For the girl this was the first contact in her life with a male sexual organ. Aigul instinctively clenched and recoiled. Mikhail Mikhalych, with a quiet chuckle, seized her hips and pulled her towards himself. He slightly stretched the halves of Aigul's bottom and began the struggle with her tight sphincter. He took his cock in his hand and by thrusts forced a path for himself. His cock was short but fairly thick. Each successive thrust allowed the penis to penetrate half a centimetre deeper. Aigul wept from the tearing pain and humiliation. The lecturer was not concerned by her tears. What had Eva said? One must relax? How was one supposed to relax when it hurt so much? Nevertheless Aigul, fighting panic, tried as best she could. It was very difficult. For the cock was penetrating deeper and deeper, as if increasing in size. It seemed to Aigul that she was about to be torn apart.
