Fun times!

Sarah gasped and bucked her hips a little, biting her lip with a moan. Tom became to nibble at her clit, feeling it get warmer as the blood began to flow into it. He kissed it again and found that it was already big enough to poke out of the clitoral hood. He smiled and licked it, sucking playfully as she gasped and thrashed.

Sarah was in getting more turned on by the second, her whole body was shaking and her clit was throbbing with more pleasure than she had ever felt.

Tom continued nibbling and teasing. Now he introduced his fingers, spreading her pussy lips and starting to penetrate her dripping vagina. Her clit continued to grow. It was now big enough for him to suck it into his mouth and tease it with his tongue. Sarah screamed, gripping the bed as she thrust her hips, the clit growing faster with each thrust. Tom felt his own boner so hard that it was hurting. He slipped his hands down to unfasten his pants and found that her cock was now big enough for him to suck properly. He started bobbing his head as he sucked. A big dose of precum came from her cock head inside his mouth. Tom smiled and started deep-throating her ever-growing cock.

Sarah was beyond aroused. Her body was on fire. Whatever Tom was doing down there had her more sexually excited than she had ever been. She twisted her nipples and felt her clit grow more, it was like a constant edging arousal that continued to grow. She screamed again, gripping the bed.

Tom's cock was dripping precum. Even his nipples were hard. He pulled his wife's cock out of his mouth and looked at it. It was already 15 cm long and getting bigger. He licked it from base to tip and Sarah gasped, bucking her hips again. He giggled and continued kissing, licking and nibbling. His own arousal was almost unbearable. Her cock now leaked a constant stream of precum down it's side. He used it to jack her off, slipping his other hand down to penetrate her pussy. She screamed again, feeling a burst of growth. Tom moaned, standing slightly, slipping his cock against her pussy and beginning to play with it, while jacking her growing dick. After a little play, de began to slip it in, each inch of penetration equalled almost an inch of growth until she reach full mast at 35 cm. He thrust inside her. Her horse cock head began to mushroom out. He thrust harder and faster. Her medial ring stood out, her soda-straw urethra grew proud at the tip of her beastial member. He kissed her cock because it was close to his face as he began to thrust faster and faster, jacking her lovely penis.

Suddenly, her gasping stopped and she sat up slightly, eyes wide. He felt her cock harden even more and her cock head widen, great blobs of precum were coming out of the tip now. He thrust harder, rubbing her cock in it's own lube. She whined a high-pitched note and hoarsely shouted his name. Tom put his mouth over her cock head and waited, suckling and playing at it's surface with his tongue.

She hit her orgasm. It rocked her world. She could feel her clit squirting, pulsing, driving her over the edge. She sat up and grabbed Tom's head, pressing him down as he swallowed her cum. It was too much. It came out his nose, he pulled back, gasping and watching the semen dripping down her shaft and smiled.

Sarah was looking at the appendage between her legs, shaking a little. Tom smiled a kissed the head again, slurping some of her cum. She moaned and a great big blob of cum oozed out of her urethra again. He looked at his lovely wife with the great big horse cock and sighed happily.

Things were going to be different from now on. But what next?
