special needs students first time part three

I am watching the most sexy 18 year old boy,who has special needs,have his swimming lesson,which he has every week,I have all the other mums and dads watching they children have they swimming lesson,and they are totally unaware that i am looking at my hot and very sexy lover,whose body always gets me rock hard,even when he is fully clothed too.
The teacher is getting them to do different things in the water from going to bottom to collect a black brick,to swimming lengths or widths,which means i get to see my lover in all different positions,i wish i could get my cock out and have a wank looking at him do the different positions as i think i would cum loads of times,after he has climbed out the pool at the end of his lesson,he kisses hand the blows it up to me and i send him one back too,
As he goes to the changing rooms to get changed,i gather my bits up and go down the stairs to meet him in the reception area,when he come out he come to me and kisses me on the cheek like you do to your dad,and i did the same to him too,i said why dont we put your bits in the car then go for a walk in the park,so he said he was thinking the same thing,
After we had put his swim bag in the boot of the car and locked it,we started to walk to the park,i put my arm around him and pulled him into my side as we walked along,when we got to the lake,he turned to me and put his lips on my lips and started to kiss me passionately,with our tongues exploring each other mouths and our hand going up and down each others backs too.
After we had finished kissing each other,we carried on walking until we got to the swings and slides,the boy climbed the stairs to top of the slide before coming whizzing down the slide,when he got to bottom,he looked around and saw that the park was deserted,so he grabbed my hand and led me to another area of the park,where he got down on his knees and unbuttoned my trousers and pulled my boxers down to reveal,my very hard cock,which he started to lick and suck,he made sure his tongue reached all the areas of my cock,so no area was covered by his tongue including my balls,which are still covered in hair,as thats how he likes them,his mouth was going up and down on my shaft,which was sending a lovely feeling through my body,especially when i felt my cock start to grow more as it was getting closer to letting it load go into his mouth,after a few minutes more,my cock started to pump my cum deep into his mouth and i was moaning too,after my cock had gone soft and fell out,he pulled my boxers back up followed by my trousers and did the button up too.
As we walked back to the car,we both said that is the beginning of our outside fun,as the special needs boy had left school for the last time today,
