My Sister the Christmas Cruise Slut

I was still at a loss for what to do. I tried to hide my confusion by pulling Holly into another kiss. Maybe something would come to me while we kissed. Instead, an idea occurred to her. While we kissed, I felt her tiny fingers working the front of my shorts. She deftly undid the top button and slipped her hand inside, forcing the zipper open as her hand slid inside my boxers, too. I felt my shorts and underwear sliding down my legs and froze when Holly caressed my exposed cock.

"Let's move inside," Sean suggested though no one could see us. "The furniture is more comfortable." I scooped up my shorts and boxers, holding them over my hard cock. Sean gestured for us to sit on the couch. I sat on one end and Holly sat right next to me. She pulled away my shorts, forcing me to keep my cock on display.

"Damn, your big," Lisa purred, openly staring between my legs. "I can't wait to have that."

"Easy baby," Sean said, patting her knee as they sat in the two chairs facing the couch. They scooted the chairs close together and kissed. During that kiss, Lisa worked off Sean's shorts, exposing him, too. Sean had reasons to be proud down there, too. As they kissed, Lisa tugged and pulled on his big cock with eager enthusiasm. They finally pulled away and smiled at us.

"Oh wait, we're supposed to do something more," Lisa said, standing. She pulled off her bottoms, both her shorts and panties and exposing a second set of tanlines. This set included two thin lines that disappeared around her narrow waist and tiny swatch of white that barely covered pussy. I couldn't help but wonder how she looked in whatever bikini she wore while tanning. Based on her tanlines, it was lowest cut bikini bottom possible. Like Holly, Lisa was shaved. Unlike Holly, Lisa had kept a tiny swatch of light brown pubic hair right above her slit.

"You are so beautiful," Holly gushed, openly staring at the other woman.

"Thanks. Sean likes tan lines."

"I like all over tans, too," he quicking added, looking at my sister.

"Holly has an all over tan," I volunteered. "Why don't you show it to them, baby?"

"Why don't you show it to them for me?" she asked, grinning. I knew what she wanted. She wanted me to undress her. My fingers shook as I pulled off her top, exposing her braless tits. Lisa and Sean both cooed their appreciation of her big tits. I knelt in front of Holly and pulled off her shorts and panties, giving me a solid look between her legs. I averted my eyes, looking at her thigh instead of her pussy. While I was still between her legs, she tugged at my shirt, pulling it off my head so I was naked, too.

I moved back to the couch, embarrassed and nervous feeling. It felt awkward being naked and hard in front of two strangers and my sister. Sitting next to Holly made it feel worse. I focused on Lisa and her beautiful body. She was easy to admire and her eager stare held promises of what might happen next.

"Could you stroke him for me?" Lisa asked Holly, meaning: could Holly stroke me. I felt my heart pounding in my chest as Holly wrapped her tiny hand around my big cock and caressed me as if I was her lover. "Mm, that looks so sexy," Lisa purred, slipping off her chair and kneeling in front of me. She caressed my knees and thighs as she watched Holly's hand. "His cock is so fucking big. How much of it can you fit in your mouth?"

"Most of it," Holly lied.

"Show me," Lisa cooed. "I want to see."

I squirmed, panicked as I desperately tried to find a way to stop it from happening, except what could I do? Holly was kneeling in front of me, caressing my legs and blocking any escape path I might have. My choices were plain. Either I push the pretty blonde away, snatch my clothes and run away or I sat there and endured whatever happened next. I looked at Holly, hoping against hope she had a plan for avoiding Lisa's request.

"It's okay if you want to do it for me," Holly said.

"No, I want to see you do it," Lisa insisted. "Is that okay?" She gave us both a worried look.

"Sure it is," Holly said, bending over. "Why wouldn't it be?"

Because you're my sister! I wanted to scream, except I didn't. I bit my tongue and braced myself for something I never wanted. I stared down, mostly looking at Lisa, but seeing the back of Holly's head as she moved into position. A moment later, I felt a tentative lick before she opened her mouth and drew my hard cock between her lips. I released a low, mournful moan as another permanent line was forever crossed.

"Hey, it's okay," Lisa purred, reaching over my sister and caressing my cheek. "Relax and enjoy."

I can't imagine how terrified I must have looked sitting there with my cock inside my sister's mouth, but what could I do about it? Making matters worse? It felt damn good. Holly knew how to suck cock and wasn't holding back. Nothing about the way her tongue licked, lapped, circled and teased my cock suggested she was holding back. Holly was going for it as if it didn't matter.

