For a couple of weeks, I had planned a weekend visit to my sister, Helen. Hubby was taking care of our teenage daughter back home. Here I was, pulling into her drive after the two-hour drive. We hadn't really planned to do much, just visit, dinner at a nice restaurant, a hike in a park, maybe shop. But there was another car in the drive, and when she let me in, there was a guy sitting on the sofa.

"Hi, Bobby," she said as we hugged each other. "Oh, this is my boyfriend, Luther. I've told you about him," she added. She most definitely told me about him. To hear her tell, he was an incredible lover, and she didn't hold back on the details, which always got me aroused.

Luther stood to greet me, his smoky grey eyes drilling right through my head. "Wow, Bobby, you're as beautiful as your sister," he offered as he shook my hand.

"You're as hot as she said," I thought but didn't say. "Thank you," I gushed. Were my panties getting wet? Sis is six years younger than me. Her boyfriend seemed to be even younger.

Helen rescued me. "We saved dinner for you. It's just a crockpot stew, but Luther brought a nice red wine to go with it."

While she putzed around in the kitchen, Luther and I sat across from each other at the table. "You've been dating her for what, a couple months?"

"Yes. Yes, we have. Maybe three."

"I'm so happy for her," I said. Feeling incredibly envious, I thought, "Thou shalt not covet." My own hubby was no way near as attractive, and not the bedmate that Helen had described. But we got along and shared the responsibility of raising and trying to control our daughter who was approaching sixteen.

"So you're a carpenter?" I asked, confirming what Helen had told me.

"Yep. I'm good with a hammer and nail," he replied. With a glint that brought forth an old robot joke, "And a screwdriver. ... You're a machine operator, Helen tells me?" Seeing Luther face to face, imagining the fun Helen had described, my mind had transferred those visions and put Luther between my legs. My hand rested on my thigh resisting the move my suddenly soaked pussy wanted. I wanted the unobtainable. The off-color joke. Then I realized he had asked a question. "Oh. Yeah. I am."

The dinner conversation was lively and mostly involved Luther and me learning each other’s life history, careers, and activities. Helen seemed to encourage that, offering tidbits about each of us as the meal went on. Luther's wine disappeared from our glasses, so when she served a cherry pie, Helen brought out a nice Riesling. I could have used a coffee, but the wine went down smoothly. I caught myself staring at Luther as I slowly slid red cherries from the pie into my mouth. Did he realize my folds were begging for his presence there? Oh God, Helen winked at me. Was I so obvious?

"Why don't we sit on the sofa?" she suggested. We all finished clearing the table. Luther and I brought our wine glasses. We sat next to each other, leaving space for Helen once she was done with a few things in the kitchen. It was a little tight for three, but I didn't mind being pressed against Luther's body. Luther didn't seem to mind being squeezed between two ladies. In fact, I swore there was an arousal in his lap. Would the two of them be excusing themselves to take care of that?

Helen sat long enough to finish her wine but then dropped a shocker. She leaned over, rested a hand on his leg, kissed him politely, and said, "I'm getting tired, and you two seem to be hitting it off. I'm gonna go up and read a book."

After she left, I turned to stare into Luther's eyes. "Did she mean what I thought she meant?" I asked.

Luther reached across to my shoulder and pulled me toward him. "So it would seem."

We stared at each other for seconds that seemed like minutes. The feeling behind my pubic bone grew stronger.

"I don’t think this is a g...," I started to say before his kiss cut me off. It had been several years since I had last crossed the line with an old boyfriend, but the rush, the heat, and the passion were all there again. I wanted this man and realized he was going to have me ... with my sister's blessing. I would have to deal with the guilt later.

I grabbed Luther's shirt as our tongues played. His hands found my breasts through my top and squeezed. I started to unbutton his shirt. His chest was magnificent. After I finished the lowest button, my hand surrounded the bulge in his pants. My own top was coming open. His hands wandered over my bra, then tugged the top down past my nipples. He took one of them in his lips and expertly reached behind me to unhook my bra.

