Such a tight hole…

Few weeks ago, my gf little brother saw me naked aftee shower… And I could saw his curiosity when he saw my dick… Since then he alway was hitting on me, making jokes, like if his sister don't want to I could fuck him…
One day my we went out for some drinks and got little wasted… Back at my places, we joked around, about me taking his v-card, since he only hat given bj till now. He got real horny and I could saw that he had a boner. I joked and said: “wanna try it?” first he hesitate a few seconds but went down on his knee and pulled my cock out… Slowly sucking it gentle…it felt so could I just couldn't stop… I slowly shove my cock down his throat. After a while he wanted me to fuck him, so I tossed him on the sofa, gentle pushing my cock against his hole, I could feel how it gentle slides in… I looked at him, and saw that he has a little pain so I carefully stretched him until I could going… Onelce he was stretched and the pain stopped… He couldn't stop moaning and he really seemed to enjoy it… I turned him into doggy and gave him slow but deep backshots… After a while I was ready to cum and wanted to pull out but he didn't let me… So I had to finish inside… After we where done he looked at me and said: ” now I know why my sister is so happy with me… And I'm always welcome in his hole”
