Laughing we looked back at the couple before cleaning ourselves in the cool moonlit water of the lake. Then we sat by our own fire, just chilling. Finally we crashed out in our tent. Exhausted, naked and happy. During the night I had sex with my sister again, burying my cum deep in her cunt. We fell asleep again, before I woke up with the morning sunlight streaming through the open doors of our tent. There was no sign of my sister but I felt, then saw a hand on my cock. A dark brown hand. I loved the contrast of her dark skin against my light skin. I turned and smiled at Emily. She scooted over to me and we kissed, our hands roaming over our naked bodies. With her hand on my cock she looked me deep in the eyes. Her beautiful big wide eyes.
“Can I ask you a question? Maybe more than one,” she whispered.
“Sure.”
“Well I don’t know how to say this….”
“Try. We can’t have any secrets between us now.”
“Well, hear me out. I don’t want to say anything out of place but… and I know you have a girlfriend.”
“Hannah.”
“Hannah. I know you guys are steady and live together…. I just wondered…” she continued.
“Listen Emily…. I think I know….”
“I mean I’m not trying to split you guys up or anything….. I just wondered….,” Emily said nervously.
“We’d have to be careful…..” I interrupted.
“Huh?”
“I know what you’re trying to say. You want to do this again. When we’re back….”
“Yeah…,” she whispered.
“We’d have to be so careful. She’s got a lot of friends. I don’t want to split up with her either….” I said.
“You’re serious? I didn’t think…..” she exclaimed.
“We’ll have to meet up, when we get back. Let the dust settle a bit. See if we both still want it…. we need to work out a plan. Time and places. So we don’t get caught,” I told her.
“Are you ok… with cheating on your girlfriend? I thought you guys were…. you know…. tight….”
“We are. But right now I can’t imagine never doing this with you again.”
“What about your sister?”
“Well, I guess the same thing applies, I’ll need to sit down with her and talk and see how we both feel. I want to though.”
“Sure, I also meant….. are you going to let her know about us… if we do it? Do we need to keep it a secret from her as well? Us?”
“I don’t think so. Why?”
“Well I guess….. you know….. that it might be like it’s been here….. where the three of us get together and mess around. Which is cool, I want that. But I also want there to be times when it’s just us. You and me. I want us to fuck alone sometimes. No one else.”
“Emily, that’s cool. I guess there’ll be times when me and Ava do it alone. At my parents house when we get a chance, so yeah, I’d want to have time with you,” I reassured her, kissing her.
“What about your girlfriend then?”
“I’m gonna be busy trying to work out a plan!”
“Won’t she get suspicious?”
“I’ll…. we’ll be really careful.”
She kissed me back and we resumed touching each other. Before long we were fucking, with Emily on top, facing me.
A slight chuckle told us that my sister was back. She crouched in the tent entrance, watching us.
“Do you guys realise that apart from about two minutes, we’ve been nude for over twenty four hours?”
We both laughed.
“I wish it could continue. I wish we weren’t going home.”
My sister edged further into the tent and put her arms around her friend, placing her hands on her breasts. She played with Emily’s tits while I fucked her. Then my sister moved around to me and crouched over my face. I began to lick her pussy while still thrusting into her friend.
After a while they changed positions, me fucking my sister while Emily sat on my face. Then they took it in turns to lick my cock before they both crouched down and licked at my shaft. Both girls sat up and faced each other and began kissing while i slipped my cock between their mouths, before once again i thrust into Emily’s pussy while she licked Ava’s juicy cunt. I could take no more and my semen exploded into Em’s vagina and both girls climaxed. We lay in a hot, sweaty, sex smelling heap for ages, finally falling asleep. We were woken by voices at the tent entrance.
David and Sarah were both standing there staring at us. They were still nude.
“Erm…. we wanted to thank you….. for…. err….. last night….” stuttered Sarah.
“Er….” I mumbled.
“Well, we’re both getting old now, we don’t get to have much sex. Don’t feel like it really, so last night was both surprising and fun. So thank you. The most fun we’ve had in years.”
