Each thrust caused her big ass to roll forward and back. The squishy sound of her pussy was immediate and loud. The white froth of our juices built up...on her pussy and my cock.“TAKE ME, BABY! TAKE YOUR SLUT MOMMY’S PUSSY!”Mom rocked back hard to meet my thrusts. The slap of flesh on flesh resounded through our media room. As mom screamed I felt her pussy clamp down like a vise pushing my dick out of her. I gripped her hips tightly, forcing my way back in.Her arms collapsed and she fell forward,. As I put my purchases down, the assistant glanced not at me but atthe woman behind me. No words were spoken but a non-verbal message passedbetween the two of them and a slight smile appeared on the face of theassistant. I was now feeling very flushed and getting increasing agitatedas the assistant deliberately took as long as possible scanning my items."38C?" she enquired. "You can return it if it doesn't fit." Her eyesflicked again to the girl behind me, her smile returning for a couple. Turns out she wasn't his actual partner but a fuckbuddy and also his neighbor so they had to be careful who saw them together as she was also married! I can't remember if he was as well, I don;t think so. Anyway, he drove to a nice fairly remote house not far from Exeter and we all went inside and headed to the bedroom. She was an attractive lady and he had the air of ex military being much better built than me.For the next couple of hours we enjoyed a very good threesome. We D'ped her, which.
