Losing Vcard At 12 To Cousin

Me and my cousin were always close and we always had sleepovers together. When I lost my virginity to her we were sleeping in her room. I had already hit puberty while my cousin still looked young and was really tiny compared to me. I had already started masturbating and I got horny for basically everything. So when my cousin started straddling me as a joke, I went rock hard immediately. She noticed it and smiled at me, asking if I was hard. I tried downplaying it and saying "It's always like that" or "It's nothing," even though she clearly knew what it was. She had seen me naked before and knew about sex. She got down and yanked my shorts off, revealing the biggest boner I ever had. She gasped at asked if she could touch it. I knew it was wrong but she was too cute for me to care at the time. She started giving me a handjob and I stroked her hair. It was so much better than my own hand. I became way too horny and I needed her mouth on it, so I told her to open wide and I pressed her head onto my dick. She gagged on it and went up and down until she said she wanted me inside her. Of course I immediately stripped her and brought her into a doggystyle position. I stuck my dick in her, but it didn't fit. I had to press hard for it to go in, and it broke her hymen. I could tell it hurt a bit for her, but I didn't care. I kept going until I finished in her, and we promptly fell asleep. We continued to fuck daily after this, and I still pound her every time I see her.
