One day my family all got together for a summer bbq. We do this often around our family. This year things got interesting. On the Friday night everyone started to head over to our house for the weekend. First to arrive was my uncle Tom and his family. My cousin Sam and aunt Beth. Sam was a hot girl she is 19 5'9 size 3 with 36 DD. She was wearing a short blue skirt and tight white tank top without a bra. I dress the same but with a black mini skirt. I am 20 5'8 size 3 and 32C. I have 4 siblings My bro Ted 18 not too bad looking skinny. My younger sis amber 19 5'6 size 4 and 34 B. Older sis Tami 22 5'5 and 36 DD. And my oldest sis Cindy 24 5'7 and 34 C.
My cousin Sam and I went out into the backyard where my dad and my brother had built a tree house a few years back. She climbed up first. I got a clear view up her skirt and saw she was not wearing any panties. This did not surprise me since I was not as well. As I was climbing up I saw my uncle Tom was walking thru the back yard at the same time and noticed him looking up my skirt. I took a little longer to climb. Once we were up we started to talk. We talked about girl stuff, boy and stuff. Sam is also Bi and been trying to get me started. She slowly started to spread her legs and gave me a clear view of her pussy. I started to get wet just looking at Sam's pussy. I could not hold my self back any longer. I moved over to where Sam was sitting.
"what are you doing Abby?"
"You will see." I said while smiling.
I lowered myself to her perfectly shaven pussy and started to lick around the lips. Then licked the clit. This caused Sam to start moaning. I kept up my lick while I started to finger her pussy with 2 finger. By this time Sam was laying down and my other hand played with her breast under her shirt. "uh god I am going to cum." She said and let out a load and long moan. While I licked up the rest of her juices.
"Oh my god that was amazing where did you learn how to do that?" All I could do was smile. Then my mom called us in for dinner.
Sam and I went down and to the dining room. My uncle Tom was sitting at one end and asked me to sit next to him. So I did.
Dinner had some good food. At our house after we finished eating, we all sit around and talk for a while after. That's when Uncle Tom placed his right hand on my thigh. I did not think anything of it and he kept talking to my dad. Then he slowly moved his hand closer to my pussy. I remember that when I was going to the tree house he saw up my skirt so he knew I was not wearing any panties. His hand reached my pussy and started to rub it. I was still wet from before dinner fun with Sam. He slowly started to slip his index finger in. It was all I could do not to moan. He started to pick up the pace and really get me off. I was holding my moans back and turning red. He kept going faster and faster. I started to cum and clench down on his finger. I burred my face into my napkin trying not to show what was going on. After I came he slid his finger out and kept on talking to my family. I was spent now. I asked to be excused and went upstairs.
I went in to my room and just flopped on the bed. After a few minutes Sam came into my room. We started to talk again and I remembered that I wanted to show her my new cheerleading uniform. I took off my skirt and tossed on my bed. Then went for my cheer skirt. Sam asked if she could try on my skirt. I told her it was ok. Sam said that she like the skirt and wanted to try on some of my other clothes. I told her that there are more on the other side of my bed between the bed and wall. I went into my closet and she jumped on the bed. I was inside my closet when I heard someone walk in. It was uncle Tom. He could not see me in the closet but I could see out threw the slits in the closet door. I saw Sam bent over on the bed fully exposed. It's then I realized that she was still wearing the skirt that I was. Since my bed was on a twin at the time Sam's ass was close to the edge. Uncle Tom pulled out his already hard 10" cock and rammed it in Sam's pussy thinking it was me. I was watching all this happen. Him slamming his cock in and out. Sam took it and buried her head in the bed. I reached under my cheer skirt and started to play with myself while my Uncle fucks his hot daughter thinking it was me. My cousin and uncle was really into it and after a few more thrusts my Uncle moaned and came inside his daughter. Sam just collapsed. After a few minutes of just sitting there my Uncles cock popped out of Sam's pussy followed by a river of cum. Sam turned over and opened her eyes. She could not believe her dad just fucked her.
"Oh shit Sam. I thought you were Abby. I am so sorry" He said
"I'm not. That was great." She replied
Sam sat up and grabbed her dads semi erect cock and sucked it clean. Then tucked it back in to his pants. He left the room and went back down stairs. I finally came out of the closet and sat down on the bed next to Sam.
"Wow, that was amazing." She said.
