Water fight

One day I was getting home from work in the summer time. It was around 530, when I got there. My girlfriend have left a note on the door , that said," Change your clothes , and get some ammunition because we are hoping to having an old school water fight. I change into some swim ttunks and a tank top. I had an orange thong on that was revealing my bulge. And plus it was my girlfriend favorite thong on me.When I walk outside to the back yard, I saw my girlfriend wearing a two piece bikini. My girlfriend is very thick and curvy, which I love. Her bikini was red, and very revealing. Her boobs and ass barely covered in the bikini.She had three buckets of water balloons already made. She bought 4 new water guns for the water fight. She turned the sprinklers on so we can more wet. We were about to start the water fight, she waved at the neighbors because they were nosy. She asked me, if I was wearing something underneath my trunks.i said yes, then she want me to prove it. I showed a little preview. She said no that's no fair because you are wearing a lot of clothes . She said to strip. I took off my tank.top, so she can my ripped upper body.  Then I took off my shorts,  so she can me in my thong.  I  tossed my trunks at her, and she watch me spinn around, and getting turned on by watching me. I asked her, should i take off my thong so i can be naked. She thought about it, and said no i do ot , when you least expect it.  I just laugh and said ok baby.We started to having fun  chasing each other. When she was getting some water balloons,  i pulled off her bikini top off. She was just wearing her bottoms. Then she was turning on the water hose, when  took off her bottom, and now she is completely naked.  One time i had my back to her, she pull my thong off , and now I was naked,  just like her. We continue to have fun, but my dick became hard because her big tits was bouncing around and plus the adrelinin. After the water fight,  we got in the hot tub. I went in to the kitchen,  to get two glasses and some wine. We drank , watch the sun set and the we started to have sex in the hot tub. After we got out the hot tub, we in the room, to have some more sex.
