I paused a moment; pulled my cock almost out and then slowly pushed it in all the way until my balls were pressed against her butt cheeks. I smiled when I heard her let out couple a soft sigh. I started a slow steady in and out movement. Katie pushed back to meet my thrusts as we fell into a synchronized rhythm. Katie’s breathing increased as she reached between her legs and started to furiously rub her clit. I started to pick up my pace when I felt the muscles in her ass start to squeeze my cock. In a very short instance I felt my orgasm start to build and Katie was breathing harder and starting to squeal public and shriek. Our mutual orgasms hit at the same time. Katie was shuddering all over and I felt my legs going weak. “Ahhhhaaaaa… Graaaaa…Ughhhh!” We both screamed out at the same time and then fell forward on the bed. My cock slipped from her cum filled ass. We both lay there exhausted and gasping for our next breath of air. Reggie praised us both, telling us we had just cleared a major hurdle in our sex education. We had both brought each other to a satisfying sexual climax. I was proud of myself. I was confident I could successfully bring Katie many more fulfilling orgasms, even without having a cock as large as Reggie’s.“Okay…I have one more thing I want to show you and then I am going to fuck get out of here and let the two of you have fun with what you have learned over the last few days,” Reggie said. Katie and I both look puzzled. “What else could you possibly show us? I think you have shown us everything in the Kama Sutra,” I remarked. “Have either of you ever heard of ‘DP’; double penetration?” Reggie asked. We both shook their heads NO. “Well, well…then you are both in for a real outdoor treat. Katie, get over here and suck Ted’s cock until it springs back to life again.” He ordered. Katie deep throated my cock a couple of time before it came back harder than ever. Reggie lay on his back in the middle of the bed and told Katie to straddle him and take his cock into her pussy. She had a questioning amateur look, but obeyed. Once she was in place, and his big cock was deep in her pussy; Reggie pulled her forward placing her head on his chest. after a few strokes i could see lots of cum flowing out and she was moaning. She came to the door and we pulled her in and closed the door quick. Toby shouted, gripping Rachel's nipple between his thumb and forefinger. “Such a loving boy!” she moaned. “No, mother, I am outdoor not coming home amateur right this minute,” we heard, “James needs me right now . . . I whimpered. You've endured so much." What excited me even more was the feeling of power I could prevent it, but she couldn’t public . I knew in conscience ,I should bang on the window or do something to couple stop it, but I didn’t want to stop it . I wanted it to happen. Hearing her sister moan she pushed forward and worked her way fuck up to her clit. You won't have as far to fall.” Her fingers twitched as she swayed.
