Sucking the tip several times, she strokes my shaft before taking it a bit deeper in her mouth. Unable to deep throat, she still manages to get a good...portion of my cock in and does a fantastic job at it. I push her down on the bed and spin her on her back. I grab her tits as I tease her mouth with my cock. She quickly pulls her tits out of her bra, exposing her hard nipples, as she reaches to put her lips back around my head. Loving the feeling, I grab her tits and play with her nipples. I heard my step-daughter say, "Oh. Wow. That's like intense. That is so dirty," as I finished cumming inside her, and lay there.When I was done, I pulled out slowly, Kristina's little vagina filled with my sperm, and leaned back against the couch, spent, soft, and worn out. Kristina sat up, pulled the towel over to her, and started wiping between her legs. And then my step-daughter said something I never would have expected:"Now I got to watch, can you do that to me too so I can know what it's. I contorted, twisted and rotated. I began reacting to her body's reactions and did more of what I thought she liked most.We made love for almost an hour (true). I was so nervous and anxious. I honestly couldn't cum even if someone offered me a million to do it. So, I just kept going...and going...and going. She moaned and shook several times. I remember how she'd whimper before each climax and I really liked how I could feel her opening tighten around my penis each time she came. It worked for. One minute she was exclaiming her cumming and the dog’s and the next it was silent, silent except for the grunts. It was like she was suddenly holding her breath as the orgasm crashed over her, but the grunts and convulsing from the orgasm forced the expulsion of air from her lungs.Then, she just dropped to the matted floor. Her chest and face pressed into the floor, her ass still sticking up, tied to the dog. Then the dog turned, before I could even think of giving the option for considering,.
