As I started texting a note to your sister's boyfriend my cock started to stir in my pants thinking back to the scene of you on the kitchen table taking the hard cock of your daughter's boyfriend deep into your sweet pussy. His cock was glistening with your pussy juices as we watched the shaft of his cock stroking in and out, your butterfly pussy lips grasping the shaft of his thick cock as he withdrew from you. The orgasmic expression on your face said it all as he drove his long thick cock into you and held his hips slammed against yours as he unleashed volley after volley of cum deep inside you. Later you told me that you could feel his cock pulsating and stretching your pussy and the feeling of being stuffed full of his cock made you orgasm several times while fucking.
I sent my text to your sister's boyfriend to see what they were up to and asked if they wanted to come over for a BBQ. A few moments went by before I received his reply saying they were out shopping however, they could be over by around 4 or so. I let him know that 4 would be great as it gave us time to put things together for grilling and have some chill time by the pool. I let you know of the plans and you just smiled and headed off for the kitchen to get things ready for later in the day. I sat there in my recliner thinking of what mischievous thoughts were running through your mind while thinking to myself, I wonder if I'll get the opportunity to have a taste of your sister.
A little about the family dynamics, both sisters were divorced and both had been married to black men. I on the other hand was white and your sister's boyfriend was black. Your sister had once asked you, after she found out that we were dating, could I satisfy your needs sexually. You responded yes, no worries there! She hadn't really believed you until one Saturday morning she had stopped by and saw my car in the driveway. She knocked on the door and there was no response. As she came around to the side of the house she heard the screams of your orgasms coming out through the balcony window. She texted you and said "sounds like you were having fun this morning, text me when you are free". When you met up with her later that afternoon she asked you what was going on that you had so much fun. You told your sister that I had brought you to several orgasms by using my tongue, fingers and vibrators before turning you face down and ass up and proceeded to fuck you in the asshole.
You let me know that her jaw was on the floor when you shared the details of our love making session. Anyway, your kids were grown and out of the house and all of them accepted me into the family as I treated you respectfully and took care of their mom. While growing up, the neighbor kids especially the boys, always enjoyed coming over to the house as you were always making something good in the kitchen and on weekends you never wore a bra and your 42DD breasts had not dropped a bit standing proudly on your chest with big eraser sized nipples. Your boys always got teased from their friends how lucky they were to have a fox for a mom and how much they would love to get a hold of your big sexy tits. Your sister's kids were younger and still in middle school. Your sister had not received the wonderful big tits that you did however, had an ass that was like two cantaloupes in a bag and giggled and just asked to be handled and fucked doggy style.
It seemed like time was flying by and your sister was ringing the doorbell and had then walked right in. This was the norm for your sister and you as the two of you shared everything. Her boyfriend soon followed behind with a couple of bags of goodies to include all the fixings for margaritas. I knew what your sister had in mind as she knew that Tequila always got you hammered relatively quickly. At a prior party you had gotten so bad off that I had to carry you up the stairs and put you in bed or you would have passed out in the living room with all the guests watching. It was during that party that you were dancing with your sister's boyfriend and things were getting heated as you were twerking your butt on the front of his shorts to the beat of the music and it wasn't long before he responded to you and was at full mast. You could easily feel his hard cock through his shorts rubbing against your sexy ass. As the song changed to a slow grind you turned to face him as his hands moved up along the sides of your torso and he caressed your large voluptuous breasts. You whispered to him asking if he wanted to put his hard cock between your tits. He responded by reaching back and grabbing your ass with his big muscular hands and pulling you into him. You could feel his hard cock throbbing against your stomach with desire giving you your answer. Your sister then stepped in and switched us back to our respective partners for the remainder of the evening before I had to take you upstairs.
