Then the unmistakable sounds of her orgasm as it went on and on. Bill was quieter but I had no trouble telling from his gasps that he was flooding Susan's tight cunt with his thick, silky cum. He must have collapsed on top of her for I could hear his breathing as he recovered. Susan is so wonderful at this time... she. ”I continued to move my finger from her vagina hole into her ass as I licked her clitoris. Her legs began shaking and she pulled at and pinched her nipples moaning and begging me to go faster. Her hips rose off the blanket and she threw her head back. “Cummmming ... don’t stop ... awwww.” She stopped breathing for a minute as the first major wave of her orgasm hit her. :Ok ... stop ... stop now.” She breathed.

My other sons bad name rise day by day. I can understand you can’t wait that long. I can say your choice is good.

She approached him and was talking, suddenly she leaned forward and whispered into his ear, he smiled at her and put his clip board down, and turning to face her she kissed him.Her arm touched his as they kissed, it didn’t bother him either as he turned to face her, she turned him back so he had his back to the units as they kissed. They snogged for quite some time until Donna whispered something to him as her lips slid onto his neck, and then his hand moved onto her breast, as they snogged.
