“What the hell are you doing, Kim?” I said.

“I’m offering you a blow job for twenty bucks. I understand you have a thing for streetwalkers in stockings.”

I heard Penny giggle and looked at her. She rubbed my crotch and said, “I’d give her twenty dollars if I were you.”

Kim knelt between my legs and moved her hands up my legs into my baggy shorts. She wrapped her hand around my cock and pulled it out from the leg opening. Looking up, she stroked my dick and smiled.

“You weren’t kidding, Penny. Brad has a beautiful big cock.”

I sat there dumbfounded as I watched my sister stroke my cock. Penny leaned against me, watching Kim.

Turning to Penny, I said, “You told her how we met?”

“Penny told me everything. I’m so proud of you for how you saved our cousin. The more we talked, the more she told me about you two. I told Penny that I’d always had a crush on you and how I used to try to tease you when we lived at home. It was so frustrating when you didn’t react.”

“When Kim told me how she felt, I told her to go for it.” Penny kissed me. “I think you should make her dreams come true like you’ve made mine come true. Whatever you decide won’t affect my feelings for you, baby. You have so much love to give, and I’m more than willing to share.”

I was having trouble processing everything. My sister was playing with my cock, and Penny was telling me it was okay with her. Having Kim play with me was a dream I never felt would come to fruition. The many times I masturbated while thinking of Kim couldn’t compare to how it felt at the moment.

“I used to think about you when we were younger, Kim. I guess I was too stupid to realize that you were teasing me when you’d let me see you in your underwear. You’ll never know how many nights I jacked off while thinking about you.”

Kim smiled, nodded, and leaned forward. She took my cock in her mouth, bobbed her head a few times, then took me into her throat. Kim moaned, sending vibrations through my body. She removed her mouth and looked at me.

“So, do you think I’m worth twenty dollars for a blow job?”

Laughing, I said, “Sorry, I don’t have any money on me.”

Kim gripped my shorts, pulled them off, and smiled. “Your credit’s good.” She dropped her head and started sucking my cock again.

Penny had moved away and was leaning against the armrest of the loveseat. She pulled her thong aside and played with her pussy while my sister blew me. I smiled at Penny and saw her nodding her head. Looking into my eyes, she gripped the hem of her tank top and removed it.

I ran my fingers through my sister’s hair as she sucked my cock and fondled my balls. Running a hand down her neck to her back, I located Kim’s bra strap. I pinched the closure, releasing it. Kim removed her mouth, sat back, and let her bra slide down her arms and off. Smiling, she held her breasts, letting me see them for the first time.

“Nice tits, Kim,” I said.

“Thanks.” Kim returned her mouth to my cock and sucked me in.

My sister continued blowing me until I was close to coming. When I warned her, Kim increased her effort. She rubbed my balls against her chin and moaned with my cock in her throat. I warned her again, but she didn’t stop.

When I could no longer hold back, I came and sent several spurts of semen into Kim’s mouth. She clamped her lips around my shaft just behind the head and looked into my eyes. When my cock stopped surging, she removed her mouth and kept her lips sealed. Kim swallowed my cum and smiled.

In a move I didn’t know how she’d react to, I pulled Kim onto my lap and kissed her. She seemed shocked for a moment but relaxed and parted her lips when I probed her with my tongue. She moaned as our tongues danced in her mouth.

After we kissed for a few minutes, I moved Kim off my legs, and she stood in front of me. Reaching to her waist, I gripped the thin waistband of her thong and pulled it down her legs. When the flimsy garment reached her knees, she removed her shoes and let the thong drop to her ankles. Kicking it away, my sister stood with her legs slightly parted, wearing her stockings and garter. I moved my eyes from her crotch to her face and smiled.

Kim giggled. “I can’t tell you how many times I almost stripped naked when we lived at home. The only reason I didn’t was I thought you’d think I was crazy and hate me.”

I smiled. “You look much better than I imagined. I used to think about how you’d look naked.”

“It looks like both of you got what you wanted,” Penny said.

I moved to the center of the loveseat and had Penny and Kim sit on either side of me. I put my arms around their shoulders, dropped my hands to their chests, and held their beasts. They wiggled against me, placed their hand between my legs, and fondled me.

“So now what?” I said.

Penny and Kim looked around me and smiled at each other. They kissed my cheeks and squeezed my cock and balls. Penny gripped my chin, turned my head to her, and kissed me.

“I hope you are up to taking care of two horny women. Kim and I agreed to share your love and body if it’s okay with you. I know we blindsided you, and I hope you’re not upset with us,” Penny said.

“Honestly, I don’t know what to think. In the past weeks, I’ve gained a girlfriend and lover. Then, my sister gave me a blow job. I assure you I’m not upset. Confused, but not upset.” I chuckled and squeezed their breasts. “As far as taking care of two horny women, I’ll do my best.”

