I have to admit I was smitten with her and we got along really well. ‘How's about we head to the park this morning?’ I suggested ‘Can we go to t...e zoo? I've never been’ she asked, smiling back. There are a lot of places she hasn't been thanks to her parent’s fear of her condition being somehow discovered. Sure I said kissing her head. As I got up for my shower, more often than not she joined me.We got to the zoo just as it opened, it was a glorious day but the zoo was empty, even some of the. There were in a bar. Full of men. And it was dark.The man got Mark a drink and said: "You just stand there. I'll be watching." Watching for what?" You'll see. Just go with anything. It'll please daddy." The man then gave Mark a deep, long kiss and, again, Mark's mind went blank.So, Mark just stood dumbly with a drink in his hand. The moments ticked by, and he kept glancing at the older man in the corner. Well, so much for my resolve.Then it happened.He felt a hand on his ass. The hand then. When I opened my mouth he forcefully stuffed his cum, blood and shit covered prick in as far as I could take it. I gagged and tried to spit him out but he held my head so I could not pull off. He dug his fingers into my hair and used his hands to make my head go back and forth. He was fucking himself with my mouth. Finally he released me, pushed me down onto the bed and pressed his body against mine. He told me that I had done well and that it would not be long before I enjoyed and looked. One hand moved up to grab her tit while the other moved around to her ass as we kissed some more. She slid her hands around my butt and pulled my rock hard cock into her. That was it, we were going to fuck. One of the great things about this woman was her proclivity for oral sex. For as long as we'd know each other she always loved sucking my cock and she always did a great job no matter where we were, if it was a quickie or a long event or 'road head' on the way to dinner - she'd often suck.
