Well we weren't sure what to say honestly, was this just gonna happen sooner or later no matter what, or should we have locked the door.
"Kinky, but still what the fuck are you two doing?" Julie asked.
Well pretty much without thinking, I just got up as I was still completely naked and I kissed her once on the lips.
"We're brother and sister with benefits. We have sex together and can still have relationships with other people," I said.
"And is there any certain reason why you have kept me in the dark about this?" Julie asked.
So I kissed her again on the lips, I pretty much did it because 2 of the 3 people in there really liked it, and I wasn't one of them.
"Well, we really didn't think you'd like it. I mean I'm fucking your boyfriend," I replied.
Then she kissed me once.
"So, you two fuck each other even though you are brother and sister?" Julie asked.
"You just saw his dick inside me, do you need more convincing?" I asked.
"No," Julie replied as she went out to the living room.
Then I just turned around and looked at Don, I wasn't sure what to do honestly. He wasn't sure either, but he wasn't ready to give up on Julie though. So he got up and put on his boxers, then he went out there and found her sitting on the couch I put on my panties and bra and went out there with them. He was talking to her already, but I don;t think it was helping.
"So I come over, we fuck, and then you fuck your sister?" Julie asked.
"Not exactly. We do it whenever we want honestly. He did this for me, not so much for himself," I replied.
"Tiffany, I love you, but let me handle this," Don said.
"OK," I said in a tone.
He knew he should say something about that, but he had to deal with this though. So I kept my mouth shut.
"She was having trouble finding someone that she could stand. All the dates she went on were duds, and this was before you came back into my life. I offered her to be brother and sister with benefits. She first turned it down, she didn't wanna be incestuous. But some time past and she still had the same luck and she came home after another bad date and said 'Let's go' pretty much," Don said.
"And this has been going on for how long now?" Julie asked.
"A few weeks ago, really just before we hooked up again. But we both made it clear we could still have relationships outside of us, and we can stop it whenever we want though," Don replied.
"But she is your sister though, seriously if it happened a few weeks ago and you are still having sex. It wasn't just the heat of the moment, then there is definitely something there Don. I mean really, I haven't been in an incestuous relationship, but now I know this, it makes sense the way both of you look at each other and treat each other. Being close could only cover so much, so I guess really I knew at the back of my mind," Julie said.
"Well, earlier tonight she told me she an get me to do whatever she wants. She was right, but unfortunately you have the same power, so what now?" Don asked.
I don't think that she even knew she wanted truth be told. She said it was kinky, it turned her on at least a little. But if she really did wanna end it with him, I'd be really happy obviously, but on the other hand, Don meant more to me than us continuing our relationship. So if she wanted us to end it, then I was going to, even though I wouldn't like it at all.
"Well did you tell him?" Julie asked.
"About you kissing me and watching me masturbate?" I asked.
"Yes," Julie replied.
"Yes, I told him. I knew he'd find out sooner or later," I said.
Then she got up and came over towards me, she took my hand and brought me up with her.
"You know Don, I can't I completely blame you, I mean Tiffany here is just unbelievably sexy. Perfect sized boobs and she just has the perfect figure. I'm looking at her in just her bra and underwear now and I'm tempted more than ever," Julie said just before she kissed me.
I think we both knew where she going with this, but we let her tell us.
"So how good is the incestuous sex with him Tiffany?" Julie asked.
"Amazing to say the least, do you have a brother?" I asked.
"I do as a matter of fact, would you recommend it?" Julie asked.
"Yes, if he is into it too," I replied.
Then she kissed me again, but for about 10 seconds that time, I knew Don cock had to be as hard as a diamond by then.
"Do you wanna keep being his sister with benefits?" Julie asked.
"Yes, you don't mind," I replied.
"Well, I'll compromise with you two, I'm guessing he wants it to continue as well?" Julie asked.
"Yes," Don replied.
"Well, I'll give this compromise, if you answer this question correctly, fair enough?" Julie asked.
"OK, what's the question?" Don asked.
