. I gently grasped her shoulders and kissed her. Her eyes shot open, startled for a moment, but then kissed me back after seeing who it was. Suddenly she pushed me away.

"What if Mom and Dad see us?!" she gasped.

"Relax, little girl," I replied, nodding my head in the direction they would be. "They can't see us here. It's safe." Seeing our location, she kissed me again, more deeply this time. My cock began to stir. I pulled away from her.

"So what was your solution?" I asked out of curiosity. She smiled.

"I'm not sure you want to know," she giggled.

"What?" I asked with a chuckle.

"Ice.." Her eyes sparkled as she saw my mouth drop wide open.

She shoved ice inside herself?! I thought.

I stared at her, partially in fascination because I was turned on by it.

"You...put ice...inside your...?" I stuttered. She giggled.

"No, silly. I just rubbed it around some. It made the whole area kind of numb after a while and eased the pain. The alcohol in the Margaritas helped too." She giggled again.

Fuck, that's not helping, I thought. At this rate I was going to walk out of the pool with a raging hard on!

"You're poking my shoulder." She laughed. I looked down. The water wasn't even waist-deep by the edge of the pool, and I saw my cock digging right into her shoulder, close to her neck.

Shit! I need to take care of that.

She looked up at me, then suddenly rolled off the device and stood. Taking my hand she led me further from the wall (to conceal my situation) and over to the swim-up bar. There was a live band playing in front of us and we were in the midst of a small crowd of people.

"Get right behind me. People won't see," she whispered into my ear before turning around and positioning herself directly in front of me. I moved forward, pressing my stiff cock into her lower back.

"See what?" In answer I felt her hand reach inside my trunks and wrap around my erection. I immediately adjusted myself, looking around to be sure no one was in position to see what was happening. Everyone was intently watching and listening to the band.

With our proximity to each other, she couldn't stroke me all that well. But it was fucking hot none-the-less!

.

"Think back to my mouth on you," she whispered back at me.

Fuck! How could I think of anything else?

I held onto her waist tightly, kissing her neck, trying not to moan. More people moved in, surrounding us as everyone watched the show. None of them noticed us. To them we were just another couple close together, swaying to the music, enjoying the show. All I had to hope for was that our parents weren't going to come in. The risk of being caught drove me wild.

"Expose my ass," she sighed while I kept kissing her neck. I reached down and pulled the bottom of her bikini aside, being sure it stayed attached at her waist, exposing her ass in all its round glory. I couldn't help myself. An almost automated response was to pull my cock from her hand and place it between those luscious cheeks. I wasn't in her ass, but between her cheeks was enough. I bit her neck, trying not to moan as we kept swaying to the music. It was incredible! No one cared. No one saw us. If they did, they weren't saying or doing anything about it.
