After our divorce I was dating another woman and still was having sex with my ex wife Karen. Karen is attractive and has 34C breasts. We had sex a couple times while I was still dating this new woman.
One day Karen said to me, "I want you to come to me house this Friday night because I have a surprise for you."
She wouldn't tell me anything so I got there at 7pm and she met me at the door naked. Karen proceeded to strip me and before I put a condom on she said it was a safe time of the month and I didn't need it. We had sex on the floor in the dining room and then I carried her to the couch with me still inside her. I rolled her over and fingered her clit from behind until she came and then I came in her.
Renee came around the corner with a video camera and said, "Good job, I got most of it on tape." Karen put a robe on and told me to stop as I tried to cover up. Renee is Karen's half sister.
Karen told me that unless I do what she and Renee wanted they would give the tape to my girlfriend. I didn't want to lose my girlfriend so I said, "What do I have to do?"
Karen said, "Renee and I want you to give yourself as a gift to us for certain occasions. Like for my birthday I want you to owe me a night from 7pm to 7am the next day. The holidays you will give yourself to us are Christmas, Mother's Day, our birthdays, marriage anniversaries and divorce anniversaries."
Karen said, "I get you 5 days a year and Renee will get you six since she has been married twice." They told me if I can't make it the day they want me then I owe them 2 makeup days and I need to be at their house from 7pm to 7am the next day. Also, I had to be naked the whole time and entertain whomever they had over.
Karen said tonight is her night and we may as well start now. Karen had me suck her pussy as she watched TV and Renee watched us. After she had an orgasm Renee stripped and spread her legs. I licked and sucked Renee and she told me to finger her and I did until she also had an orgasm.
I got hard again and Karen stoked me and said, "don't cum until I say it is OK."
Renee slipped me in her pussy and I fucked her for twenty minutes. Renee is 6' tall and has small breasts but she was thrusting hard against me as I pumped into her. She had an orgasm and held me inside her for a few minutes.
Renee said, "Thanks Ken but I need to go. I am looking forward to having you at my house," and she got dressed and left.
