It was 2am and 18 year old Ethan was asleep in bed at home where he still lives with his parents. It was midnight and a quite warm night, so he was naked under the bedsheet with the window partially open.
He has a completely hairless, smooth, slim and slender body and a small useless micro penis, which is just as well because whilst he is outwardly quite straight acting, he is in fact bi-curious, submissive and in some ways quite feminine in nature, which doesn't go unnoticed by some people that know him.
In the next bedroom were his parents, both sound asleep, and across the hall in the spare room were his aunt and uncle - 43 year old Tracey, and, 48 year old, balding, hairy, pot bellied, dad-bod Chris. They were staying over for a few days while they were having some structural work done at their own house.
Tracey was fast asleep, while Chris, albeit very tired, was laying there beside her still awake as he planned.
Chris had a huge hard on as he laid there slowly jerking himself off. He too was naked because of the uncomfortably warm night.
Noticing it was 2:am, he carefully got out of bed, making sure not to wake Tracey. In the dark he reached for his bag and took out a tube of lube; he applied some to his hard 10 inch cock before wiping his hands on a small cloth he had in there.
He then crept out of the the bedroom, his erect lubed cock swaying side-to-side with the movement of his walk as he went down the hall quietly past Ethan's parents door to Ethan's room
Once inside Ethan's room he slowly closed the door behind him. It was dark but Ethan's naked body, now uncovered due to him kicking his sheet away in his sleep was partially bathed in blue moonlight. Chris walked over to the bed; his cock strutting as he stood right over his sleeping beauty nephew.
Ethan was on his back with his legs partially open; Chris carefully clambered onto the bed and was kneeling in front of Ethan between his partially parted legs. Chris then leaned over him and placed his hands either side of Ethan's head, and then gently used his left knee push Ethan's leg wider, then did the same with right. Ethan then began to stir a little.
Chris then laid himself on top of Ethan, his hard cock squashed in between Ethan's flat hairless stomach and his hairy gut.
While Ethan was still asleep, Chris was gently kissing his face and neck to gently coax him awake. Ethan then did gradually come round, but went into a panic.
"What the ff..wha?!!" Ethan exclaimed.
"Shhhhhh, it's ok, its uncle Chris." He said in a hushed calming voice.
Ethan momentarily fell back into a semi-conscious sleepy state as Chris continued to kiss him.
Chris then began trying to position Ethan's limp, sleeping body into a missionary position, which was proving more difficult than he imagined.
Ethan then woke, wondering what the hell was going on.
"Spread your legs for me." Chris whispered.
Too tired to resist or question, a sleepy Ethan just instinctively obeyed the instruction, opening himself wide open, presenting himself.
In between Ethan's legs, Chris put the tip of his hard lubed cock to Ethan's moonlit butt hole.