"It's only Holly touching you," Lisa said, offering a comforting smile. Of course, she had no idea she had just named the exact reason why I was freaking out. What was wrong with my sister? Why wasn't she trying to change the direction of things? Did she feel as trapped as me? A long, mournful groan escaped my lips.

"Sounds as if someone has been waiting for this," Sean chuckled, getting it as wrong as his girlfriend.

"Do it," Lisa purred, caressing my sister's back. "Suck it. Suck that big, fat cock. You know you want it. You know you love it."

Holly moaned. I don't know why. Was she moaning because she knew she was doing this to me or because she actually liked it?

"That's it," Lisa said, pushing down on Holly's head. "Take it. Take it all. Let him choke you." I heard Holly gag and keep going. "Yeah, do it. Gag on it. Gag on that big cock," Lisa insisted, forcing Holly to gag again.

"Okay, you need to stop that," Holly snapped, pulling away. "I don't mind sucking him, but I don't like to gag."

"Sorry," Lisa said, pulling away. "Just trying to have some fun."

"No, it's okay," Holly quickly said. "Here, you do it."

"Can I?" Lisa asked, looking over her shoulder at Sean.

"Maybe tomorrow," he said.

"But baby, he's so big!"

"I know and he'll be big tomorrow, too."

"Wait," Holly interjected. "Is this all we're going to do tonight?"

"We don't swap on the first night," Lisa said as if that explained anything. Holly gave me a confused look. I shrugged because I didn't understand either.

"Just a little rule of ours," Sean said, pulling Lisa to him. He started groping her chest while Lisa snuggled close to him. "We hate one night stands, so the first time we're with a new couple, we just like to do it in the same room."

"Do what?" I asked.

"Whatever you're comfortable doing," Lisa said, slipping her hand between Sean's legs and caressing his hard cock. "Would you like to see me suck him?" She bent over, taking Sean's prick inside her mouth while keeping her eyes open and on us.

"Doesn't she look good doing that?" Sean asked me. "She loves sucking cock. Just wait until tomorrow when she does it to you."

"But not tonight?" Holly asked.

Sean said, looking worried. "We like to take things slow."

I looked at Holly for an explanation. She looked puzzled but looked as if she was putting the pieces together. "Oh, so that's what you meant when you said you liked to watch and show-off?"

Lisa popped his cock from her mouth long enough to add, "Mm, I love being watched. It gets me so wet." She snaked a hand between her legs as she went back to sucking on her man.

"What are we supposed to do?" I asked.

"Whatever you want," Sean said.

"Do we have to do anything?" I asked.

"It's better if you do," Sean said with a patient look on his face. "But, if you're okay with it, we'll keep going."

"Good, because I want this," Lisa said, pulling away. She sat up and kissed Sean while Holly and I gaped at them. Slowly, we looked at each other.

"Should I suck you some more?" Holly asked. My wide-eyed look was the only answer she needed. Still, it felt awkward not doing anything while we watched Lisa sucking Sean. Holly cuddled closer and started stroking me. That felt like a good compromise. In fact, it felt like a good compromise and I relaxed. "Doesn't she look sexy doing that?"

Lisa's eyes lit up hearing Holly's compliment. "Beautiful," I agreed. Sean moaned. Apparently our compliments improved Lisa's technique.

"I can't wait to suck his cock," Holly added. "I want to feel him deep down my throat." I moaned, too. Hearing Holly talking dirty was getting to me. My cock swelled in her hand as I relaxed into the moment. "Mm, you like that idea?" she purred, noticing the change. "You like the idea of seeing my lips wrapped around Sean's big, hard cock?"

"Yes," I quietly whispered, ashamed that I could get so excited thinking about my sister sucking Sean's cock. I squirmed, wanting more and terrified because, well, because I wanted more. I draped my arm around her shoulder and grabbed at one of her big tits. Damn Holly had great tits.

"Let me suck you again," she whispered in my ear, too soft for Sean or Lisa to hear.

"No," I whispered back, knowing that if she hadn't asked, I wouldn't have stopped her.

"I want this," she said, loud enough for everyone to hear. She kissed me and I kissed her back. Our kiss didn't last long because we didn't want to miss the show happening just a couple feet away. She pulled my arm over her head. "At least touch me, too." She pushed my hand between her legs and my fingers slipped against her pussy.

Holly parted her legs wider, opening them towards Sean so he could see my fingers as I rubbed her pussy. My fingers slipped inside and around her pussy, caressing her clit and feeling inside of her. She was hot, wet, and slippery. We both moaned.

