He shifted his weight a little and slapped one of her breasts after Laura tried to envelop him.  "Now now, little Pet . . .," Eric chided.  Then ,belying his words, he rested all his weight on his arms and her pelvis.  Slowly, his head dipped until his tongue met the tip of one nipple.  Teasingly, Eric licked around the areola, just getting the peak damp and erect.  It took some self-control, but he slid his hips back and forth, causing the underside of his long shaft to glide between Laura's nether lips.  As his organ picked up some of her juices, the head brushed against her nub with each stroke.
