Unexpected sex with unknown girl

It was a very hot Saturday and we were planning to go for a nice swim in the near by river . My self Bikey , a 45 years old male with a nice fat Bonner of six inches length and five inches girth along with my another male friend reached the river at about 3 PM . We immediately released ourself from our respective clothes and jumped into the cool water and were enjoying the swim in the nature . Both of us were naked and while being inside the water itself we were playing with our tools . I always enjoy jerking my dick inside the water . It is a different kind of feeling . Looking at me and knowing what I was doing my friend also had an hard on and he too was playing with his cock .
Now like us , other two females also reached the river bank to have a bath and started to get undress . One of them was above fifty years and was not so sexually arousing but another was a sex bomb . She might me on her mid twenties , with a nice and sexy pair of boobs . She was on her kurtha shalwar while the old lady was wearing saree . We watched them from inside the water and being naked and on the condition of jerking seeing a sexy girl was most pleasurable. We increased the speed of our handjob but it was very difficult to eject our scum in water . We were planning to seduce the young girl . So I suddenly stood up from the water showing my ass towards the girl , my friend was to read her expressions. He told me that she was shocked to see a matured man ass and was blushing knowing that a man was bathing inside the river naked while she was just five meters away .
I turned to face the girl now , my tool was pointing towards her inside water which she couldn’t figure out . I was playing with water . Throwing water with both hands towards my friend and he was doing the same to me . My eyes and mind was over the girl who was now opening her clothes . She removed her kurtha and bra but before anyone could see the beautiful melons she covered it with a Peticoat and tied it just above her breasts . She than removed her shalwar and then she removed her red panty too . All the time I was watching her . Her nice smooth white skin was shown . Her peticoat was covering the part above her mid thighs and up to her breast . The main sex spot was not seen but even the remaining body was also enough for me to increase my sexual urge .
Her aunt ( I heard her calling the other lady aunt) was scared to enter the water but she jumped into the water . She came to the water up to her pelvic level and starting playing with cool water . I could she her peticoat floating upon the water level like a umbrella . I knew that she was also naked inside the water as I have watched her remove her cloths . The thought of her nakedness and water touching her cunt was also touching my cock was most arousing . I slowly entered fully including my head inside the water and went towards her . I was a feet away from her and could feel her aroma . I just poked my head out just beside her as if I didn’t knew her presence there . She was aware of my nakedness as I was about her . Her peticoat was still floating . I wanted to seduce her . I looked at her aunt and she was busy washing her clothes so pointing to a black object floating and coming towards me I Suddenly screamed and stood up to show my hard cock to her .
I acted to be afraid of some water inscect . She laughed at me and when she saw my long thick cock pointing towards her face she was red . I also acted like I realized what had happened and hide my cock under the water and said sorry to her . She just blushed . I told her that she was also naked under water and I know it . She was red with shyness . I slowly went near her and try to touch her .
She told me that her aunt might see , oh my god if her aunt couldn’t see than she was ready to play sex with me . I went to her back and hide myself under water and reached her . I slowly touched her body and was able to reach her thighs . Those were the best and smooth . She was surprised . I took my head out and asked her to cooperate with me . She giggled and slap me slowly on my right cheek .
Meanwhile I signaled my friend to go home leaving my clothes on the beaches and I could see him leaving with a wish of best luck in his face .
I again went under water and touch her navel with my finger . She shivered a bit and hold my hand and pushed it to the southern reason of her body . I took it towards her bushes and reached her pussy cracks . She was sticky wet there . I touch her clit and enter my finger and played with her pussy for a while . She removed my hands from there . I took my head out of water and sat behind her . I caught her left boobs with my left hand and with right I caught her right hand and placed it upon my standing cock . She played with it , stroking it to and fro and tickle my balls . She was an expert . I asked her do she like ice cream . She answered that after bath she will stay to wash clothes and send her aunt home and then only she will taste the ice cream . So we were just waiting her aunt to leave .
Finishing her job aunt told her to come soon and left . I hug her form the back and started kissing her neck . My cock was already hard and was touching her ass crack . I turned her towards me and gave her a lip kiss which instantly turned into a tongue kiss . Our tongue were exploring each other Tasting and playing with our mixed saliva. I was also pressing her boobs and playing with the erect nipples . We both sat under water and were playing with each other’s sex organ with our hands . I was fingering her cunt while she was playing with my cock . I stood up with my erect and throbbing dick Pointing her , she stood on knees above the river sand and started tasting the ice cream . She was an expert ice cream sucker , she gave me a deep throat blowjob . I was about to come so told her to stop . I took her to the beach and lay her on the warm sand and started licking her cute pussy . I spread her cunt lips and insert my tongue to play her g spot . She was in heaven , I could hear her moan now . She begged me to insert my dick inside her pussy and fuck her . I put both her legs upon my shoulder and put my dick in her pussy in one go . She screamed with pleasure and I started fucking her in a great speed . My balls were smashing her ass cheeks while my whole long fat cock was doing in and out on her cunt . It was nearly ten minutes of ramming her cunt and I could find my blood in it’s full pressure and I released my scum all over her boobs and belly , some drop even reached her mouth which she greedily ate with the help of her finger . I could at the same time see her twist and stretch her body . She reach her orgasm same time When I ejaculated .
