He cums inside Katie

At first Katie worked Andrew's dick into and out of herself slowly, but that changed when she began to pick up the pace. Andrew was in awe of the incredible pleasure being given to him by his friend's tight pussy. He reveled in the feeling of the vice grip it seemed to have upon his member. He closed his eyes and let the feeling just take him away. The only thing he wished is that he could be the one in control. He wanted to be fucking her.

It struck him that he was thinking of his oldest friend in such a dirty manner. He loved the idea of his cock taking her virginity, that it was his dick defiling her. She was willingly fucking herself, shoving him deep into her most intimate place. The idea was too much for Andrew. Only a few minutes into the sensation, he felt his dick twitching, readying for its explosive release. A dozen strokes later, he simply couldn't hold back any further.

Through gritted teeth Andrew groaned once again. He felt his testicles clench. His cock throbbed, spewing his virile baby batter deep into his childhood friend's pussy. At no point did Katie stop pushing and pulling his dick through herself. Andrew felt her already damp hole become sloppily wet as his cum mixed with hers. About half a minute later, as Andrew's penis began to deflate, he felt himself being pushed deeply into Katie, her cunt tightening around his softening member in pulse after pulse of what had to be her own orgasm.