I had to feel that shaft. I undid his belt, button, and zipper and slid my hand into his boxers. It was definitely above average. I glanced down to see what had been revealed so far. There was some moisture on the tip.

A hand was on the bare part of my leg below my shorts. Then it was over my mound. I felt my belly getting even tighter inside. I reached down and opened my own shorts; I couldn't wait to feel that hand exploring me. The gesture wasn't missed. He lightly passed his hand over my damp panties. Even so early in our foreplay, my hips rocked up against it. I slid my shorts down over my knees and wriggled them all the way off. My aroma was already in my nostrils. Luther pulled off my panties.

I got Luther’s cock all the way out. He helped me take down his pants. He hooked the waistband of his boxers below his balls. His kisses left my tits. He grabbed my leg and pulled it across, so he was between my thighs. I was able to cling to his cock while he held my leg up and kissed his way up my calves and thighs. My hips were rocking even before he touched my pussy. As I yanked his shaft compulsively, he used his tongue between my labia and my thighs. He found my clit. Two fingers went in me. I moaned out loud. Oh god, could Helen hear us? Staying on was getting awkward for him, so I just grabbed his head with both hands and pulled him in deeper. His tongue worked up and down between my lips 'til he took his fingers out. He ran his tongue around my opening. I pulled his head deeper into my flesh as his tongue played inside me. I was thrashing so hard, he had trouble keeping it there.

Then my orgasm subsided. He climbed up over me to kiss, his face wet from below. I let him kiss me for a few seconds, then pushed him over to a sitting position on the sofa. I moved across his leg to kneel on the floor in front of his cock. He loved having me suck his balls, lick his shaft, and take his tip in my mouth. I bobbed and sucked and slurped for several minutes to his groaning delight.

But before it went too far, I stopped and said, "I want it in my pussy, first. We can get back to this later." I went around the coffee table, tossed off what remained of my clothes, grabbed his hand, and dragged him off the sofa. "Fuck me, Luther. Fuck me missionary. In the guest room."

We closed the door to the guest room. I pulled the bed covers back, lay down on my back, knees up, thighs apart. Luther tossed the rest of his clothes and climbed up on the bed. He moved between my legs and started kissing my uplifted knee, then my inner thighs, a brief kiss on my pussy. His tongue circled both nipples. I felt his cock touch my labia. He had it in his hand. He was using it to stroke there, to slide up and down between my labia, crossing my opening several times, rimming my butt hole, then up to my clit. He played there forever. The orgasm that had been building blossomed. My body was on fire down to my feet. The tip was at my opening. My feet pushed my back off the bed. It was sliding into me. It was a perfect size for me. It reached my cervix. I dropped down and pushed back up. He pulled out and slid back in. I arched up off the bed to match each thrust. I'm sure Helen heard my screams. I was cumming and cumming and cumming.

Without pulling out, he dragged my leg across him and got me on my side. Plunging, plunging. God, I was still cumming. "So good. So good," I moaned as his thrusts became erratic, his moans coming from deep in his body as he fucked me sideways. It was happening. Each stroke pumped his juices onto my cervix. The semen lined my vagina, providing even more lubrication. My orgasm came down. He didn’t have anything left, either. He was still stroking me. It felt so great post-climax. His plunges forced cum out of my hole. I felt it running down onto my thigh. I felt his dick getting softer, but he still drove it in and out. Then he flopped out.

We collapsed on our sides next to each other, kissing, caressing, my breasts on fire in his hands, his partly engorged cock slithery in my hand, hot juices running onto my left thigh. I knew what I had to do. I knew what I wanted to do. I pushed him onto his back. Kissed his hairy chest, his belly, his balls, his shaft. I gnawed on it sideways. The tastes of our love filled my mouth and nostrils. I wrapped my lips around the tip. He arched his back, and his cock filled my mouth. It was already getting harder. Sucking and slurping. "Don't stop. Don't stop," he begged. My hand played in my mess down below. It took a while but then we were both cumming again, Luther in my throat. I just swallowed everything.

