“A kajira must study her partner.” The teacher said in an even and slow tone to ensure her young students heard the point of today’s lesson. “You must be first observant. Look at your partner.” She strode to her teaching partner with the sensual feline moves befitting a teacher of the sexual arts. Her partner was a better-than-typical specimen of the kajiru, the male descendant of sex slaves. He was tall, handsome, and tone. The teacher placed her hand on his muscled chest and look back at her class of girls. “Notice the muscles, not just for their appeal but for what they tell you. Is he tensed or relaxed? Is he flexing?” She moves his fingers over his cheek. “Is his jaw clenched? Every male is a little different but often a clenched jaw will let you know when the beast may be drawing near the surface and he needs release.” Her fingers following the furrows of his sculpted body down to his crotch, letting her finger tips lightly play in curls his pubic hair. This caused his cock to immediately rise. “Then there are the lower regions.” Her finger trailed along the length of his now erect penis. “Is he hard, soft? Are his legs or hip muscles flexing?” She now made eye contact with her students whose attention flicked back and forth between their teacher and her subject’s deliciously hard cock. “Learn your partner well girls, whether long term or for a night. Learn his tells. Then you will know how best to please him and receive his satisfying reward.” With that she gracefully moved to her knees as if swinging from his cock and in one deft move engulfed him in her mouth. Everyone let out a moan in relief, in ecstasy, and in need.
