One earlier morning, my step-sister and I decided to go swimming.
Since we didnt have a pool we had to take a bus to get there.
Hailey and I walked over to the school where the bus was waiting to take a group of us to the pool.
The ride wasn’t bad, but the bus was packed. My sister and I just texted our friends to pass the time. When we got there we filed off the bus, I carried the cooler with some pop and sandwiches in it while Hailey carried the backpack with our suits, towels and sunscreen. The resort was pretty crowded but there was three big pools so plenty of room. We found two beach chairs that were free, we laid our stuff down. Hailey headed to the girls locker room to change into her suit and I
headed to the mens. After about 3 hours of swimming, they announced over the loudspeaker that it was time to dry off before the bus arrives. The bus came roughly 20 mins later, we grabbed our stuff and went to it. There was quite a few people in front of us getting on
and we were last.
So my sister and I made our way back there. Three of the last seats were filled up with peoples pool stuff.
I turned to my sister and asked “how you wanna do this cause frankly I don’t wanna hold this big cooler on my lap”.
“I don’t wanna hold this stuff either” she said.
I suggested to her that we could put the stuff on the seat near the window and then she could sit on my lap. I heard the driver say
“please sit, we are going now” We put the stuff on the seat, I then sat down and she threw one leg over me and sat on my lap.
“Hey, didn’t we agree for me to sit on your lap” I said with a giggle. She just gave me an elbow to the chest.
After a few minutes, I began to poke her ribs and she kept squirming. I was going to poke her again but I felt my cock twitch.
Oh god not now...stay down stay down, I kept saying in my head. It was a losing battle, every time the bus hit a bump,
she would come down on my cock.Now it was poking her on her butt cheek. She had to feel it because she kept adjusting herself which made it worse.
She asked me what it was. “Its my cock”. “Oh my god”! “I can’t help it...try to sit still and it may go down”.
She moved again and that made the head of my cock slide between her butt cheeks. “My god it’s at my butthole”!
“Can you move forward”? I asked. “No, my knees are already up against the back of the seat”.
It was very uncomfortable especially because it was being bent. “Stay calm and try to lift up so I can move it” I said.
She put her hands down on both of my legs and pushed up. This gave me just enough room to slide my hand down my shorts and to push
my cock forward. She then sat back down on my lap.
“I can still feel it” she said. “I’m sorry, that’s the best I can do”.
We seemed to be ok but the bumps in the road kept her bouncing on my cock. I tried not to be turned on but it was a losing battle.After a few minutes I began to feel a dampness on the middle of my shaft.
“Was she getting turned on?” I wondered.
The bus suddenly hit a huge pot hole. We flew up and came back down. Now I could feel the warmth of her skin and wetness on my shaft.
My cock grew to its full 7 and a half inches. She started to freak out.
“I can feel your dick on my pussy and I can see it poking my bikini bottoms out between my legs”!
“Calm down, we don’t want anyone seeing us. The velcro on my trunks didn’t stay shut, my dick must’ve came out of my trunks and it went through the
slit in your bikini”. “This is so wrong Isaac”!
“I have an idea...we need to lift you up so I can put my dick between us”. “Ok ok, but hurry”.
She tried to lift herself up but couldn’t get high enough. I told her “I’ll help you”. I could only use one hand to help lift,
the other was going to pull my cock back. “Ok so on three push up”. On three she and I lifted. I couldn’t quite get high enough.I tried to pull my cock back but it was caught it in her bikini. Every time I moved it back and forth, the head would slide between
her lips. “It’s caught in your swimsuit” “Try harder” she moaned.
I couldn’t blame her it did feel nice. I kept moving my cock, she didn’t fight me so I continued. My cock was sliding between her
lips and I could feel her pussy hole. She was so wet and kept letting out slight moans. She dug her nails in my legs.
“You ok sis?” “Uhhuh”
The unexpected happened, the bus hit a pothole. But the unexpected was that, she came right down on my cock and the head was in her.
“Dam Issac!” She cried. “I’m sorry...want me to try and lift you up?” I asked. “Yes”I let go of my cock and placed it on her butt cheek to lift her up better. By the way, her pussy felt great around the head of my cock and her
juices was running down my shaft. I just hoped I didn’t hurt her bad cause she was very tight. As I started to lift, she stopped me.
“No no no please dont take it out” she said.
“Let go, I got ya”.
She placed her arms up on top of the back of the seat in front of us and laid her head down. The bus took another bump and made her
slide down more of my cock. Now my cock was two inches in her.
“Are you ok, do you want me to lift you up?” I asked. She said “no”.
“Are you sure?” “Uhhuh”.She then started to rock on my cock. I couldn’t believe it, she was enjoying it. I know I was, her pussy was so hot, wet and
unbelievably tight.
I eased off from holding her up to the point where I barely was “Are you ok?” “Uhhuh”.
Another bump came and she slide two more inches down. She moaned again. “How much more till you’re all the way in me?”
I was shocked, “a couple more inches”. “Mmmk”.
Suddenly the bus rode over a part in the road that was being worked on. It was so bumpy, it caused her to slide down the rest of my
cock. She let out these tiny moans with each bump the entire way down, it was so hot.
The bus made it to the new road. I pulled her back to my chest, wrapped my arms around her. “Are you ok”?
She moaned “uhhuh...your cock feels so good in me”, she whispered. “Your pussy feels real good too”, i replied.My god did it, she was so hot and wet, and it kept pulsating around my cock. She started to move her hips in circles. We both moaned.
I slid my hand down into her bikini and started to rub her clit.
She moaned “mmm yessss Issac...fasterrrr”.
I continued to rub her clit in circles and began to kiss her neck. She kept moaning till she suddenly stopped and held her breath.
Her pussy got tighter than ever and she started to shake.
“I’m cummmmmming”. As her orgasm subsided, she relaxed a bit.
I whispered in her ear “that was hot”. “Issac...please fuck me”, she moaned quietly.
“Ok sis” I didn’t need to be told twice. I had her to lean forward and put her hands up on the seat in front.
“When I lift, you help too”.I started to lift her by her hips, she pulled herself up and used her legs to push off my thighs. She slid at least six inches up my
cock then back down. She was so tight and wet. We picked up speed. I told her to keep quiet, she was starting moan louder.
She bit the back of the seat. “Does that feel good”? I asked.
She moaned “mmMMmm”! I felt the pressure to start to build in my nuts.
“I’m gonna cum soon”.She then picked up speed and after few strokes up and down, she slammed down on my cock and exploded with an orgasm.
“OOOoooh fuck Issac”! Her pussy was pulsating all around my cock, the feeling was more than I could stand. I came into my sister.“I’m cumming sis”! Squirt after squirt, her pussy kept milking my cock, didn’t think it would stop.
“Mmm Issac, your cum is so hot”. I pulled her to my chest, wrapped my arms around her and kissed her neck.
“That was awesome sis”! “Wait till later big brother”. My cock stayed in her the rest of the way home.