Then she came over to him and gave him a kiss.
"I knew that tasted familiar. Whose better in bed, me or her?" Julie asked.
"Is the correct answer you?" Don asked.
"Maybe, then again, maybe not," Julie replied.
He thought about it for a minute.
"Sorry Julie, Tiffany is better in bed," Don said.
"Correct," Julie replied.
"What?" Both Don and I asked.
"Well you two have obviously bonded a lot and there is a lot of chemistry there. This what I want," Julie replied as she turned around and looked at me.
She came towards and took my hand.
"I'm obviously attracted to you Tiffany, I don;t know why other than you are just sexy or it's a slight jealousy thing that makes you sexy. I'm not sure, but I wanna have a threesome with you two, right now," Julie said.
"You wanna fuck both of us?" Don asked.
"Just once for now anyway, let me see where it goes," Julie replied as she began undressing.
We weren't sure what the fuck exactly, but if this meant everyone could have the best of both worlds, then we were up for it it seemed.
"Can we talk for a minute first?" I asked.
"Sure but don't get started without me," Julie replied.
So we went into the bedroom to talk.
"Are you alright with this?" Don asked.
"If it'll get her you just let it go and let us be us, then yes, I'll do it. You are more than worth honestly," I replied.
Then he gave me a kiss.
"And are you curious now? I saw you kiss her too," Don said.
"Curious yes, but this still for you though," I replied.
"OK I love you forever," Don said.
"I love you forever more," I replied.
"Remind me to tickle you later," Don said.
"I will," I replied.
Then he went out there and had her come in with us. Truth be told I was nervous, but this was for Don and I. I wanted him to be happy and let's face it, he'd be a lot happier with me in the equation. So they both came in here as Julie was just in her bra and underwear.
"Well you are sexy in your bra and underwear too, I'll give you that," I said.
"Thank you, I'm guessing you are up for this?" Julie asked.
"Yes, because we love each other," I replied.
"Wow, I must say just wow, you two some brother and sister, I've never ever seen siblings this close," Julie said.
Then I kissed her once.
"But I want to know this, are you gonna be good to him?" I asked.
"Yes, I promise, now kiss me again," Julie replied.
Then we began making out passionately for a minute. Don's dick poked out of his boxers a bit.
"Someone is horny," I said.
Then we both looked down at his cock and we both were quite impressed by how big he was. I was also a little disappointed too, though, I mean his cock got that hard for her too? But I got over it. Then Julie got down on her knees and too his cock into her mouth. I think he was trying not to like it though.
"Don't worry sweetheart, I'll still love you after this is over," I whispered in his ear.
Then we gave each other kiss and he whispered in my ear too.
"I love you too sis," Don replied.
"Enjoy it, you like having sex with her," I said.
"OK sis," Don replied just before we made out passionately.
So we were officially having a threesome. I didn't want it, but it would be worth in the end though. He laid back on the bed and I laid down with him. We made out for a minute as Julie kept blowing him. He put his hands on my boobs and gave them a nice squeeze. Julie looked over at us the best she could and saw us.
"Yes make your sister scream," Julie said.
Then I leaned up and took off my bra and underwear as well. Then I had 2 sets of eyes just eyeballing me like hawks. I felt more than a little nervous then.
"What;s wrong sweetie?" Don asked.
"Nothing just a little nervous I guess," I replied.
Julie saw that and felt bad.
"Look, if you are just not OK with this, then forget about, I'll be OK," Julie said.
"No, I wanna do this for you two. If you'd like out relationship better if we do this, then I'll do it," I replied.
"How about this, I wanna try it with you Tiffany, how about if it's just us?" Julie asked.
Then I looked over at Don.
"Do it if you are comfortable sis," Don said.
Well I thought about it and it seemed like something I would wanna do at some point in time It looked like the perfect opportunity had just presented itself.
"Well, can he stay and watch?" I asked.
"I wouldn't have it any other way," Julie replied.
