When Derek came closer Kristina's hand reached out towards his bulging crotch as she rubbed herself but before she could make contact he moved to her side. As his mouth found her ear she tilted her head to the side to give him better access and a long, lewd moan came as he nibbled on her ear. Again she tried to reach for his crotch but he again moved to stand behind her and slid his large hand over her petite breast. A much louder moan sounded from her lips as the hand teased her hard, sensitive nipple. Her nipples had been at least semi-hard since the morning and they were even more sensitive than normal.<br/><br/>Kristina went a little weak at the knees and she leant back into Derek as he held the hand still rubbing her pussy. His kisses and nibbles just made her melt into him so much more. If Derek looked at Kristna's face in one of the many mirrors in the room he would see that she was a very different Kristina than usual. Her face was a mask of lust and arousal. The usual spark in her eyes was gone, replaced by a flame. She squirmed there in pleasure, but part of it was because she was still trying to get her hand on Derek. Turning her head in his direction she whined, "Whatever, just don't stop," and with that, she leaned forward enough to slip her hand between their two bodies and gripped the cock poking into her back. She massaged it there through Derek's pants as her other hand rubbed herself. "There it is," she chuckled as she looked up towards his face.
