Keith: The first time Jenna and I were away from each other was our freshman year in college. I got a baseball scholarship to State, while she went to Atlantic for its fine arts program. I missed her dearly; we called and emailed each other all the time, just to see what the other was up to. We kept no secrets from each other.

Jenna: I always thought about Keith. When we were kids, we did everything together. On my first date, I insisted he and his girlfriend come along with me. He’s my twin brother, and my best friend, and I hadn’t seen him since Christmas Break.

Keith: Jenna had already been home from school for two weeks by the time baseball season ended. I had a decent rookie season, but we didn’t make the conference playoffs. I was a little down, but when I got home, she jumped into my arms like, well, like we hadn’t seen each other since Christmas Break.

Jenna: He pulled into the driveway. I was so happy to see him. I couldn’t wait to tell him about my spring semester. I got A’s in all my art classes. I saw him get out of the car… I forgot how handsome he was. He seemed to have bulked out and filled out over the year. I wonder how he resisted all the co-eds who threw themselves at him.

Keith: All I remember is she jumped into my arms and gave me a big wet kiss on the cheek. When we broke our embrace, I took a good long look at her. My twin sister was more beautiful than I remember. She told me a lot of guys hit on her at school, and that there was one man she slept with. But the Jenna I knew had some scruples; she’d never sleep with a guy she didn’t like.

Keith: I wasn’t feeling well the next morning, so after Jenna and I had breakfast, I went to lie down. When I woke up, I saw she left a note on my nightstand saying she was at the pool. My room faced the back of the house, and I glanced out the window.

Jenna: Just for kicks, I took my bikini top off. I don’t know what possessed me to do it, probably the lack of tan lines. Hell, it was just me and Keith, and I didn’t care if he saw me topless. I mean we’ve seen each other naked before, so it was no big deal. But that was when we were kids. We are adults now, and I admit, the thought of him seeing me naked was a bit of a turn on.

Keith: So there she was, sitting by the pool topless, her perfectly round breasts tanning in the sun. Then she started running her hands around her breasts slowly, like she was trying to turn herself on. I wonder what she was thinking. I felt my penis getting hard. She slowly moved her hands off her breasts and down her body, then between her legs. I couldn’t believe what I was seeing. I tried to turn away, but I was so aroused I couldn’t help myself. I started to stroke my penis while I watched my twin sister pleasure herself. Did she know I was watching her?

Jenna: Of course I knew he was watching me! I could picture him jerking off while I felt myself. I couldn’t help but be turned on, and the more I thought about him watching me, the more aroused I got. I started to feel myself getting wet. I was tempted to go underneath my bikini, but something in my head held me back. I closed my eyes and imagined Keith masturbating as he stood over me, and I became even more turned on. As I imagined him cumming all over me, I exploded with ecstasy.

Keith: As I watched her feeling herself, I couldn’t help myself to keep jerking off. She writhed with pleasure as she felt her breasts and pussy. I imagined myself beside her, with her hand on my cock and mine in her pussy. And by the time I heard her orgasm, I had cum all over myself.

Jenna: It felt really weird, thinking of my twin brother in a sexual way, but I didn’t feel guilty. If anything, I felt closer to Keith than ever before.

Keith: I took a quick shower, threw on my swimming trunks, and went down to the pool. Jenna looked at me with a big smile on her face. As I lay down next to her, I asked, “Did you do what I think you did?”

Jenna: “That depends. Did you do what I hope you did?” I reached over and held his hand. “Did you…?”

Keith: I didn’t even wait for her to finish. “Oh, God, yes.”

Jenna: “Me too.” I hesitated before I added, “Next time, we have to do that together.”

Keith: “How does tomorrow sound?” I figured as long as my parents were at work during the day, we’d be okay. They would have gone nuts if they ever found out what we did.

Jenna: The next morning, Keith and I went to the supermarket to pick up some things that Mom needed. Basic necessities like milk, cereal, some vegetables and fruits. Keith got some salmon for dinner. I couldn’t help but to think about yesterday.
When we got home, after we put away the groceries, we went to our rooms to change into our swimsuits. I didn’t bother closing the door, and I don’t think he did either. We held hands as we went downstairs to the pool.

Keith: “Damn, I have to go get the sunscreen.

BRB.”

Jenna: “Don’t keep me waiting,” I said seductively. “And don’t speak in web-ese.”

