I joined a school trip to with 3 other friends to Japan for a immersion programme. One of the nights, we had to sleep in the traditional japanese hotels called the ryokan. Of course, 2 had to share one room and I shared it with Jo, one of my best friends.
After putting down our baggage etc, I suggested to him , 'Hey, Jo, want to go to the japanese bath?'
He was a bit reluctant and said, 'but in those baths we have to be totally naked.'
I smiled and replied, ' Come on, What you have, I will also have.'
Jo paused for a while, grinned and agreed.
When we reached the bath, I stripped first followed by Jo. I could see that he, like me, already had some pubic hair at the base of our penis.
Then we entered the bath. After we had sat, down, we looked at each other's genitals.
Then, Jo remarked,'Ja, you have a big dick!'
I replied, 'Ha! proud to have one too!'
Jo laughed and asked, 'Do you masturbate?'
On that question, his dick started to become erect.
I replied, 'Of course! All boys do don't they?' and on seeing his erecting dick, mine grew hard too.
Seeing that both of us were horny, Jo said, 'Hey let's masturbate together and we will drink each other's cum'
As horny as I was, I replied,' Ok!'
Then, we proceeded to rub our large adolescent penises until Jo panted, 'I'm cumming, I'm cumming'.
I then put my mouth at his dick and gleefully slurped every single spurt of white juice that came out.
I did the same later and Jo drank my juice.
After that, we washed ourselves and left the bath. Nobody knows what we did at that time
