As I stood inside I watched Tim moving this plank of wood into position, moving about stretching and bending, I noted his skin between the top of his shorts and the bottom of his tank top, skin was of the light colour with little hair. I was getting a little excited watching him trying to fit the plank at the end of the bench. He asked for my help which I gladly gave while allowing myself to rub up against his body. It crossed my mind that he might suspect my motives, but he did not to say or seem to show it. With the job finished he turned around and faced me as I quickly put one foot on the new seat to hide my bulge.
Tim indicated he needed a hammer that's in the draw of the bench, leaning over opening the draw getting the hammer. Has he hammered the plank of wood making it fixed to the shed I noticed in the part opened draw a poro book and a tube of KY jelly. He wanted to know why I was laughing so I showed him the porn book. He was quick to say the shed gives him privacy from his younger sister who is always sneaking around and with a smirk on his face added the jelly smoothes things along. He picked up the part used tube of jell placed it on the narrow table under the small window and leaned forward putting his elbows on the table and his head in his hands and proceeded to stare out of the window as if looking out for his sister. I stood behind him looking down at is girly shaped arse and hips. I had the hardest cock I have known for a very long time. I was in a quandary, shall I stand back and make some excuse to leave or what???. Without any more thought I leaned forward allowing my hardness to touch between the cheeks of Tim's arse. With my hands at my side I waited some 30 seconds waiting for a sign from him, it felt like 30 minutes, and then he wiggled his arse a little.
I was now convinced he was 'up for it'. I slid my hands up his thighs and moved to the front of his shorts quickly undoing the top button and sliding the zip down, his shorts fell to the floor and he quickly kicked them off and opened his legs more cocking his arse up showing his puckered anus. I looked down at his anus and I had this urge to drop to my knees and give him a tongue lashing, but I did not want to risk this moment in time and break the 'spell'. I slid my shorts and with it underwear down below my knees, I looked up and Tim who still had his head in his hands looking out of the window, I reached for the KY jelly tube that was near his right elbow quickly un-screwing the top and applying a generous amount with some nervousness onto my cock, then wiping my hands on a near by cloth. I held Tim's hip with my left hand and with my right I worked the head of my cock up and down his arse cheeks until I felt his anus, then I pushed, he resisted I noticed his head drop onto his arms. Worried he might panic I moved my hands so as my thumbs were either side of his anus then I pulled him open.
It worked, I slid in and Tim gave an 'mmfffff' noise as I sank all the way in and could feel my hairs on his cheeks. I slid my hand up under his top and griped his shoulders and with three quick strokes I came with such intensity I have never had before today. I dropped my head onto his back and was completely out of breath with my legs trembling. I leaned back still holding his shoulder with one hand, leaning to the right I grabbed his cock with my right hand pulling it to one side so I could see most of his cock and stroked it about six times then he shot three ropes of cum' two landing on the floor and one onto the table top. I could feel all three of his shots as his anus contracted around my cock. Tim's head was laying on his side looking back at me, and not looking out of the window. I suddenly became frightened of being caught, I withdrew my cock pulling up my shorts and telling Tim that its time I got back home. We both dressed putting our clothes in some order, Tim asked if I would fit an internal lock on the door so he can keep some privacy.
I said "yes get the lock and I will fit it."
As I left the shed the world seemed different, that's because it was. As I walked up the garden path towards my home I felt as if a million accusing eyes were watching me and any moment now my world would come crashing down, the shame, wife leaving me, the kids shunning me. I walked into the home and the wife greeted me with a kiss asking if I sorted Tim's problem out, I gave a little smirk saying yes and went up for a shower.
