I finally had her boobs and nipples in my mouth. Her ass was nice and round just like boobs. I fingered her pussy and rubbed her clit. Pam started moa...ing. I started kissing her upper body. Pam asked me to fuck her as she did not have sex for months.She stood up and her dress fell down. She was wearing thongs. I pushed them on one side and checked out her extremely clean pussy.I pulled her closer kissed her pussy, pulled her thongs down and started fingering her pussy. Pam was moaning a lot,. I shot my load all over the bed, as he pounded my ass and pulled my cock. I never saw so much cum spill from my cock before.He then pulled out and he too put his cock in my mouth, he fucked me for a few seconds and then filled my mouth.He fell to the bed too, but as he did the first guy got up to go to the toilet.When he came out I was fully dressed."You leaving?" He asked"Yes I am" Where did you come from, are you a friend of his?" He asked pointing to the sleeping tanned man"No I don't know. Let’s see if you can cream me as much.”As I pounded her puss, trying to get traction in the slippery stuff my mind was going wild and I said out loud, “I wish I’d been there to see this get delivered!”She grinned, “That can be arranged.

No hesitation.“You get more and more turned on every time you do something for him.”My sister nodded, fast and furious.“Whenever he innocently asks you for something, you do it immediately.”Nod. I hadn’t been sure how well she’d take that one, but it was clear.
