A Week at the Lake with My Sister (Old)

By the time I reached the bra strap, I could smell Kaitlyn's excitement. It made me realize how far over the line was what I had done. I stopped immediately and looked across the room. Joanna had a smile on her face and seemed to be laughing lightly. Paul was holding her lightly and seemed to be talking to her instead of trying to learn what I was doing.

Kaitlyn shot up out of the chair and said loudly to Paul, "Let's go to our bedroom. Now." She held out her hand for Paul. Paul gave her an eager smile as he quickly crossed the room to her. They walked into their bedroom and slammed the door.

I saw movement and turned to see Joanna throw a towel over the couch. The bra was gone, and she quickly slipped off her panties. She lay down on the couch and said, "Eat me, Brandon."

I lay chest-down on the couch in front of Joanna as she spread her legs wide. I worked my tongue up and down her slit, getting her warmed up. Then I heard the first "Oh!" from Kaitlyn. Joanna put her hands on the side of my head and said, "Keep going, Brandon."

I did. I was so horny that I was definitely not going to stop. I was going to fuck Joanna as soon as I made her cum. I was going to give her a pounding tonight.

I danced my tongue up and down beside her clit. Joanna quietly gasped her pleasure. I adjusted the timing of my licks, so she gasped at the same time as Kaitlyn. Kaitlyn's loud moans came clearly through the wall, so it was like I licked Joanna to pleasure Kaitlyn.

Kaitlyn's moans suddenly stopped. I kept on lapping Joanna's pussy, giving her clit special attention. I could hear her deep breaths now.

Thump! Kaitlyn and Paul were fucking now. Thump! Thump! Thump! I wanted to join them. I wanted to fuck Joanna silly. I continued working her clit until she quietly came. I could barely hear her over the sounds of Paul and Kaitlyn fucking.

When Joanna recovered, I climbed above her and guided my cock to her pussy. Normally, I let her guide me in, but tonight I wanted to fuck so bad that I guided myself to her hole. A push, a push, and a third push, and I was buried all the way in. Then I started fucking her hard, pounding her furiously. Now, I could shut out the sound of Kaitlyn and Paul fucking. I was totally focused on slamming into Joanna. I desperately needed to release the sexual tension by cumming in her. I fucked her like a dog fucks a bitch in heat until I exploded into her so hard that I saw stars.

When I was finished, I collapsed onto Joanna. She hugged me tight and laughed lightly in my ear. "So mine and Kaitlyn's plan worked for you?" She laughed some more. I joined in. As no sound of sex was coming from the other room, I could hear her clearly now.

I said, "So what exactly was your plan?"

"That reminds me," she said as she pushed on my chest to get me off of her. I pulled out of her and got off of the couch. She sat up and knocked three times on the wall to Kaitlyn's bedroom. Joanna looked at me and smiled. "That's the signal we fucked. We don't want Kaitlyn storming back out here."

I used a corner of the towel to clean the juices off my cock. Joanna took the towel in one hand and my hand in her other before leading me to our bedroom. I pulled back the covers and we got into bed. We lay on our sides facing each other. I stroked her face and said, "Your plan?"

"Oh, yeah! Well, I told Kaitlyn that last night they were so loud while we were in the middle of foreplay that it took you out of the mood. And I expected the same thing to happen tonight if we didn't do anything different. I suggested they slow down so we'd be the first ones to start having sex. Kaitlyn said she didn't think she could get Paul to slow down enough. So she came up with the idea of us doing foreplay together as a way of getting both couples on the same timeline. Once the foreplay was done, I was to have you eat me and then fuck right away." Joanna gave me a naughty grin. "The noise didn't seem to bother you this time."

"No, it didn't. If anything, it made the sex better for me. And for you?"

"The same. It was like they were cheering us on."

"How far were we supposed to go out there?"

"Kisses and feels. We were supposed to do lots of kissing, but Paul went almost right away for the feels." A concerned look came across her face. "Kaitlyn looked so sad as she watched you give me neck kisses. I hope you didn't mind me having you do the same for her."

"I was fine with it. It was Paul I was worried about. I was afraid he'd get angrily jealous even though I wasn't kissing Kaitlyn on the lips or feeling her up."

"Exactly! I kept telling Paul that while you were kissing Kaitlyn. He wanted to switch back and make out more, but Kaitlyn had other ideas."

I laughed. "She did. It was funny to hear her say 'Now' and to see Paul hustle to obey." We both laughed. I kissed Joanna and my feelings for her swelled. I was tempted to tell her that I loved her. With my other girlfriends, they had said, "I love you" before I was ready to say it. I wasn't certain Joanna was ready to hear me say it, so I didn't.

