After Rehearsal

Ok, so I've been dying to tell someone about this since it happened, but due to the nature of the situation, cannot. I'll try and make it short and sweet. So, my sister (26)recently got married. I gained a nice, new BIL(27). I met all of his family a few months ago, and I have to say his Dad..Jack,is so hot. Def eye candy. He's like mid 40's(looks 30's easily) 6 ft. 3ish or something, really good shape, blue eyes that just sparkle at you! He always makes me a wet mess when I'm around him! lol. Although we never say too much about it, I believe he has the same effect on my Mom(40) because I've watched her eyeing him every time we're around them. So, at my sister's rehearsal, everything went well except I decided I wasn't going to spend the entire evening there and was going to get my mom to take me home earlier. Upon hearing this, my sister said Jack, was having to leave early as well and she would see if he would mind taking me home. He said it was no problem I was totally welcome to ride with him. Little did I know JUST how he meant that, but would soon find out! From the minute he said he'd take me, I started fantasizing about him. In the car with him I was so on fire and hoping he would do something. He didn't. He just kept talking and eyeing my legs and short dress. I felt like he liked what he was seeing, and I wanted him to just pull over and take me. He didn't. He waited until we pulled up at my house, wanted to check and make sure it was ok before driving off(which I loved! But, I believe he was also making sure no more family, or anyone was home.) By the time we got back to saying "Bye" he leaned down to hug me. I felt his arm around my lower back, and he pulled me in tight and said"I hope you don't mind me saying this, but there is such a gorgeous girl in your sexy dress!" He immediately added"I could have that backwards, it may be a very sexy girl in a gorgeous dress!" He was still holding me and I could feel myself starting to soak my panties! He asked which it was and I just kissed him...right there. His hands were immediately under my dress exploring. When his fingers made it to my panties, I was right, I was sopping wet! He pulled his fingers out to show me, then quickly stuck them in his mouth and licked them clean(God, I loved that!). I quickly yanked his zipper down and found the most beautiful, big, thick cock I have ever had! I seriously couldn't reach around it. It was so freaking hard, too. There was like an inch or more between my fingers and thumb! He picked me up and carried me into the downstairs den, laid me on the sofa, and literally ate me like no one ever has, EVER! I came the same way...like never before. At least 5 or 6 times. When he spread my legs and entered me, I was already spent. He def stretched me out! It didn't take long before it was feeling so incredible each deep stroke! My clit, was riding his entire length, back and forth. He fucked me into 3 more orgasms and when it was his turn, for some reason(and I had never done this before) I wanted to taste his cum, and feel it pumping into my mouth. And boy, did it. It was a lot! It wasn't near as bad as I'd always imagined cum tasting. Actually, in the moment, I was feeling so slutty, and loving it!! He, was cumming so hard. I wanted to show him I could please him. He just kissed me, and told me I was fucking amazing!( his words and I loved it!) Before I got up, he bent down, kissed and licked my well used pussy, and thanked me for being so yummy and hoped I might want to do this again. He also reminded me that it went without saying"This is our secret, ok?" I easily told him yes on both things. I def wanted more. It was a bit awkward seeing him with family at the wedding. Hoping to have a repeat soon. I noticed my mom checking him out several times again, too. When it dawned on me, how he knew his way around our house so good. He carried me straight to the downstairs sofa. Like he had been there before.Then, it hit me. I bet he had been there before....with my mom. I don't know what to do now. How to find out. It just seems weird now. It's def messed me up wondering now.
