Cathy found out that her husband was very right, the kids were more than willing and became active participants instantly. She learnt that David had been fantasizing about fucking her for a long time, which she found to be most flattering and Molly wanted to fuck both her dad and brother. But what she found to be most exciting was Molly also wanted to fuck her for a long time. So, the first extra-marital cock that Cathy got fucked by since her marriage to Kevin 20 years ago, and first time in her life she ever tasted a pussy, both belonged to her own flesh and blood, her twin kids.
Over last six months their relationship had evolved. They became more creative, active and satisfied lovers. The kids were simply non-stop fucking machines. Their parents were also rejuvenated by the affair and had been trying hard to keep up. Within the group slight preferences developed. It was apparent that Cathy loved to fuck her son David more than her husband and Kevin loved to fuck her daughter more than his wife. It was their preferences and they knew there was no jealousy involved. However, mother and daughter had developed a very special relationship within the group also. They were both crazy about eating each other pussies, specially their cum filled holes. They loved to lick all the cums that Kevin or David had deposited inside their recently fucked pussies.
After securely fastening her strap-on over her pussy Cathy joined her family. David blew a wolf whistle looking at his naked mother sporting a large rubber dick.
“Here comes the lady with the monster cock.” Molly cheerfully commented.
Cathy picked up the oil bottle and poured a generous amount onto her fake dick. It started glistening immediately. She went around and placed herself in front of David’s behind. She spread his compact and tight ass cheek and pour oil into his tiny hole. She stick her tongue deep inside her son’s rectum and spread oil all around his tight ass muscles.
“Oh, mom, it feels so good.” David cooed in approval.
Wait honey, it would get better, she thought.
She stood up and placed her rubber cock at her son’s anus. She took Molly’s legs that was around David and wrapped around her. She pushed. Her rubber dick head parted David’s ass hole and slowly went into his slippery tunnel. It burnt his anus as the rubber dick made its progress. However, He felt very comfortable when his mother’s big breasts smashed into his back. Cathy extended her arms and grabbed her husband’s behind. She began to fuck her son’s ass.
Kevin and Cathy had their kids uniquely sandwiched between them in this special position. While Kevin was fucking his daughter’s ass with his cock at one end, his wife was fucking her son’s ass with her fake cock from the other end and in between them David had his cock buried all the way into his sister’s pussy.
“Mom, I am cumming.” David cried out. He had been fucking his sister for over 20 minutes now, he could not hold any longer..
“Okay baby, let mummy help….” Cathy started pumping his ass fast and furiously.