Keith: By the time I returned with the sunscreen, Jenna had already pulled out the lounge chairs and stretched a towel on each one. I tossed her a bottle of 15 SPF. I preferred 8 because I didn’t burn as easily. I rubbed the lotion pretty much everywhere I could reach. I noticed Jenna was doing the same. Then she held up her bottle. “Empty?” I asked. She said, “No, I need you to do my back. So she sat on the lounge chair, and I squatted behind her.

Jenna: The lotion was cold as Keith squirted it on my back. His strong hands rubbed the lotion from my neck all the way down to the edge of my bikini bottom. He untied my top and rubbed where the strings were. Then he did something I didn’t expect him to do, but hoped he would. His hands wrapped around my body and rubbed the sunscreen into my breasts. It felt so wonderful, so comfortable, so relaxing. I leaned back into him to make it easier to massage my breasts. I moaned and said softly, “That’s nice. That’s perfect.”

Keith: The great thing about living in small-town America is that homes are so spread out. Each home came with at plenty of land, so neighbors had plenty of privacy. Our nearest neighbor was a good 300 yards away, so no one could watch what Jenna and I were doing. My cock started to stiffen as I massaged Jenna’s breasts. I had a feeling what was coming her next. Jenna started feeling around my swimming trunks, trying to pull them down. “There’s an easier way to do that,” I said, pushing her up.

Jenna: He pushed me up and stood facing me. I could see through his trunks he was hard as a baseball bat. I untied the drawstring and slowly pulled his trunks down to the ground. His cock almost hit me in the face as it sprang into action. I ran my fingers up and down his shaft. Suddenly, I wasn’t relaxed anymore; I was horny as all hell! I’d seen my brother naked before, but never quite like this. I leaned into him and rubbed his cock between my tits. No more imagining what it would be like to be with Keith. This was it!

Keith: Jenna grabbed a bottle of SPF 8 and rubbed it up and down my shaft and around my balls. I looked at her with wide eyes. “What?” she said. “You don’t want it to burn, do you?” I couldn’t help but laugh at the innocence and taboo of what we were doing. I asked her to stand up. She looked at me strangely.

Jenna: I thought, why the hell would he want me to stop? But I obliged my brother. As I stood, he inserted a finger between each thigh and my bikini bottom. Without moving his hands, my bikini slid down my legs. He let go, and it fell to the ground. I sat on his lap, just in front of his rock hard cock. I teased it as if I was giving him a lap dance.

Keith: I felt like I was going to explode, but I didn’t want to. Not yet, anyway. I started licking her erect nipples. They tasted wonderful. She put her finger under my chin and tilted my head up slightly. She leaned into me and kissed me passionately. It was heavenly! We continued to masturbate each other. When I stuck my middle finger into her pussy, she let out this gasp that I never heard before. At first I thought I had hurt her, but the smile of pure delight erased my fears.

Jenna: I was in heaven! The deeper his fingers penetrated into me, the more I wanted him inside me. I gently pulled his fingers out, reached for his cock, and guided it inside me. Keith laid back as I moved back and forth, up and down. We didn’t have a condom, so I knew we had to be careful.

Keith: It seemed Jenna was doing most of the work, so I decided it was time to pleasure her a little bit. I raised my hips, signaling for her to get off of me. She stretched a towel on the grass next to the lounge chairs, then she laid down. I climbed on top of her and started driving my cock into her, first slowly, then with more energy. I could tell from the look on her face that she was enjoying it as much as I was. After a few minutes, I felt a tingling sensation, and I knew it was time to pull out. I grabbed my cock, stroked it a couple of times, and came all over her tits and stomach. Jenna gasped and smiled. She took some of the cum in her fingers and placed them in her mouth. “Mmmmmmm,” she said. “You taste incredible.”

Jenna: We laid next to each other, naked, for some time after that, our fingers exploring the other’s body. “I love you, brother,” I said. He replied, “And I love you, sister.”

Jenna: We made love several times more that summer. Then we were back in college. Me at Atlantic, Keith at State. I missed him so much. Some nights, when I masturbated, I could feel him inside me. When I slept with guys at Atlantic, I would sometimes picture Keith. It was weird, but the guys never seemed to notice.

Keith: Jenna and I are the only two people in the world who know what we did that summer. We’re both married now, with children. Jenna wasn’t my first, nor my last, but she will always be my best. The summer we spent after our freshman year was pure magic.
