"Would you want to sleep with Kim?" The question rang in Mark's brain as he stood in the doorway. The other question in his mind was: "What would you do if you came back and caught me and Kim having sex?" Mark's wife Carol had asked both just a week ago. At the time Mark had laughed and joked that he would join in. But now his mind reeled. He clung to the door of the bedroom looking at the sight before him.
On the bed laid on top of each other were Carol and Kim. They were laid in the 69 position and were licking and fingering each other's cunts. Mark stared in a mix of shock and horror. When Carol had asked the questions the week before Mark had assumed she was joking. The two of them had been married for just over a year now, and Carol knew of his fantasy about finding two women together and joining in. She also knew that Mark liked Kim. Carol had known Kim for two years; she was her best friend from work. Kim had started straight from school and had just turned eighteen. Carol was a few years older, and Mark was older still by a nearly twelve years.
Now Mark was the first to admit he did like Kim. She was tall and very pretty. With long dark hair, a figure to die for and legs that went up to heaven. But she was no comparison to Carol. Carol was the love of his life and so sexy it hurt. She had long hair that went from brown to auburn depending on how the light hit it. Her curvy figure drove Mark wild, he loved to suck on her breasts and feel her body next to him when they fucked.
Now he could see Carol's sexy firm ass laid over Kim's pretty face. Kim's mouth was latched onto Carol's cunt licking hard. From the gasps he could hear his wife making he knew she was enjoying Kim's licking. Mark watch as Kim flicked her tongue up towards Carol's clit and slid two fingers into her cunt. Carol gasped hard and arched her back pushing her cunt down onto Kim. Who seemed happy to bury her face deep into the offered flesh.
As Mark watched the display he realised he was getting turned on. His cock was starting to push out of his trousers. The sight of his wife ad her friend licking and fingering each other was so erotic it over rode the shock he had been feeling. He knew from the way Carol was hissing and rocking that she was near to cumming. Quickly Mark undressed dropping his clothes on the floor all the time watching the display in front of him. It seemed that so far neither of the two women had noticed him.
He walked towards the bed quietly waiting for his chance to join in. Kim gave a sharp cry and collapsed shuddering in an obvious orgasm. Mark saw his chance. He climbed onto the bed and quickly slid his cock into Carol's now available cunt. She gave a sharp gasp and looked back at him.
"Oh god Mark," she gasped as he began to fuck her. He slid in and out with the long deep thrusts he knew she loved. Beneath him he felt Kim running her finger up to rub it against Carol's clit. Mark could tell how close Carol was to cumming and he began to thrust harder into her. She gasped and moaned hard, breathing deeply. Very quickly she rushed towards her orgasm. Mark felt her cunt tighten around his cock and she gave a sharp gasp as the orgasm burst inside her. Mark was so turned on he was nearly cumming himself. But he had just enough time to react. He pulled out of Carol and bent down to push his cock into Kim's mouth. As soon as her lips closed around him he came. Pumping cum into her mouth. She swallowed hard. The three of them rolled off each other onto the bed. It was a few minutes before any of them could speak. It was Mark who spoke first.
"How long have you two been fucking each other then?" Carol smiled at him.
