Hala and Gwendolen

Despite one being a pale skinned ginger and the other a dusky brunette, the two students entering your room for the last tutorial of the day are physically more alike than you would have expected. Both slightly shorter than average, with exaggerated hourglass figures emphasized by their cowl-necked décolletages, both of which reveal considerable expanses of well-whipped titflesh. Their faces are similarly round, with high cheekbones, delicate lips, perfectly straight noses and heavy-lidded eyes which give every impression that their owners didn't get much sleep last night. In fact, Gwendolen can't quite smother a yawn as she takes her place at your table.

"Late night?" you enquire, pointedly.

"Yes, Professor." It's Hala who answers. "We were practising our interpersonal skills last night and some stockbrokers invited us to a party, which ended up going on all night, but it's nothing to worry about."

"Mm," Gwendolen joins in. "When we were pledging for the sorority we sometimes had to go three or four days without sleep, so we're used to it."