"That looks good enough to eat," Sean grinned, staring between her legs.

Lisa pulled away from Sean's cock and watched up for a second before she said, "Do it. Eat her for me."

"Yeah," Holly said, smirking at me. "I went down on you. You should go down on me, too." She pulled away, moving to the other side of the couch with one leg on the floor and while bending her other knee, opening her pussy to me. "Do it," she said. "Eat me. I dare you."

I watched as she rubbed her pussy, waiting for me to make up my mind. I looked at Lisa who smiled her encouragement. "I've never done it with an audience," I said, as if that might explain my reluctance.

"Just do it," Lisa urged and with a hot, fiery look in her pretty blue eyes.

I felt trapped by circumstance. Everyone in the room was waiting for me to do it. I stared at Lisa's eager look most of all and slipped off the couch. I knelt on the floor and I kissed Holly's inner thigh several times as I built up the courage to keep going. Maybe I could pretend I was doing it?

As I neared her pussy, I could smell Holly's excitement. I know I'm talking about my sister, but what can I say? I was already hard as hell and throbbing with excitement. My head buzzed with confusion, shame, excitement, and desire. I love eating pussy, I always have. I love the taste, aroma, and intimacy of pressing my face against a woman's pussy. I've always felt as if eating pussy was an art form. A woman's clit the most sensitive part of her body. Figure out how to treat that little nub just right and she's yours for life.

I kissed up her thigh and across her pussy, deeply inhaling my sister's scent. It was too much for me. I couldn't resist and knew I couldn't simulate giving her head. I gave into the moment, pressing my face against Holly's bald, smooth pussy and shoving my tongue between her nether lips.

The moment I tasted her, it no longer matter if she was my sister or not. It didn't matter. Her pussy tasted wonderful. I moaned loudly and went for it, licking and lapping at the tiny nub of her clitoris and hearing her gasp. I smiled, at least on the inside I did. Take it, bitch, your brother knows what he's doing when he's between a woman's legs!

I snaked a hand beneath my chin and pushed two fingers inside Holly, ignoring that I was fingerfucking my sister. It didn't matter anymore. I had a single goal in mind and I wouldn't stop until she came. If Holly wanted this, I would give it to her. My tongue circled her clit as I lapped up the flood of her excitement. Hearing her moan and feeling her fingers lost in my hair only encouraged me.

"Fuck, he's good," I heard Lisa say. Damn right. Give me a chance and I'll eat a woman into an orgasmic coma.

Holly moaned. It started as a low growl and kept building. "Yes," she cried out as she moved closer to her orgasm. "Yes!" she cried louder. I wasn't going to back away. I wasn't done until I felt her quiver and I knew I was close. "YES!" she called out right before bucking beneath me as the orgasm I gave my sister rocked her world. By the time I pulled away, my face was covered in her juices and she looked crazed with pleasure.

"Holy fuck," she groaned, staring at me with respect in her eyes.

"Damn," Sean agreed. I glanced in their direction and saw them both staring. I moved back to my couch, no longer caring who saw my hard cock between legs.

"Look how hard he is," Lisa said. She was right because eating pussy always gets to me. My cock was harder and felt more needy than ever before.

"I want this," Holly said, grabbing at my hard cock.

I don't know where I found the strength to resist, but I did, "No."

"Please?" she begged.

"Would it help if we do it, too?" Lisa asked, rubbing Sean's hard cock.

I shook my head. Holly and I had gone far enough. No way was I going to fuck my sister.

"Please fuck me," Holly begged again.

"Not tonight," I said with a level gaze at Sean and Lisa. They wanted to draw line between us? Fine, I'd draw a line, too.

"I like that," Sean said. "A man with self-control."

"You know it," I agreed.

"Are you going to save yourself for tomorrow?" he asked.

"At least until we get back to our room," I said, reaching for my clothes. Fuck this. I didn't come here to have sex with my sister. I came here hoping to have sex with Lisa. If that wasn't going to happen tonight, then why stay? They had gotten their show. Of course, I knew I wasn't going to fuck Holly when we got back to the room. But I would jerk off. I had to. I was too damn excited.

"Bastard," Holly groaned.

"Men are such jerks," Lisa said, gracefully swinging a leg across Sean's lap until she was straddling him. She lowered herself directly over his hard cock without using her hands That's when Sean put his hand around her waist and locked her into place.

"Maybe we should wait, too," he said, lifting her off of him.

"You don't want an orgasm?" Lisa asked, sounding shocked.

"Of course I do," he grinned. "But if he can wait, so can I."

