she knew how she must look to him , held in his power upside down like that , half-fainting , wanting and inviting anything he 'd do to her , lying in a pool of her hair , her breasts almost spilling from her bra under the pull of gravity , her stretch pants bunched midway down her thighs , her light purple panties stained by the darkness of her desire for him , the legs he held trying as hard as they could to pull him down , bring him between them .
