Naked for childhood oil massage

[Freesub]

One of my friends told me this story.
When he was 13 he went to his grandmother and aunt's homes (next door to each other) for vacations. He had a lot of fun there, but when it came time to bathe, grandma insisted on giving him an oil massage first.

He was quite embarrassed as it had been over an year since she saw him naked, but he managed to convince himself it was just grandma and got naked while she started doing it.
Of course the most embarassing part was when the oil had to be applied to his dick and balls, but he dealt with it and managed.

However, just then , the door opened and his aunt came in, much to his chagrin and embarrassment. He tried to cover up with his hands but was forced not to by grandma and stood there shamefully as his aunt took an eyeful of his goods and soon after, she grabbed his dick and balls on the pretext that they weren't oiled properly, and teased him a bunch as she applied oil again to his privates, purely for her own fun.

The worst was yet to come, when in walked his aunt's daughter, his cousin, and she started laughing her head off as the poor guy was stuck standing naked, unable to hide his nudity from her. He pleaded with them but they told him he was just a child , and he didn't need to feel shy.

After half an hour or this embarassment, he was finally able.to bathe and get dressed, but they continued to tease him for the rest of the trip, reminding him that they had seen all his junk, and since he has nothing in his pants which they haven't seen, they can freely pantse him anytime at home(full pantsings, pants and undies).

He was glad when he could finally go back home.