"You're right," Lisa pouted, looking at Holly. "He is a bastard."

Holly giggled. Meanwhile, Sean stood snagged his shorts and pulled them back on. Slowly, the four of us got dressed.

"Tomorrow?" Sean asked Holly before we left.

"Tomorrow," Holly promised. She kissed Sean and I kissed Lisa.

The pretty blonde grabbed at my cock while we kissed. "Tomorrow," she said.

I had to hold my hands over my cock as we walked back to our room. I knew my cock would stay hard until I gave it some relief. "Damn, you're good," Holly said as we walked and I knew my pussy eating skills had cursed me. Every woman I had ever met loved how I did it.

"Shut up," I growled, not wanting to talk about what had happened. We rode the elevator in silence and wasn't until we were walking down our passageway that I couldn't stand it anymore. "I can't believe you went down on me."

"What was I supposed to do?"

"I don't know," I grumbled, working the key to our room.

"I'm serious, we had to do something. You were there. You saw how it went."

"I know," I said, holding open the door to our miniature stateroom. It wasn't her fault I was on edge. I felt needy as hell. My cock ached. Hell, even my balls ached. I felt as if I had just spent the last two hours with a prick tease.

"Do you want to do something?" Holly asked, sitting on her bed.

"Yeah, I'm going to jerk off," I said, turning the TV and searching for more late night soft porn, anything I could use for inspiration that might take my mind away from what my sister and I had just done. I turned off the bedside lamp and laid on my bed, caressing the lump inside shorts. The TV light up the room more than I liked, but did it matter? Holly had already seen me naked and then some.

I looked over and saw her watching the TV with one hand inside her panties. Women have it easy. They can just stick their hand inside their pants whenever they want to get off. My aching cock throbbed. Was it because of what Holly was doing? I didn't know and didn't care. I needed to get off. I pulled off my shorts and caught Holly looking. "Keep your eyes on the TV," I said.

"Let me help you," she said, sitting up on her bed.

"No," I said, determined to ignore her. I kept my eyes on the TV and caressed my cock, hoping i could get off quickly, ease the tension and go to sleep.

"Please," she said, kneeling next to my bed. She slipped her tiny hand over my big cock. "I owe you."

"Don't," I said, but I didn't stop her. I didn't push her hand away because it felt too good.

"Tell me to stop and I will," she said, still stroking me.

I wanted to say the words, I really did. Except her hand felt better than mine. Besides, did it really matter? I kept my eyes on the TV, allowed her to keep going, and everything was fine until she leaned over and drew my hard cock back between her lips. "What are you doing?" I said, staring down at the back of her head in shock.

"Paying you back," she said, flashing me a smile before going back to work.

I sighed as I wrestled with my conscious. This was wrong, so very, very wrong. When we were with Lisa and Sean, we sort of had to do stuff, didn't we? Doing stuff in front of Lisa and Sean helped prove we were a couple instead of brother and sister. But now we were alone. Now, there wasn't a reason for Holly sucking my cock unless she really wanted to do it.

I opened my mouth, trying to tell her to stop, and only released a mournful groan. Like when we were upstairs with Lisa and Sean, I felt helpless, trapped by circumstance. Every moral fiber I had screamed she should stop. That same conscious told me I was complicit if I didn't make her stop. Except, I wasn't forcing her to do it. I hadn't asked her to do it. She didn't have to do it if she didn't want to do it. She didn't really owe me. And, perhaps worst of all, it felt good. Damn good.

Unwilling to make her stop, I gave into what she was doing. I pushed past my guilt and shame and accepted the pleasurable sensations Holly offered. Her felt warm and her tongue felt wet. I heard and felt a soft moan from her. Fuck it. I gave in. I stopped fighting and allowed nature and my most animalistic needs to take over.

Holly tugged and pulled on my big, fat dick. She used both hands, one for caressing my swollen, needful balls and the other hand for stroking me. She swirled her tongue around my cockhead, delighting me in ways other women hadn't done for me. I gasped, arched my back, and warned her, "I'm gonna cum!"

Instead of backing away, Holly doubled her efforts on my hot cock. She sucked me faster and tugged on me with greater insistence. She squeezed my balls, tempting and teasing me to release my orgasm and I did. I came. I came deep and hard inside her mouth, releasing a huge amount of spunk as my orgasm began. All my sexual frustrations left me, filling her mouth as semen.

Holly groaned and kept her lips wrapped around my dick. My orgasm was over, but she kept sucking me. "Hey, I'm good," I softly told her, caressing the side of her face.
