Elizabeth Olsen is a single mother that's still very much in the prime of her life at 38 years old with a 20 year old son had has married and flown the coup at the age of 18 with his high school sweetheart Samantha. Lizzy as she's known to her friends had always been a well endowed and solid woman at 6' even and a 40 28 40nmeasurements and a home gym to help keep her toned.
Lizzy's son Aaron was a giant of a man at 6'5" and built like he was chiseled by Michael Angelo. As Samantha she is significantly smaller than both of them at only 5'8" and a petite built at only 32 20 32, no toning or definition but still takes care of herself. Sam and Aaron have been trying for children since before their marriage but it was only recently they have found out that, although Aaron is in peak health with no issues. It is Sam who has an issue. Sam has damage to her fellopian tube and ovaries as well as no eggs to speak of. This has devastated the couple as they wanted children, several children to call their own.
Upon hearing their plight Lizzy came over and helped they in anyway she could. From cooking to cleaning, laundry to groceries if her efforts could make a difference she did it. One day while she was on a grocery shop Aaron and Sam spoke about asking his mother for help with Sam's infertility by using being not only a surrogate but also an egg donor. Upon her return Lizzy brought in the groceries and with her children put everything away. Once that was done they all sat down to talk and that is when Aaron and Sam asked.
"Mom we want to ask you something very personal and would rather ask you since you are family over any of our friends or a stranger from." Aaron started.
"Sweetheart you know I'd love to help you, what is it?" Lizzy said
"We want you to both be an egg donor and surrogate for us?" Sam said with tears forming in her eyes.
Shocked with the request, Lizzy fell silent for several minutes before asking "So you want to fuck me Aaron?"
"Exactly." he bluntly replied.
"Is this because you are infertile Sam?" Lizzy asked. She just nodded.
"I did say anything so let's do this. As it happens this is my fertile week so let's start tonight." Lizzy said.
That night the family made dinner together but naked. Aaron and Sam had their rhythm but Lizzy was rather awkward this it. Seeing his mother still nervous and apprehensive with their request, Aaron walked up to his mother and kissed her passionately and rubbing his cock along her slit. Feeling her sons cock alone her, Lizzy relaxed at the feeling of a cock down there. After that they had found their rhythm and finished dinner and dishes.
After dinner they all retreated to the master bedroom and made ready for making a baby with Sam and Elizabeth making out to start as Aaron watched and played with them to begin to make them wet. After half an hour Aaron lines up his cock to his mother pussy and slowly plunges in.
"OMG!!! Mom your so tight, wet and hot." Aaron exclaimed moaning.
"OH MMMMYYYYY GGGGAAAAWWWWDDD!!!! Aaron your so big." Elizabeth whimpered.
Once he bottomed out on his mother's cervix Aaron just sat there for a few moments before he slowly slide in and out of her slowly. He kept his pass slow for the next twenty minutes even through several orgasms until he felt the first load of the night boil up from the deepest parts of his balls, through his cock and exploding into his mother. Feeling such a load power into her depths and into her fertile and waiting womb.
After such a powerful load had erupted from him, Aaron laid down behind his mother just slowly pleasured her while Sam kisses her from the front and rubbed bother clit and cock and balls and until they both cummed again and they all fell asleep as they are.
The next morning Lizzy was the first to wake with her sons now fully flaccid cock still in her. So she pleased herself with his cock still. As she was his cock came to life, becoming hard again and his hips slowly thrusting. Almost immediately she had cane again.
"Seems someone is excited about this as we are." Sam whispers to her
"Yeah its been a while since i had such a strong and powerful cock in me." she whispered.
Aaron's hands traveled all over his mother, feeling every little bump and curve.
"Thanks mom you are such a hot fuck. Thank you for doing this it really means a lot to Sam and I." Aaron said with Sam agreeing.
Once again Aaron pimped a hefty load of cum into his mother who now looked like she was three months pregnant with all the come she is now carrying. Sam gave Lizzy a pussy plug to help keep all that valuable cum in as they had breakfast in the noon again. After breakfast Aaron headed to work leaving his naked lovers alone at home.
With their man gone for the day both mother and daughter in law raided the sex toy collection and Sam pulled out her favorite dragon dildo strap on and began slowly giving the anal of a lifetime, in doggy of course, to keep the baby batter in place.
Aaron returns home to find his mother and wife arm in arm in bed with his wife's strap on firmly lodged in the former's arse. So he resolved to have dinner shower and join them for another cum dump.
Over the next two weeks the trio got into a happy and comfortable routine of fucking to make sure Elizabeth had become pregnant. But as her fertile period came and went with a negative result Aaron resolved to continue and provided the strength needed to make it happen so the next month came and went with a negative result and same the third.
But the fourth month success and Elizabeth tested positive with a pregnancy test. Over the first couple of weeks after the result they confirmed with a doctor and went wild with an orgy. All three continues to make love all through the first two months of the pregnancy until month three when Elizabeth begins to grow a bump but more rapidly than expected. So come the next doctors appointment the ultrasound shows not one, not twins, not triplets but quadruplets in her.
With this revelation the family comes together and bonds with one last love making session and the occasional one as the pregnancy progresses.
Aaron and Sam com to worship Elizabeth not only for helping them build a family but also for having a glorious and large belly. With the months rolling by Lizzy's belly grows until the day comes and she delivers 2 healthy baby girls and 2 healthy baby boys.
After returning home the new parents and grandmother all went to their shared bed and rested the night way dreaming about future children and sexual adventures.