“Penny told me about your naturist lifestyle. I can’t wait to join you two if you’ll let me,” Kim said.

I laughed. “Let me see. I get to live with two sexy naked women and take care of them. I think I can handle it. Kim, I want you to know I have no issues with incest. If you want to continue, and Penny doesn’t mind, I’m all for it.”

Penny stroked my cock, causing it to grow. “Didn’t I tell you Brad was the best man in the world? How can you help loving him and his openness? I don’t mind at all.” Penny waggled my cock. “There’s a lot of him to go around.”

“My brother has the best cock I’ve ever seen. I wasn’t sure I’d be able to deep throat him.”

“You did great, Kim.”

“So, is there anything off limits? I don’t want to do anything you don’t want or like,” Kim said.

“At this point, I only have one rule. When I wake up in the morning, Penny will be in bed with me. I don’t care if you’re with us, but I won’t spend the night without her.”

Penny kissed me. “Do you see now? Do you see why I love him so much? Baby, you’ll never wake up without me if that’s what you want.” Penny giggled. “We may have your sister in bed with us, but I’ll always be there.”

I put my hand on Kim’s leg and unfastened one of the clips holding her stockings. “I want to see you naked.”

Kim stood, unfastened her garter suspenders, and rolled her stockings down her legs. She removed the garter belt and stood before me completely naked. I smiled as she turned around to show me her ass. Penny continued stroking my cock while we watched my sister. The two girls grinned at each other, and Penny nodded.

Kim knelt on the loveseat with one leg on either side of my legs, Penny released my cock, and my sister gripped me. She put a hand on my shoulder, lowered herself, and rubbed my dick against her vulva. Taking a deep breath, she placed my cock at her entrance and moved down.

I held Kim’s sides as she impaled herself on my cock. She wiggled her hips and moaned as I filled her pussy. When our bodies met, she sighed. Kim remained still for a moment before she began moving. I held her, guiding her up and down as she fucked me.

“Oh my god!” Kim said.

“Isn’t it the best?” Penny said.

“I never knew anything could feel this good, Penny. I never thought I’d give my virginity to my brother.”

I stopped Kim’s movements. “What!”

Kim smiled and said, “I’ve never fucked before. I’ve used dildos, but yours is the first real cock I ever felt in my pussy. I gave my few dates hand jobs and head in hopes that it would be you someday.”

“What do you mean by your few dates? After you blew me, I felt you had a lot of experience.”

Penny chuckled and put her hand on my shoulder. “Go ahead and tell him, Kim.”

“I’ve had a lot of experience with toys but not real cocks. I only dated the few times I did, so Mom would stop bugging me.” Kim laughed. “I think she was afraid I was a lesbian.”

“Are you?”

“Obviously not.” Kim began moving. “Bi, but not a lesbian.”

Looking at Kim, I said, “Have you and Penny ever been together?”

Penny laughed and said, “Not yet. I plan to try if you’re okay with it.”

Deciding Kim and Penny had been talking about things I wasn’t privy to, I said, “I’ve always dreamed about a threesome.”

“Penny and I have agreed to make your dreams come true if it’s what you want. Right now, I need you to fuck your sister like you mean it. I’ve waited long enough to have a real cock. You don’t have to worry about knocking me up. I’m on the pill.”

I wrapped my arms around Kim and started putting her on her back. Penny jumped out of the way and knelt on the floor to watch. Kneeling between my sister’s legs, I began fucking her in earnest. Kim’s legs flailed as she shouted, begging me to fuck her.

Putting my hands on the backs of her legs, I pushed them up along her sides. She held my shoulders as I sped up, thrusting into her. She flopped her head from side to side and continued begging me.

I fucked my sister for another fifteen minutes before I felt my climax building. Kim’s body began quivering, and her legs shook as her orgasm built. While my sister came, I continued moving. I managed to get her off again before coming and filling her pussy. I released Kim’s legs and lowered my body to hers. She held me and gasped for air as she recovered.

Holding Kim, I kissed her. She hugged me and kissed me back. It took several minutes for her to regain her composure. When her breathing returned to normal, I moved off her body.

“Oh, my fucking god, Penny. How are you even alive?” Kim said.

“I warned you when you told me you never fucked before, Kim.”

“You did, but I didn’t think you were serious.” Kim chuckled. “I’m afraid to move because I’m going to leak on the loveseat.”

I moved to the floor beside Penny, grabbed my sister’s legs, and pushed them back. When I dropped my head to her crotch and began sucking and licking her pussy, Kim screamed. She wiggled and rocked her hips as I cleaned her pussy. While I was between Kim’s legs, I felt Penny sucking my cock. After a few minutes, Kim came again and begged me to stop. When I lifted my head, I looked down at Penny. She was lying on her side, bobbing her head on my soft dick.

