The doctor pummeled with all his strength into Sali....he heard her mewling begs and wonders as she started pick up the pace and start more violent return thrusts which slapped more loudly her delicious buttocks on his thighs. Teacher knew what was the problem.....after all he had got partners before who adapted but the catgirls seem quick to adapt new fetishes. Where as human it takes few sessions to reprogram their bodies, it seems catgirls reprogram near instantly.<br/><br/>The teacher grins, huskily panting and enjoying the tightness of the Sali's cunt while drawing hand to side....and slap hard and firmly on her buttock and he says; "Answer is simple my kitty; you<em>need</em>suffer pain to get off. So we need treat you more roughly with you so you can get off...." The probable reason why Sali got off earlier was because of long anticipation and also along with mild pain from large brick in her cunt and cock ramming her ass as well. So teacher claws Sali's ass hard, leaving red traces on her skin while his other hand on her breast now claws the soft warm titty flesh, pinching and stretching her nipple hard while moving his lips to side of her neck and bite her hard! Hard enough to leave deep red mark in her skin! Give small stimuli's of pain to see is several small stimuli's of roughness to get her off or will she need more extended session of pain to trigger her orgasm.<br/><br/>Also teacher's own pace goes more rough; faster and harder in his thrusts as he mercilessly starts abuse Sali's cunt with his cock in changing the angle bit more tighter in entry.
