First same sex experience

Growing up was a difficult time sexually for me, Most of my friends at school were female and the boys I hung around with were all straight...so opportunities were pretty much none existent.
I'd had the odd kiss and fumble with girls but wasn't really into it and most people thought I was gay anyway!
I wasn't open about the way I was but looked very young and feminine and to make matters worse I was extremely shy.
Anyhow the group I hung around with were all into drinking and smoking weed. We were 13 at the time, Not sure if this is normal behaviour but it certainly was where we grew up!
We used to visit an older man on our estate who sold weed amongst other things, He'd often let us smoke and drink in his flat and he was pretty hot too ;) He always wore shorts and never had a top on, I'd often to look at his muscled physique and fantasize about sucking his cock but never in a million years thought it would happen.
He was the rough and ready type and often expressed hatred towards 'queers & faggots' but was always nice to me, Giving me free weed and drinks.
One evening our group were there for a while, As we got up to leave he asking me if I wanted to hang back for a while...I was shocked and scared at the offer but just couldn't say no. As soon as my friends had left the flat I heard him lock the door and my heart started to race......I just sat there terrified of him, Imagining the worst possible scenario!!
He came back into the room with drinks , sat next to me and asked me if I'd ever be fucked! I quickly made up a story of having sex with a girl but he replied ' No, have you ever BEEN fucked' I mumbled a 'no' . I'll never forget his response 'Get undressed then boy!' I sat there sipping my drink wondering what the fuck was going on when he shouts ' FUCKING UNDRESSED NOW!'
I did exactly as he said, thinking to myself I really don't want to be in this situation and that it was a sick joke being played at my expense....Until he pulled his shorts down revealing a thick erect cock! I thought my heart was going to jump out of chest at this point, Mixed emotions of terror and excitement, I just reached for his cock and started to suck it, It felt different to how i'd imagined it to be but I started to enjoy myself sucking and licking the tip.
He disappeared into the kitchen for a second then returned rubbing something over his hard cock 'Get on the sofa, Arse in the air' he says whilst walking towards me, I did. The next thing I know I've got fingers shoved inside me with an unbearable stinging sensation! I realise then he's using washing up liquid for lube! He then enters me, forcing his cock deeper and deeper with each thrust, The pain was so intense I let out a scream..He forces a hand over my mouth and tells me to 'Shut the fuck up' and carries on pounding me faster and deeper, I can barely breathe and try to block out the burning pain of his cock inside me when he thrusts hard into me and groans, I feel his cock pulsing as he cums into me and I let out a sigh of relief.
He quickly withdraws and hurries off to the bathroom while im sat on the sofa with his cum leaking out of me, On his return he calmly tells me 'If you say anything about this I'll kill you' and asks me to leave.

I returned to his place many times over the next couple of years to get free weed and a quick fuck :)