Instead, I made a circle around Joanna's tit and said, "I think we have time for another round."

"Oh no. Paul is a one-and-done guy and I promised Kaitlyn we wouldn't do a second round."

I arched my eyebrow. "Where was this consideration for the other couple last night?"

Joanna chuckled. "We didn't ask for any consideration then. Kaitlyn did today." Joanna moved close to me, pressing her body against mine as she kissed me sensually. "But I could suck you off if you promise to not make a sound."

* * * *

I didn't sleep well again. This time, I kept waking up to my mind replaying me kissing Kaitlyn. Once again, I felt the texture of her skin on my lips, and I heard her gasps. I was hard all night long.

* * * * Chapter 2 * * * *

To save me some comments and PM's: I've always heard people use "laying out" for sunning. It's apparently an American-only phrase. I know that's grammatically incorrect, but it's what sounds natural to me.

The next day, Monday, was beautiful for water skiing, and we had a great morning session. When Mom or Dad skied, Joanna sat next to me, and Kaitlyn taught her how to be a good lookout.

After lunch, it was nap time for Mom and Dad, which meant the rest of us had to hang out somewhere else for at least an hour. What Kaitlyn and I usually did was lay out on chaise lounges that were halfway between the lake house and the lake. While Mom and Dad cleaned up, Joanna and Kaitlyn went into their bedrooms to change into sunning bikinis. The difference in how busty Joanna and Kaitlyn were was even more obvious when they were in these bikinis. Still, Joanna looked good.

Once we left the lake house, Joanna, Kaitlyn, and I went to the chaise lounges while Paul went over to a hammock in the shade with his tablet. We sprayed sunscreen on each other and then lay down. As I hadn't slept well the last two nights, I was soon fast asleep.

"...to you?" I heard Kaitlyn say quietly.

"Oh, yes. He's done it a couple of times," Joanna replied, also quietly. It was like my subconscious had heard I was being discussed and had woken me up. I continued to act asleep. "The first time he did it was before we fucked for the first time."

Kaitlyn gasped. "You've been fucking?"

Joanna snickered quietly. I thought they were being quiet to not wake me. "For weeks."

"Slut! Why didn't you tell me?"

"Because it was so fun seeing you get bent out of shape. Consider it revenge for all the fashion shows at work."

"Revenge? Did my showing off what lingerie I was wearing bother you?"

"Hell yeah! 'See what expensive lingerie my boyfriend bought me this week.' You know I don't have anything like that. All my underwear I buy on sale at Wal-Mart."

"I should have known, Joanna. I'm sorry. Forgive me?"

"Sure. Forgive me?"

Kaitlyn laughed. "Sure. Even?"

"Even."

There was a pause. I started to drift back to sleep but perked up again when Kaitlyn said, "Did it bother you when Brandon kissed me?"

"No," said Joanna like it was obvious. "It was my suggestion."

"Would you...would you mind if he did it again tonight?"

I had conflicting feelings about kissing and nibbling on my sister. Part of me thought it was wrong, but it was easy to dismiss that as no one else had been upset about me doing it. What I eventually settled on that it was a stupid thing to have done, but I had done stupid things before and would do stupid things again, particularly after a few beers, so there was no point worrying about it.

Joanna asked, "What would Paul think of that?"

"After we had sex last night, he made a joke about me liking my brother kissing on me too much. I told him that he'd better hope that Brandon did it again as he wasn't putting me in the mood for sex."

"Ouch!"

Kaitlyn said in an angry hiss, "Yeah." Then her voice cooled. "Paul's not going to do anything that could result in him being cut off." She sighed. "And I don't want to cut him off as it'll ruin the vacation for everyone else. But I can't count on him to put me in the mood. He's not good with foreplay; he always wants to go straight to sex."

"And Brandon kissing on you certainly put you in the mood." Joanna cackled quietly. "So you want to do tonight like we did last night?"

"Yes."

"Last night was fun. I've never done anything like that before but would enjoy doing it again." Then in a teasing tone, "I'm okay with lending my awesome boyfriend to you for a few minutes."

"Thanks," said Kaitlyn gratefully. After a few moments, she added, "Brandon's been a good boyfriend for you."

"A good mercy boyfriend."

Kaitlyn sighed. "He's not doing anything with you because I've asked him to. He wouldn't make love to you unless he cares for you. He genuinely likes you, Joanna."

"Then why does he always go out with both of us instead of just me?" Because we all have more fun when it's all three of us, and Kaitlyn doesn't mind being a third wheel. "Why didn't he spend more money on me? Take me to nice restaurants? Buy me nice lingerie?" Because I'm a struggling college student working a minimum wage job. "Why did you keep pushing him to make love to me?"

