My cock pulsed at least five times as each time it shot a blast of cum into her unprotected womb. My legs went weak and I just held myself deep in her...for several seconds before pulling out. I looked at my cock as I pulled it out. It was starting to wilt. It was covered in a mixture of my cum, her cum and her virginal blood. She had bled quite a lot. One of her friends spun me ninety degrees. I could see that she was a big girl. She had to be five inches and weigh nearly twice what the young. “Well thanks to my sister it is,” David replied. They began making a little more as he had his entire cock inside her. I saw her boobs a little squished, even though they were only B-cup boobs. Then they stopped making out for a minute and they put heir foreheads together and while they had their eyes closed though. They were both breathing steadily and I guess just in the moment. “I love you so much sis, it's indescribable how much I love you Tonya, you are the best sister on the planet in. ", I moaned out. She started to bounce playfully on my cock, smiling coyly. It felt so damn good, almost as if my dick had melted like butter into her warm cavity. I grabbed her waist and started to thrust forcefully inside her. "Jooohn!", She screamed out. "Fuck! Please, don't stop!" I hadn't planned on it. "Daddy! It feel so good!", she cried out. At this point I was doing most of the work, but I didn't mind at all. "Good, baby.", I moaned. She had collapsed on top of me and I could feel her. There is an obvious tension about you.We're out on the town playing out a little mystery orgasm game. It's become one of our favorite pastimes. It started out with a simple remote-controlled vibrator in your panties. I enjoyed teasing you in public, making you squirm a little. We eventually made a game out of it. We call it “Three No’s”. The game got its name because you're allowed to tell me 'no' three times. This is not the same as our safe word. That is a hard, fast rule that will always be.
