fingers trickled up my belly , dipped into my navel and continued upwards , a slow journey under my br**sts and to my areolas , and then ... my knees buckled as he pinched my nipple , sending heat lightning zapping through my body , and his other hand was curving around my hip to cup one buttock , and all this while his lips were on my skin , touching my throat and my shoulder and my chest and cheek , and now my lips .