Pulling Penny up, I put my arms around her and pulled her against my side. She kissed me and smiled. “Sorry. I wanted this to be you and Kim, but I couldn’t resist sucking your cock.”

“How many times do I have to tell you that you never have to be sorry about sucking my cock?” I looked at Kim. “The same goes for you, Kim.”

“I think we should introduce your sexy sister to the joy of skinny dipping, Brad.”

“You’re right, baby, we should. Come on, Kim, it’s time to get wet.”

Kim got up and laughed. “If I get any wetter, I’ll drown!”

We went outside, jumped into the pool, and let the cool water refresh us. After milling around, Kim came over to Penny and me. She hugged us, rested her head against our shoulders, and sighed.

“I’m so grateful that you two invited me to live with you,” Kim said.

“What would you have done if Penny and I didn’t offer you a place to stay?”

Kim chuckled. “I would have rented an apartment and lived alone.”

“I thought you were against living alone or in the dorms,” I said.

“I am against living in a dorm or with a roommate. My dream has always been to live with you, Brad. I thought I’d lost my chance when I learned Penny was living here, but she said she was okay with it when I mentioned it. It was before I told her about my fantasy of having sex with you.

“Once I knew Penny wouldn’t mind, I started telling Mom and Dad I didn’t want to live in a dorm, move to Phoenix, or live alone.”

“After Kim told me she didn’t want to live in those places, I asked you about asking her to live here with us. I didn’t lie when I told you it was because I wanted to get to know my family. I did. Once you agreed, Kim and I talked more.”

“I confessed my feelings about you, Brad. After we talked a few times, Penny said she’d be happy to share you. She told me about how you met and saved her. When Penny told me about your naturist lifestyle, I told her I could accept it if it meant living with you. Once I moved in, Penny suggested what I did tonight. It couldn’t have turned out any better.”

“I agree. It was so hot watching Kim suck your cock and fuck you,” Penny said.

“So, just how long have you been planning this, Kim?” I said.

Grinning, Kim said, “I started when Dad said he planned to move. I wasn’t sure you and I would ever have sex, but I started taking the pill just in case. If it didn’t work out with you, I was going to find a guy to take my virginity. As it turned out, the person I wanted most fucked me the first time.”

“I hope I didn’t disappoint you, Kim,” I said.

“Are you fucking kidding me! I never expected it to be as great as it was. You rocked my world.” Kim laughed and put her hand on Penny’s shoulder. “I thought I’d faint when you went down on me after fucking me and coming in my pussy.”

“I think you’ll find my sweetie is an equal opportunity lover. I love sucking his cock after he fucks me. It was tasty sucking him after he fucked you. I’m getting waterlogged. Let’s shower and relax. I need a drink,” Penny said.

We left the pool and went to the pool house to shower. When Kim headed to the other room, Penny grabbed her and pulled her in with us. I started the shower, and we stood under the spray. When Penny picked up the soap and began washing Kim, I stood back and watched. I felt my cock twitch when Penny rubbed the soap on Kim’s breasts. After watching for a moment, I moved behind Kim, took the soap from Penny, and washed my sister’s back and ass.

“This is amazing,” Kim said.

“I happen to think so,” I said, then handed the soap to my sister.

Kim didn’t hesitate as she rubbed the soap on Penny’s chest. She moved her hand down to Penny’s crotch and washed her pussy as Penny had done to her. When they finished, the two girls washed me, making sure my genitals were very clean.

“How many times can you get your big cock up?” Kim asked as she stroked my erection with her soapy hand.

“Brad can get it up more often than any other guy I knew. I didn’t know many, but my baby can go several times a day,” Penny said.

We finished in the shower, dried ourselves, and went to the patio. I went into the house to get three glasses, ice, and a bottle of whiskey. When I returned, I poured the drinks and gave each girl one.

“How often do you guys run around naked?” Kim asked after sipping her drink.

“As often as we can. I love being naked unless Brad wants me to wear my sexy undies. I really think he has an underwear fetish,” Penny said.

Kim laughed. “You wouldn’t know it by the way he acted when I let him see me in my bra and panties when I was younger, Penny. He would get so flustered.”

I looked at my sister and said, “What I did was go to my room and jack off while thinking about my naked sister.”

“I don’t think you’ll have to jack off anymore. Kim and I will keep you drained,” Penny said.

Kim sipped her drink. When I looked at her, she seemed deep in thought. I was about to ask what was wrong when she spoke.

“As long as this has been a night to share, I have something to tell, or rather, show you guys. Can you get the internet on the big television in the family room?” Kim said.

“Sure. I connect a laptop with an HDMI cable. What do you need?”

“Let’s go in, and I’ll show you,” Kim said.

We finished our drinks, leaving the glasses in the kitchen on the way to the family room. I went to my office, grabbed my laptop and an HDMI cable, then went...
