Had sex with my best friend of 15 years and discovered something crazy (F20)

My best friend, for privacy reasons I wont say his name and will refer to him as Eppy. (Eppy's a cute name I like that) Eppy and I have been best friends for, basically our whole lives, I don't really talk about him on reddit and I asked permission for this post a while back and he said yes but never got round to it, Eppy is the complete opposite of me, he's shy, nervy, but goddamnit is he adorable (that last one is not the opposite of me 😜) where as I am a loud, ADHD, mad girl who hooks up with guys frequently (mainly at my Uni so don't get any ideas 😝), but Eppy is different, he didnt want to be with me and wanted to well, hook up with me, and it was difficult for him, and i understand entirely, some people function very different to me and other boys but he nervously asked me last year I should say, or the year before, I think i was 18, but he nervously asked me if he could; in his words "go and perhaps get coffee and try the boink." The boink, hes so cute 😍, obviously the boink meaning he wanted to fuck me, and of course I said yes, it was a little nerve-racking coz i had known him for so long but I developed a little crush, though, I have a girlfriend and hes just my friend, but my bestest one and he feels the same. So we went to get Starbucks, chatted about life and then he took me back to his place to get frisky, he was really really nervous I could tell so I keeped it chill and lowkey for him, but what im about to say, is a reminder to all boys that no matter what your dick size is, you can act however you want, if you have something you're self-conscious about, you can express it and be tough if you want to be tough, if you have a biggen, you dont have to act tough, be who you are at heart, all of you. Because when we were stripping, my heart racing coz i was so excited, 10 maybe even 10.5 fucking inches boi-oi-oing up from his waist band and I just stared in awe and excitement for a moment, I knew this boy for all my life basically, (I mean this respectfully) never did I think that he could hold such a monster, considering how sweet he was, anyways, we had nice, not even rough just easy and slow sensual sex, obviously got more intense the closer we got to orgasm, coz of course It would but it was really passionate and sweet and that 10 inches inside me, considering how small my pussy is Im surprised I didnt split open, but it was awesome, and he dumped a load right into a condom in me, and part of me wishes it wasnt in a condom coz it was deffo a big warm one, tho it doesnt matter coz my kinky ass asked if I could drink it and he let me 😜. But god damnit man! I love this guy, and he still continues to be the sweet best friend I know and love. Packing a smooth and fit big one down there, and he actually asked me to post this actually, coz hes kept it to himself basically all his life only letting me and some of his super duper trusting friends know, and hes ready for his legacy to be shared, he wouldn't do what I do, hook up with people he's not too familiar with and go bonkers, but hes definitely starting to be more independent, and considering hes 20, im proud of him, he was such a sweetheart growing up, and as he steps into the real world, Eppy knows, Bridget (me) will always guide him, and if he ever wants another round, I'm all in 😏.
