My hot step sister

I am 16 and my step sister is 11 we were at the pool on our apartment the other day and she started to go underwater and feeling my dick i kind of just blew it off the first couple of times but she was really started to get me horny my older brother and my younger step brother were swimming with us so i tried to not let them see what was going on between me and her underwater so i went to the bathroom inside the little pool house outside of the pool to jack off i was in their jerking and my step sister walks in and stares at me jerking i didnt try to hide or anything because it was obvious she wanted to fuck me i had always had a thing for her she lived with her dad half the time and my step mom the other half so when she wasnt at the house i would always find her panties and sniff them or jack off with them anyways back to the story so i was in the pool house jerking off when she walked in and after staring at me for a while as i stroked my dick she walked over and took it in her hand i am 6 inch hard and she just got a feel for it i knew she had no sexual experience so i took her hand and helped her jerk me for a minute but then remembered my brother or step brother or anybody for that matter could walk in so i took her into a toilet stall and started kissing her and quickly removed her small pink bikini top revealing her tiny boobs not even a cup just like little bumps and puffy little nipples i sucked on them for a couple minutes before removing her pink bottoms then i stood her up on the toilet and starting licking on her little pussy her pussy had like maybe 10 small hairs on it and was like a half dollar in size it tasted so good it was running little squirts of precum out of it and i was so turned on by this i picked her up and lowered her onto my dick i was standing up fucking her she was so tight but i did it so fast i had no trouble getting inside she let out a yelp then a loud moan and i started bouncing her up and down on my dick so hard and she was moaning so loud i had to start kissing her to quite the moans i came fairly quick knowing my brother would come looking for me soon i came all inside her and her pussy was dripping with my cum i kept on fucking her for about 3 minutes until she started to tremble and let out a small stream of cum we put our suits on and i told her to wait a couple minutes after me until she came back to the pool so they wouldnt think anything of it i hope she isnt pregnant! THE END
