** step brother

Female teen at the time during covid lockdown after coming from overseas trip we needed to do a mandatory 16days, me and my step brother were put in the same hotel room. After the 10th day he was pacing back and forth angry all the time, i asked him whats wrong and he explained he had not masturbated for over 20 days in total. He was extremely ** and asked me if i could "milk him" i was shocked at first had no idea what he ment by it as i was much younger than him. He asked me stroke him until the white stuff comes out. He said i needed to do it at least 3 times in a row because its built up for a long time and its harmful to his health. I was naive and stupid he showed a video online how its done.
Initially i denied but secretly i watched the ** site he shared and a few hours later i said i will do it but i dont want to see his face, he needs to cover it with a bed sheet which he agreed.
So i started stroking him whilst he laid back on the small couch. Not even 3 mins later it all gushed out everywhere. He kept saying keep going and i kept stroking with ** going all over my fingers and wrists. I actually liked it. He said for second round to go slower so i did.
Now he told me to just put my mouth over the tip for the second part, i dont need to do anything else but stroke and hold it on top. I was reluctant but also curious to see what this stuff tasted like. He had alot of thick ** just under the tip and a small amount still on the actual hole. I was actually wanting to taste the creamy stuff, so i said i will go over the tip now. I opened wide and went straight halfway along the shaft squeezed lips and dragged to the top taking the whole creamy section along with my tongue. I was instaly hooked to the taste but didnt want him to know. It was chemical bitter taste but really strange and nice. I swallowed slowly so he wouldnt know, at the this point he had no idea a buig gulp of ** was pooled there since his face was covered.
So this was round two i kept stroking mouth still over it and he started to shake and ** in my mouth, i instantly swallowed ** like a vacuum. It was more runny and bitter.
He was shocked he asked "did you just swallow?" yeah no problems i said taste not bad but a little bitter.
I asked if he wanted a third try he said no all good. He asked not to tell anyone i said wont.
That same night he wanted to talk about what happened, he was curious if it tasted bad and felt sorry for me. I told him not to worry it tasted "ok" and it was good practice for me when i get a Bf one day.
So from then on after lockdown he would message me once a week usually on a sunday when he had a big load to come into his room and release him. He was already covered when i would walk in and just practise ** and swallow.
This would go on for about 3 years. In that time i think he was also pimping me out to his school mates.
He asked me one day if i wanted to try someone elses **, they would be covered in his room and i would go to work on them ** and swallow. As i got to learn later his friends must of kept their loads for days, they had massive loads i was strugling to get some of them down.
I was sucking about 3 big loads a week and he was having the newest electronic stuff in his room, stuff mum dad would not have money for. So i am guessing he pimped me out.
There was one time when he started dating this girl i could hear him ** her he came into my room afterwards sat down down covered his eyes with a pillow sheet and flopped it out to **. Right after it was inside her with all her juices. I sucked and swallowed but i told him i didnt like that. So thats my confession.
