Natalie asks with concern what Jelma was doing and she just replied, "Paying you back for your unyielding commitment to me as your sister". Jelma pushed Natalie down on the bed fondled her wetness as she sucked and bit her nipples. Just as she was about to bring Natalie to the brink of explosion, she pulled back and asked Johnny if he would like to taste her while she tasted her sister. He agreed and they formed a train on the bed licking and sucking on each other until Johnny was rock hard again. Now it was Johnny's turn to enter some sweet darkness so Jelma positioned herself on all fours, and allowed Johnny to delve into her hot slippery pussy. As he was pounding into her she laid Natalie onto the bed and began to suck and nibble on her clit until she felt it swell in her mouth. Just as all three were about to have a screaming,simultaneous orgasm another knock came to the door. Cathy called out to Natalie that it was time for her "turn down her sheets"...
