she felt it resonating through her in the ravaging depth of his kiss , in the way he set her on fire when he sucked on her breasts , her back arching to the intoxicating heat of his mouth , her flesh burning under his mouth as he moved it slowly , erotically , down her body , her stomach tightening with almost painful tension when he reached the apex of her thighs , parting her legs , stroking the soft hidden folds of her sex , kissing her there , licking her most sensitive place with delicate flicks of his tongue , an exquisite torture that she could hardly bear but did n't want stopped .
