F18 Fucked my dads best friend

Apparently i have a crush on my dads best friend (he is his co-worker as well). One night he visited our home late night with my dad after work they came together after a loooong meeting and he stays about 45 minutes more far than we do from dads work so we offered him to sleep with us instead of leaving to his home late that night as he was tired from work etc. In the opposite side of my room there is the guest room where people visiting us can sleep. Usually i masturbate before sleep so i have it easier and relief the stress of the day but because im usually alone upstairs in my mind it got totally wiped that we had my dads friend that night too so my door was a bit open like usual (mostly i leave it open for my cat to enter) and he was taking a peak without me realising but when i did i called him to come in my room anyways as i was super horny and in the same time he was my crush for many years, grabbed him by his pants and shushed him so he doesnt make any noise, he was stroking it while watching me before so he was already hard af. i told him to remove his pants and i sat so hard in his D that i couldnt control myself anymore but he didnt want me to stop as well and wanted me to go in doggy as well so I did...thats how the night finished and promised to each other to never speak about this and act normal. He really keeped his promise and I really fullfilled my fantasy, wrong or not i like to fullfill my fantasies no matter what
