Myself aged 19 wearing a black knee length pvc mac and martin,,the 50 year old guy,,walked in the park,his arm around my shoulder pulling me close to him.I was so innocent,thinking he was just being friendly I put my arm around his waist as we walked,he asked me what I would like to do,again not knowing really what he meant I replied anything.He looked at me,smiled,turned towards me and kissed me on the lips,mmm he said you have soft lips,i blushed he started kissing me again,really snogging me,it felt so good I responded,we necked really hard and long,it was so exciting I came in my pants,shaking I pulled away from him,did you like that he asked,yes I said I did,but ive cum in my pants,,he laughed,your the first to do that he said,you must of loved it. We talked for a while,i told him about myself,he told me he was gay and liked young men,asked me if I wanted to be his girl,im not a girl I said,no but you can act like one he replied.we walked on arm in arm and came to a bench overlooking the dockyard,he told me to sit on the bench which I did,he stood in front of me pulled down his zip took out his cock which was much bigger than mine,i stared at it,you can feel it he said,no one will know,no one can see,it was very dark by now.Nervously I felt his cock,it felt really hot,he held my hand on his cock,making me wank him,it was good and he was soon rock hard,he then pushed my head down onto his cock,without thinking I started to kiss it,he pushed against my mouth making me open for him,slowly he pushed into my mouth more and more,i gagged,he stopped,suck he said suck me,i did.I sucked him whilst he moved in and out,his cock going deeper into my mouth,he held my head until he started throbbing in my mouth as he stated to cum,i tasted him as he filled my mouth with his juices,he pulled out and shot more come over my face and mac.i was exhausted but really high with excitement,he smiled and said Iknew you could be my girl,i laughed,yes I said I am.