After a long pause, Kaitlyn said in a pained tone, "Brandon doesn't spend lots of money on his girlfriends. He shows his affection in other ways. And you can tell he cares for you in the way he looks at you and pays attention to you. Every girlfriend he's had has enjoyed having him as a lover. I wanted you to have a very positive lovemaking experience." Kaitlyn's tone lightened up. "Am I your best friend or what?"

"You are my best friend," replied Joanna with warmth in her voice. "Have been for years."

The girls moved on to subjects I wasn't interested in. I was angered and frustrated that Joanna still considered me a mercy boyfriend. What did I have to do to convince her that I cared for her? I had been as loving and as affectionate with her as I had been with any other girlfriend. I was suddenly very glad I hadn't said "I love you" last night. She probably would have not returned it, which would have made things very awkward.

* * * *

In the afternoon, we went jet skiing. While Joanna and I were riding a two-person jet ski, she told me about Kaitlyn's request.

I said, "Aren't you bothered by me lightly making out with my sister?"

"No! It was my idea. It was harmless fun. Last night was a lot of harmless but very exciting fun. Kaitlyn and I want to do it again."

I felt it was a stupid thing to do, that we could wind up embarrassed about it. But having a group make-out party twice was no more embarrassing than doing it once. "Okay."

* * * *

After jet skiing, we had a wonderful dinner and an enjoyable post-dinner conversation. When Mom and Dad left, Kaitlyn said, "Chairs like last time" before she and Joanna disappeared into her bedroom. I felt apprehensive. Though I had enjoyed last night, I couldn't shake the feeling it had been wrong. I felt like tonight was going to be more wrong since we were sober, and I knew I was going to be lightly making out with my sister in front of my girlfriend and her boyfriend.

Paul said, "I wonder what they'll wear tonight."

I shrugged. I tried to convince myself that seeing Kaitlyn in a bra and panties was just like seeing her in a bikini, but I failed -- bra and panties felt forbidden, which made seeing her in them very exciting. Then I shook my head; we were going to have some harmless but exciting fun, just like Joanna said. No one would get angry; nothing to feel embarrassed about.

The door opened and I turned to see the girls come into the room. Joanna led this time, dressed in the same bra and panties as last time.

Paul said, "Nice. My favorites."

Once I got a good look at Kaitlyn, I could see why the bra and panties were his favorites. They were a dark blue which looked great against Kaitlyn's skin. The bra had a circle close to Kaitlyn's neck, a circle beneath her breasts and a clear mesh connecting the two circles that had a plunging 'V' in the middle. The mesh lightly held her breasts, and they shifted noticeably as she walked. The mesh had stars scattered across, two of which strategically covered Kaitlyn's nipples. I could see all of her tits except where the stars were. The panties had an inch-wide ribbon of silk across the top with lace beneath. Right in the middle, the lace was missing and instead there was a deep V that must end just above her pussy. Any doubts about whether Kaitlyn shaved were gone. She looked sexy as hell in her outfit. Kaitlyn knew how to strut her stuff, and she oozed sexuality as she sashayed.

When the girls reached the space between Paul and me, they again stopped for a moment before Joanna walked sultrily toward me as Kaitlyn did the same toward Paul. I smiled at Joanna. She did look sexy as she walked toward me, even if she was the moon to Kaitlyn's sun.

I was ready with a kiss when Joanna slipped into my lap. After our first kiss, Joanna moved forward and whispered into my ear, "Lots of kisses tonight" before kissing along my jawline back to my mouth.

I was happy to comply. I loved kissing her. She had soft, full lips that felt great against mine. After a few kisses, I heard Kaitlyn say, "Not yet, Paul". I tilted my head enough so I could look over and I saw Kaitlyn pulling Paul's hands down from her tits. I sympathized with Paul -- how could Kaitlyn expect him to keep his hands off her tits when she was wearing that bra?

I pushed Kaitlyn and Paul out of my mind and concentrated on kissing Joanna. We kept kissing on the lips, but in slightly different ways that made the kisses hotter and hotter. Sometimes she'd grab my bottom lip between her lips as I pulled away. Sometimes I did the same to her. Sometimes I'd run my tongue over her lip as soon as the kiss ended. The whole time we were kissing, I kept thinking of Kaitlyn and Paul doing the same thing on the other side of the room. I heard another, "Not yet, Paul", but I was so into kissing Joanna that I didn't look this time. She was more aggressive in her kisses tonight than normal, like kissing in front of Kaitlyn and Paul was getting her extra excited.