We just laid there exhausted until I suggested maybe we have a drink. It seemed like Helen had been listening. When we had been quiet for a while she poked her head into the guest room. Luther and I were getting dressed, but it wasn't like we could hide what had been happening. "I hope you both had some fun," she said. We stared at her; apparently, she was only wearing a robe, lightly closed and exposing the space between her breasts. Luther and I stared at each other; then we started laughing.

In the kitchen, Helen poured Bailey's for all three of us. After a few sips, Helen wrapped her arms around Luther from behind and grabbed at his crotch. "I told you Luther is a great fuck," she added while kissing his neck. "Let's see how he handles two girls."

I'd had foursomes with Helen before, swapping included, but as it turned out, never a threesome. One time, after she turned sixteen, I even arranged a date for her with a grad student I knew. My date made a foursome. Even at that age, in my apartment, I saw she knew how to please a cock. After both couples had sex, my date took a turn with her, and hers found his place inside me.

Helen led us into the dining room and gestured for me to sit on the table. She joined me there and waited for Luther to go to work. He played with her tits through the robe and then pulled it open. As he sucked on her tits, I slid my panties back off and opened my top. As he opened Helen's robe further, it was confirmed that was all she had on. I always thought Helen had a nice pussy, a little plump with lips that covered all the inside folds, matching her D sized tits. He pushed her to lay on her back on the table and held her legs up. He leaned down to kiss her thighs; then he kissed her pussy lips. I reached down to play with myself. I watched him lick beside each of her lips and then suck them in. A brief spasm contracted her belly every few seconds. I was already breathing harder myself.

As Luther started to lick between Helen's lips, he opened his pants. He must have left his belt and shoes in the other room, because his pants quickly dropped to the floor and came off. He finally remembered I was there, and reaching with both arms, he inserted fingers in both me and Helen. I wanted his cock, but it was Helen's turn. Removing his fingers, he held it in place and stroked his tip where his tongue had been at work. Helen was bucking. Then I watched it disappear as it slid into her hole. His fingers fucked me at the same pace as his cock worked her.

After Helen's orgasm subsided, Luther pulled out and moved between my legs. He set his cock in my opening and with both hands, pushed up my bra. I fell back, looked over at Helen, and exchanged huge smiles with her. As he squeezed my nipples, he drove his shaft home. A huge contraction gripped my body and my smile was replaced with gritted teeth. I came instantly.

"Let's go to my bedroom," Helen suggested. The covers were already in disarray after she had laid there listening to Luther and me in the guest room. There was a spot on her sheet that made it clear she hadn't just listened to us. We all dispensed with what remained of our clothes and guided Luther to lay on his back. Each of us girls took a turn rubbing his cock. Then we started licking it, one on each side. Helen took it in her mouth for a few seconds; then, I did. Luther's hands managed to find both wet pussies and started us on the way to cumming again. Helen didn't just want fingers inside her and moved across to straddle Luther. I stroked his cock and held it up for Helen. She slid down until her pussy lips hit my hand.

I lifted my legs across Luther's chest as I began to play with Helen's clit. She was bouncing down and up on his shaft with my hand riding up and down with her. Luther's tongue played with my cunt as I backed down to his face. Helen's cum juices sprayed on Luther's balls and wetted my fingers. Then, he roared while his white cream oozed out along his thrusting shaft. My own juices, mixed with his from earlier, were running into his mouth as his thumbs pushed my lips over my clit. His tongue rimmed and fucked my love hole 'til I came full on.

Helen and I collapsed beside Luther on our sides. We took turns kissing him and stroking his slimy limp organ. He played with our tits. Eventually, his dick got a little fatter. I straddled his legs and continued to stroke him until he was ready for me. As I eased down, Helen climbed across his face looking away from me. I watched his tongue tease her clit. Luther and me fucked until Helen came again. Then he pushed us off and got us on our knees. His cock slammed back into me while he jammed three fingers into Helen's cunt. Helen's fingers reached under me and rubbed me. I was cumming when I felt Luther burst forth inside me.

I can't tell you how many times Luther fucked us that weekend. I was sore sitting in the car while I drove home to my husband. I tried not to reveal I was hurting when he wanted sex right after our daughter went to bed. At least I had cleaned up in Helen's shower.