Then Don sat back and watched us. I took off her bra and underwear as well, and as we were both naked, she was on top of me and we were making out. Truth be told I was getting more comfortable with just her for some reason. I don;t know why, but I was fine for the time being even though I had never been with another woman before.
"I'm sorry if you thought I was mad, I'm so not mad now, you have like the best sister on the planet," Julie said.
"Thank you," Both Don and I replied.
Then we began making out once again and we both put our arms around each other really tightly. Don just sat there and played his dick a bit. Of course he was watching two hot ladies making out right in front of him. After about 5 minutes, she broke the kiss.
"You are one sexy lady. I've never done it before, but could I eat you out now Tiffany?" Julie asked.
"Sure," I replied nervously.
"Don't be nervous, I'll be gentle," Julie said.
"Can Don give me a kiss real quick?" I asked.
"Sure," Don replied as he got up.
He came over to us and kissed me. Then for the first time ever I got eaten out by another woman. She started licking my pussy really slowly. It tickled a bit at first, but then I really started to get pleasured.
"Oh yes Julie," I said.
"You like it?" Julie asked.
"Yes, keep going," I replied.
I don't know why, but she was really bringing it out of me. She spread out my pussy lips a bit and I began moaning really loudly. I began getting sweaty already honestly, it was something different for me to experience I guess. I was more than open to it honestly. I put my hands on her head and she tongue deep inside my pussy as far as she could.
"Shit, that's good Julie, you certainly have the woman's touch," I said.
"Sitting right here," Don replied.
"I said 'the woman's touch' Don. You are all man," I said.
Then she began moving her tongue around a but and it just felt amazing. I mean not as good as when Don did it, because he has the brother factor going for him. But she was great to say the least, my pussy was really wet and it was getting wetter by the second. I looked over at her and face was drenched, I couldn't believe how much she was into it. She said she had never been with another woman before, but her pussy licking skills said different honestly. Then I leaned up and put my hands on her head. I looked over at Don and he was still stroking his cock like mad.
"I love you," I said.
"I love you too sis," Don replied.
Julie made me explode everywhere, including her face.
"Damn," Julie said.
"I know, thanks," I replied.
"Anytime," Julie said.
Then Julie climbed up on top of me and we started making out with me once again. It was nice and getting nicer by the minute. I still wasn't sure what was going on with us, were we experimenting or what? I thought that was the most logical, but I still wasn't sure honestly.
"Well, how sexy do you think I'm now?" Julie asked.
"You are probably a 10," I replied.
"Probably a 10?" Julie asked.
"OK you are definitely a 10, Don does go after the 10s, don't you Don?" I asked.
"It's true, I do," Don replied.
"Well, why don't you try it now. Try it once for me and for him," Julie said.
"I'll do my best," I replied.
Then she got on her back and I climbed down towards her pussy. I was very nervous of course, so Don came over to me and gave me a big kiss.
"I think you'll like it sis," Don whispered in my ear.
So I leaned down and began licking Julie's pussy. I had never been with another woman and I gotta say I was liking it so far honestly. It wasn't as hard as I thought it would be. I stuck my tongue deep inside her pussy and made her moan almost immediately. So I knew I was doing something right at least. My face really started to get wet then, all the juices flowing out was nonstop.
I couldn't believe how into it I was getting truth be told. They laid back and made out as well just as we did a few minutes earlier. It was clear that he loved me, but he still really had the hots for her too. So where this going after this was still up in the air though. I spread out her pussy lips as well and stuck my tongue in there as deep as I could get it. I loved it around as well she started screaming.
"Oh shit Tiffany, prove me right, do it," Julie said.
I guess I was the best sister in the world. I was fucking my brother's girlfriend. But unfortunately, she couldn't take it and she exploded all over my face as well. Then I climbed on top of her and we made out for a minute. Then we both looked over at Don and he shot his load on the floor.
"We must have really turned you on bro," I said.
"I know, 2 hot chick fucking, what's not to like?" Don asked.
"I don't know, now get over here already, we need 3 for a threesome," I replied.