I heard Kaitlyn say, "Stay here and, in a little bit, we'll go to our bedroom." I stopped kissing Joanna; she got up and walked toward Paul. I got up too, making room for Kaitlyn to sit down. As soon as she was seated, I kissed her neck. She let out a small gasp and grabbed my hands, pulling them to the bottom of her rib cage. As I did the kissing and nibbling, I moved my hands slowly in circles. To my surprise, Kaitlyn reacted more strongly tonight than she had last night, getting much more into the kisses and nibbles.

While I was kissing along Kaitlyn's shoulder, I looked across the room. Joanna was seated on Paul's lap, and Paul was running his hands up her arms to her exposed shoulders. Joanna gave me a smile. Paul looked bored. I kept kissing along Kaitlyn's shoulder. This time, I kept kissing once I crossed her bra strap and kissed all the way to the end of her shoulder. When I was done, I stood up.

Joanna was the one who got up immediately this time. She took a few sensual steps toward me with a big smile on her face before reaching behind her and undoing her bra. She kept her eyes on my face as she peeled the bra off her and tossed it aside. When she reached us, Kaitlyn got out of the chair and left my vision as I stared at Joanna in amazement. Joanna rotated the chair ninety degrees and ordered, "Sit down." I sat down in the chair. Joanna immediately straddled my lap. She grabbed my head in both hands and said loudly, "Suck it!" as she guided my mouth to her tit. Her nipple was already hard before it entered my mouth. I sucked gently as I grabbed Joanna's ass firmly in my hands. This was so fucking insane. Last night had been crazy, but this was even crazier.

I happily sucked on Joanna's tit while squeezing her ass until she pushed back on my head. She guided to me her other tit, and I greedily sucked on it too. Last night had been hot, but tonight was far hotter. I wondered -- had tit-sucking been a part of the plan? Something they had decided on while they were in the bedroom changing into bras and panties? Joanna had walked toward me topless with total assurance.

Joanna pushed back on my head and again I let go of her tit. She guided my mouth back to her first tit, and at the same time, shifted toward Paul and Kaitlyn so I could see them easily. Kaitlyn's bra was off, and Paul was furiously sucking on the right tit, which was closest to us. I was shocked to see Kaitlyn was red-faced with anger. What was she so angry about? Were the guys frolicking on second base in front of the other couple too much for her? Was Paul doing something that made her angry?

Joanna said loud enough for Paul and Kaitlyn to hear, "Paul said it was boring to watch you kiss on Kaitlyn. He asked me to do something he'd find exciting. Do you find this exciting, Paul?" Paul nodded his head vigorously while continuing to suck on Kaitlyn's tit. Joanna laughed. She ran her hands through my hair and said quietly to me, "I hope you find this exciting. I find it very exciting."

Joanna twisted my head gently, so I was looking at Paul and Kaitlyn again. Anger was gone from Kaitlyn's face and it was replaced by something I couldn't place, but it wasn't pleasure. Paul was sucking on the left tit now, giving me an unobstructed side view of the right one. I had known my sister was well-endowed, but it still shocked me to see exactly how well-endowed she was, how proudly her tit stood out on her chest. Her areola was a light brown and looked larger than average in size. Her nipple was completely erect.

Joanna said quietly to me, "I think Kaitlyn wants you to look at her tits. I bet it's making her very excited. I'm sure she's jealous that you're sucking on my tits instead of hers." Joanna added gleefully, "I love making her jealous."

After I had suckled on Joanna for a bit, I couldn't resist looking back over at Kaitlyn and Paul. Paul was mouthing her left tit again while Kaitlyn was looking at me. We locked gazes. As we continued to stare at each other, I saw out of the corner of my eye Paul bringing up his hand to Kaitlyn's near tit. He started playing with the nipple, running his finger around it and tweaking it. It was like he was showing it off to me. The whole time, Kaitlyn moaned as lust filled her face.

Joanna said loudly, "What are you going to do tonight to your naughty girl, Brandon? Are you going to give me a hard fucking?" Hell yes! An odd look came over Kaitlyn's face. "How are you going to fuck me? Doggie-style? Doggie-style on the couch?" I didn't care where or how we fucked so long as we fucked. I had never wanted to fuck so badly in all my life. I couldn't wait to get my cock in Joanna's pussy. The odd look on Kaitlyn's face became one of longing. "How about you throw me over the arm of the couch and take me there? Would you like to do that?" Kaitlyn appeared to whimper, like she wanted me to throw her instead of Joanna over the arm of the couch and fuck her.
