"Well, I only have the five hundred, unless you're ok with that. You'd only get two hundred and fifty each if I fail," I smiled apologetically.They lo...ked at each other and moved off to whisper a bit so I couldn't hear.Another guy asked the hot Nubian beauty to dance, and she accepted graciously, as I had seen her do since I walked in. As they took the dance floor, Sam and Jim returned."Ok, Mark. We'll put our five hundred each against your five hundred. The bet is now whoever walks out with. It was Beth's turn to start. She got on the sofa and staddled me withher head facing my feet. She had a short dress on and I could see her black lacy underwear. I moaned as her soft moist mouth engulfed the whole of my cock. Beth sucked me off like an expert, swallowing my whole length thenpopping the whole thing out of her mouth before taking it back in again. As she sucked my dick I moved my hands up under her skirt and pulled her panties to the side, so I could get a look at her pussy.. Rubbed Meg's clit as i licked her lips. Just then the other girls came into the room and joined us. I used my spare hands to finger them. Just then Meg came all over my face. I did not know she was a squirter. And then her and Alexis switched places. I started eating out Alexis and god Meg was tight after about 3 minutes of her riding me i came all over her pussy. After that Meg and Alexis laid next to me and rested there heads on my chest."that was amazing" Meg said"Alexis your a lucky girl". Grandad was gently stroking his cock and he nodded for me to join Nan on the sofa and asked where Sara was.I informed him that she was upstairs satisfying Dad, Grandad said he`d go up and check on them, but I said I`d love for them both to go up and I`d see Sara`s reaction to seeing her Grandparents half-naked. Nan and Grandad laughed and agreed.We all stood behind the door just out of sight, although to be honest the last thing Dad and Sara were thinking of is who`s behind the door. Even.
