"I'd like to sit on your lap facing you. Tell us if you need a break. We'll fuck you to death otherwise."
"I will. Have a seat, Grandma," he grinned.
Liz picked up the control for the chair and lowered his legs. The chair was plenty wide for her to straddle him. She reclined the back a little then moved onto the chair with him. Tommy took his cock and rubbed it up and down her slit then put the head at her entrance. He moved his hands to her hips and pulled her hard down onto his cock. His grandmother grunted loudly as he entered. When fully seated she took his face in her hands and kissed him hard then began riding him.
"Damn, Grandma. You're as tight as Marla."
"There hasn't been anything in my pussy but my fingers for the last ten years. I think my dry spell is all over."
"Mom, would you like your granddaughter to fuck your ass while your grandson fucks your pussy?" Cindy asked.
"Bring it on!" Liz replied.
"Marla, there's a purple toy in my bottom dresser drawer. Run up and get it."
Marla ran to the bedroom and returned a moment later with it. Cindy hit the on button to test it then turned it off. She put one end in Marla's pussy. With the device in place, it looked like Marla had a purple cock. Cindy wet the cock end with her mouth then turned it on. She positioned Marla behind her mother then put the end at Liz' pink asshole.
"Go in slowly, Marla. After your in, you're on your own," Cindy instructed her daughter.
Marla pushed slightly. There was no resistance. Her grandmother moaned feeling both the vibrating dildo in her ass and her grandson's swollen cock in her pussy. The vibrations set Tommy off and he filled her pussy with cum. Marla was cumming a moment later and grandma, Liz, soon followed. None of the three slowed down and they continued with orgasm after orgasm for the next ten or so minutes before Liz collapsed on Tommy. Marla and Tommy stopped to give her some rest. Liz' three daughters helped her to the floor. Marla removed the dildo from her pussy and lay down with her face in grandma's pussy to clean up her brother's massive amounts of cum. Marla's mother and aunts each came over to share the cum and each of the women came hard at their first taste from Marla's face and mouth.
After each of the five women had taken their second turn Tommy asked about a short lunch break. Although he was tired the drug gave him need for another ejaculation during lunch. His mother happily accommodated him and shared her gift with the other four.
"Grandma, why does my pre-cum make some of you cum but not mom or Marla?"
"Your aunts and I haven't been exposed to any cum in years. I suspect that effect will wear off pretty soon. It's actually the sperm in you that triggers us and there's very little sperm in pre-cum."
"Do my cousins already know about the condition?"
"Yes. We're all getting together at here tomorrow."
"All eleven women?"
"Yes, and our man. Get plenty of rest tonight, Tommy."
"Are you sure I can do this, grandma?"
"Tommy, you've already cum fifteen times today. Marla told me she's been teaching you how to romance a girl. That's good news. It's a skill you'll need throughout life. Not all women are going to throw themselves at you like we do."
"You really think I'm gonna have time or interest in other women?"
"Yes on both counts. We'll do our best to keep you happy and satisfied but you'll still have desires and needs we can't fill. We're all the same way. If Marla's attracted to someone, I hope she's smart enough to pursue it. Our relationship has to be completely open."
"I see what you mean."
"My dad, your great grandfather, Aaron, was servicing five of us. He saw us all as his women. As we started to have our own lives and lovers it really bothered him. He was a bit possessive. Don't look at us as yours. You provide a wonderful, loving and healing service for each of us but we still need to have lives just like you do."
"Mom, shouldn't we clean up? We have an errand to run," Cindy asked.
Liz looked at the kitchen clock.
"Heaven's yes. Let's go."
Everyone who was finished with lunch headed to the shower. The others finished lunch and joined them. Charlotte and Charlene helped Tommy unload again while in the shower. Tommy was surprised that he wasn't even getting sore. His cock had seen more action today than ever before. After everyone was dressed they loaded into two cars and left. They drove for about twenty minutes before arriving at their destination.
Naomi, Tommy and Marla's great grandmother greeted them at the door. She hugged and kissed everyone but held Tommy's hand the entire time. Naomi was in her middle eighties. Even at that age Tommy could see how attractive she had been at one time. She and Tommy sat on the couch together.
"Tommy, I hear you have something for me."
"That's what the tell me."
"I don't move around very well. How about if Marla or your mom collect it then share with me?"
"Do you have a preference, grandma?"
"I've seen your mother give my husband hundreds of blowjobs but I've never seen Marla give a single one," Naomi replied.
"I think Marla would agree to that."
"Your great grandfather would have asked for a real show?"
"Like what?" Tommy asked.
"While Marla is sucking you, her mother would be eating her and your mom's mother would be eating her. I'd even enjoy that show."
"Aren't you going to get in on the action?"
"Oh heaven's yes. After Marla gives me your cum, she can eat me. Then you start at the back of the line and fuck your way to the front."
"Grandma, were you the creative force behind grandpa?" Cindy asked.
"I came up with most of the craziness that's gone on in this family for the last fifty years. Hopefully one of you has been paying attention. I'm not going to be around much longer to be your director."
"Mom has," Marla laughed.
Naomi clapped her hands, "Everyone naked and in positions. Someone help me with my clothes."
Charlotte and Charlene came to her and helped her undress. Everyone else undressed themselves and got into position. Tommy doubled a towel and put it under him on the couch. Marla took Tommy's cock in her hand and began stroking him. Her mother, Cindy, crawled up behind her and began eating her. Cindy's mother crawled behind her and did the same.
"Now that's pretty. Someone take a picture," Naomi said.
Charlene grabbed her phone and took both pictures and a short video.
"Aunt Char, video this," Marla instructed.
She took some of the pre-cum from the tip of Tommy's cock and held it up to her great grandmother.
"Taste, ggma?" Marla asked grinning.
Naomi opened her mouth and Marla inserted her finger. Naomi flushed and immediately had an orgasm. Everyone watched smiling. When she recovered they were all back at their tasks.
"With just pre-cum? Holy shit, Tommy! What's going to happen when I get your cum in my mouth?"
"You're gonna cum again, grandma," Tommy replied.
It didn't take long for anyone in the group to cum. When Tommy came Marla moved her mouth to Naomi and shared the cum. Naomi immediately came again and squirted. Marla was surprised she had never seen anyone squirt before. She moved her mouth to Naomi's pussy and began licking. Tommy went to Liz and entered her from behind and soon filled her with cum. She rolled over on her back and Charlotte licked her clean. Both orgasmed. Tommy moved next to his mother and entered her. She came quickly and he continued until he came again inside her. She rolled away and Charlene cleaned her with both cumming again. Tommy entered Marla and began to pound her while she licked their great grandmother. Both she and Naomi came. When Tommy came, Marla moved over and laid down allowing her mother to lick her clean. Cindy, as always, came at the touch of her tongue to the semen in her daughter. Tommy knelt between his great grandmother's legs. Everyone stopped what they were doing to watch.
