How I discover my Bisexuality

I was 18 when I meet my girlfriend who was also 18 she was a very pretty girl , slim , great body and sexy as hell . The day I meet her I was crazy about her .
By the time we were 19/
sex was a common occurrence. We were at it when ever we could , but the big problem was getting our hands in a condom as we did not wanted pregnancies so it was mostly 69 er . until one of her girlfriends suggested to her we should try doing it in her arse .
We thought a bit about it, but one day we were horny and lucky that her mum and dad were not at home. So she suggested it to do it in her arse … I liked the idea so in order not to hurt her I used conditioner .
Spread t on my cock and her arse and slowly penetrated her . WOW she enjoyed and so did I , so from then on it was either 69 er , a traditional fuck when we had a condom , if not …it was fucking her arse and licking her sweet pussy .
I never had imagined have any sexual thing with guys , I just thought girl was the only way to go .
At school they guys always used to tease me and tell me I had a nice arse when we were in the showers after the sport sessions .
Our group was Mathew, Frank , Bob and Charles , we did everything together , but I never even looked at the while in the shower as , they were always telling me I had a nice arse I just ignore them the school had a communal shower , with 15 cubicles and no doors on them.
A wide-open corridor led to the communal change room .
Every Friday was a sport day and two of the students were rostered to put the equipment away after sports . I did it often as I did not mind and as I liked sports, I was usually the last to go back into the showers .
It was the last four weeks of school and we had the usual sport day . Mathew stayed back to help up putting the equipment away
So everyone left and it was just me and Mathew storing all the equipment , when we completed the job just went into the showers
I just did my usual thing , stripped nude and went in to the shower , as I was doing this, I hear some moaning noises from Mathew , I turned around and see he hi pulling himself …
At that time I saw him having a very hard cock in his hand , looking at me …the same time he cum squirting a huge load out of his erected cock .
I asked “ what are you doing ?” he responded “ I am just looking at your sweet arse , if you don’t let me fuck you , at least I can pull my self-looking at it “
I just laughed
Next week the same he just waited till I was in the shower and pulled him self and once again I saw his cum blowing out … it was a lot
I found my self thinking about it in bed and I was getting horny about it so I wondered how it would feel since my girlfriend enjoyed it so much . so I got a thick candle and rubbed shampoo conditioner all around it then put some if the conditioner in my arse and inserted my finger deep inside .
Then I got the candle and carefully inserted into my virgin arse …it felt great so I just motion it fucking myself as I masturbated GOD di I like it until I cum .
For the week this was a regular thing before going to sleep .
The Friday came along and even I was curious if I should give in and let him fuck me, I went as usual into the shower . Mathew and I were alone again .
This time I just looked at him directly as he pulled him self . his cock was very hard and nice.
He got closer to me and touched my arse but I moved his hand away . Once again, he cum but this time some of it end up in my side .
I moved away from him and just went into the shower .
That night I was hornier than ever and could not stop thinking about his cum on my body that day . Now I di want hm to fuck me
Last day of school and again we were by ourselves in the showers this time he was asking me to let him feel my arse as he pulled him self .
I was now also horny and my cock was hard , he had seen that , I guess that is why e was asking
I just looked at him took the conditioner bottle and poured a full load into me hand then looking at his hard cock just rubbed it all over my arse then just turned toward the shower .
A few seconds after I could feel his hard cock close to me arse crack and felt his hands around it .I was decided so I just touched his cock and bend a little forward he just said “you have no idea how long I have been dreaming this “
Carefully he guided his cock and placed the tip of his great cock just in my arse hole then he slowly pushed it in , I was delighted it felt much nicer than the candle . Sadly after just two pumps I felt his cock throbbing and the warm of his cum inside .
I just looked at him and said “ is that all ?” sorry he replied next time I will be longer
I just said “just keep this between us .
It was the last school days so after that week went by and al I did was fuck me girlfriend and often fuck myself with the candle and after rub y cum in my arse thinking it was his
About 3 weeks after he called me and told me that his parents holidays home was empty for the weekend and invited me to go with him … he said that he had a delay gel so he could last longer if I was to let him fuck me again .
I agreed to go .
We arrived just after mid-day we had lunch and sat with a bottle of whiskey having a few shots
He then went in and had a shower an come-out nude and with a hard cock . I did the same .
As
I came out of the bathroom he was placing a gel in his hard cock , walked toward me and guided me to the bedroom, we were a bit drunk after all the drinks .
He stood in front of me grabbed my arse and kissed me …I just responded to his kiss . he pushed me towards the bed and got me to laid on my back. He then lifted and opened my legs wide open and inserted his beautiful hard cock in arse .
I was so horny by now that he could do what ever he wanted . I was now truly being fucked and I felt like a real slut .
The gel worked and he pumped my arse , kissed me for over 20 minutes until I felt his hot delicious hot cum filling my arse …I could not avoid it and blew me cum between his body and mine .
That night we went to bed together and he just made me his bitch for the night fucked me from the back and jut left his cock deep in my arse as we sleep .
I knew now I was to enjoy his cock any time
Four weeks later he called me and invited me again for the long weekend at the holiday house
This time unbeknown to me invited Bob another school friend Bob was the guy with the biggest cock in the class who also used to tell he would like to fuck me and he did many times over that long weekend along with Mathew but that long weekend is a whole new story
