We all decided to take a mini vacation and head up to the family cabin. My two sisters and I needed some time alone after our parents died a few months ago in an accident.
My twin sisters, Gloria and Diane, both 20 and I just had to get away and since I am the older brother at 22, I convinced them that we needed to get away and they agreed.
We made plans to drive up the following weekend. The weather was supposed to be nice and warm, great for swimming in the lake, something we all liked to do.
Friday morning rolled around and we packed the SUV and headed to the cabin. On the way up we sang songs, told jokes and had a really nice trip.
The ride was more than two hours but it flew by and before we knew it, we pulled up to our weekend getaway.
We all helped unloading the SUV and put things away and cleaned up the place. Before we knew it, it was lunch time.
I prepared the grill and we all enjoyed hot dogs and burgers and nice cold beers.
After we finished, I asked the girls if they wanted to go for a swim and they said they would like that.
They went into their bedroom and changed into their bikinis and I went to change into my suit.
I searched my clothes but couldn't find my suit. Then I remembered where it was, on the top of my dresser back home...I forgot to pack it...ugh.
I called out to the girls and told them I forgot my suit. They peeked out of their room and Gloria said, "Well, big brother, what are you going to do now?
I thought about it for a second and replied, "I guess I am going to go skinny dipping."
They laughed and then they ran out of the cabin and down to the lake. I followed and when I got there, they were already in the water. I quickly shed my clothes and jumped in naked.
I swam over to them and when I got close to them, they started grabbing at me and pushing me under the water. I could feel their hands all over my cock, balls and ass as I tried to get away from their attack. All the time they were laughing.
Somehow, I finally escaped their attack and managed to get close enough to them where I could grab their bikini tops and pulled them off.
As they were flustered, I managed to go under the water and and I untied their bottoms and took them off and held them up for them to see. I then swam to shore, leaving them naked in the lake.
I ran up to the cabin with my sisters chasing after me, yelling and screaming. Their tits bouncing as they ran. I managed to get in the cabin and locked them out, all the time laughing.
Diane said she had to pee so I told her to pee. She looked at me, turned away and I could see pee streaming out of her.
After a few minutes, I let them in. They immediately tackled me and knocked me down as I was still holding their bikinis.
They started slapping me, all the time our naked bodies pressed against each other. One sister held me down while the other one grabbed my cock.
I was laughing so hard but the one holding my cock started jerking my shaft.
I yelled out, "Hey sis, what the hell are you doing?"
She yelled out, "Getting even big brother."
As I couldn't move, she kept jerking my now hard cock. I told her to stop or she was going to make me cum.
They laughed as she continued jerking me off. Then I said, "I am going to cum you little bitch." As soon as I said that, I shot streams of cum into the air as they finally released their hold on me.
They looked at me and Gloria said, "Now, we are even."
I laid on the floor, cum still dribbling from my cock as they walked away.
I got cleaned up with a hot shower and the girls followed, then we all sat around having some wine and snacks, laughing at our earlier antics.
Diane was laughing when she said, "Sorry about what we did but you had it coming." Then Gloria laughed and said, "Well, I don't know about you brother, but I enjoyed jerking you off. I didn't know you had such a nice cock or I would have done it sooner."
I looked at them, smiled and said, "Well, I enjoyed seeing you girls in all your beauty. I never realized how beautiful you both are. By the way, I enjoyed you jerking me off. You could do that anytime and more. I wouldn't object."
Diane replied, "So, our big brother wants his sisters to play with him. What do think about that Gloria? We have a perv as a brother."
We went back and forth enjoying each other's comments and it felt good to laugh again.
We had a nice dinner and relaxed with more wine until it was time for bed. I went to my room and they went to theirs.
In the middle of the night I woke up with a hard cock and decided on a little revenge. I slipped into their bedroom as they slept. I stood over them and started jerking off. When I was ready to cum, I shot my cum onto their lips and face and quickly left.
Well, about an hour later I heard screaming coming from their room. I was hysterical laughing when they barged in, my cum still on their lips and face.
Gloria started yelling, "You fucking pervert. You came on our lips and I licked your cum, you fuck."
Diane interjected and said, "We'll get you for this. If I were you, I would sleep with one eye open." Then they left.
When I woke up in the morning, I did feel bad at what I did. I started making breakfast and when they came in, I apologized and asked their forgiveness.
They looked at me with doubt in their eyes and reluctantly accepted my apology. I made them a great breakfast and all seemed right with the world, so I thought.
After breakfast, the girls said they wanted to go swimming. I agreed to join them. Diane then said, "You know, we had fun yesterday, let's all go skinny dipping."
I thought about it and figured why not...nothing wrong with being naked with two beautiful women, even if they were my sisters.
"Ok, I'm in. Let's go." I said.
We all undressed and headed to the lake. The water felt nice on our naked bodies. I kidded them that their nipples seemed to enjoy the water as they were hard and erect.
We all swam near each other and on more than one occasion, they felt my cock and balls so much so, that my cock was nice and hard for them to see.
Gloria smiled and said, "Diane, it looks like our brother likes what he sees. Do you think we should help him out?"
Diane responded, "You know Gloria, I wouldn't mind taking care of his problem, if he asks for our help."
I smiled and said, "Yeah, like either one of you would do that for me...yeah, right."
Then Diane swam over to me, slipped her head under the water and wrapped her mouth around my cock and started massaging my shaft with her tongue.
I let out a yell and up popped Diane's head. She smiled and asked if there was a problem.
I looked at her and said, "No, there isn't a problem but if we are going to do this let's go back to the cabin and do it right."
We all got out if the water and headed back to the cabin.
As soon as we got inside, Diane took me to their bedroom. I sat on the edge and Diane knelt in front of me and started sucking my cock. Gloria came over and started kissing me.
As I was getting my cock sucked, I started sucking Gloria's nipples. In no time at all, I told them I was ready to cum. Just as I was at that point, Diane stopped, got up looked at me and said, "You can finish what you started big brother," and left the room with me sitting with my cock ready to explode.
As they left, I heard them laughing.
I got up, still naked and went to them and I smiled and said, "Ok ladies, you win. I won't do any more jokes on you, I promise."
We all laughed and hugged with our naked bodies pressed together. Diane said, "Come on, let's have some wine and get drunk and fool around."
Gloria and I laughed, looked at each other and shook our heads and we both said, "OK."
For the rest of the afternoon, we drank wine, had snacks and enjoyed the sight of each other's nakedness.
Practically the whole time, my cock was hard and I could see wetness on their thighs.
I don't know why, but I said without thinking, "You know ladies, if I weren't your brother, I would fuck you both."
Diane looked at Gloria and said, "Well, why should that stop you?"
Gloria continued, "If we knew our big brother had a cock that big, it wouldn't make any difference who he was."
Then, I decided to take a chance. I got up, walked over to them, sat in the middle and started kissing one, then the other. As we exchanged sensuous kisses, their hands wrapped around my cock and balls.
It didn't take us long before the three of us were in heat. Diane said, "Let's go into the big bedroom."
We got up and went in and got on the bed. We were all over each other and it wasn't long before Diane's mouth was on my cock. Suddenly, Gloria's smooth pussy in front of my mouth and I started lapping up her juices and sucking her clit. I even managed to slip a few fingers in her cunt and started finger fucking her.
My cock was ready to explode and suddenly, cum shot out of my cock filling Diane's mouth. I watched as she swallowed every drop.
