Danny spends the next few days barely out his mom's anus. They pump, and fuck and fart and he gets into greasing her butt up and burying his face between her large cheeks. Dad is coming back soon, and they promise to keep their fuck sessions a secret from him.
His mom spent a few hours on the phone one evening and he didn't know who she was talking so long with. Must have been family. Finally she was off the phone, and she came to find her son.
"Who were you talking to for so long, mom?"
"That was your Aunt Margaret."
"How's Aunt Margaret?"
"Fine, honey. She called to tell me that she got a plane ticket to come visit."
"Well, that's nice. When is she coming out?"
"Tomorrow."
"Tomorrow?! For how long?!"
"A week."
"But Dad will be back by then! Tell her it's not a good time and that she can't come!"
"Danny! Don't worry honey, we'll still get to fuck."
She nestled up close to her pouting son, pressing her big tits against him and ran her fingers through his hair. She opened her blouse a little and pulled out a giant tit.
"Suck on Mommy's nipple baby, please."
He lay across her lap and put her mouth on her big fat nipple.
"Don't worry honey. I'll still give you the attention you deserve. Aunt Margaret won't get in the way."
The next afternoon Dianne left to pick up her sister Margaret at the airport while Danny ended up going out. The girls went shopping, came back, and were finishing dinner when Danny walked through the door.
He had not seen his Aunt in several years and they greeted each other warmly, even though Danny had been mad she came at such a time."Hi Aunt Margaret."
"Oh Danny, look how you've grown. Come give me a kiss."
He walked over to his Aunt who was seated next to his mother on the sofa and they kissed each other on the cheek. He looked at her and was stunned how sexy she seemed to him.
Margaret is a few years older than his mom, in her early 50's, with the same fat dick sucking lips, heavy boobs, trim waist and an even wider big bottom. She sat there in the living room in tight khakis and a white tank top that revealed quite a bit of cleavage. Her mature big round boobs hung great in that soft top. Danny stood there for a second almost drooling, taking in her plump thighs hugged tightly by her pants.
"Danny, honey, sit down." Dianne said to her son.
Mom and Aunt Margaret talked with alot of animation on the sofa. Danny noticed the empty glasses of wine as he sat down in the recliner and stared at his Aunt's huge rack and juicy legs. His Aunt's arm was around his mom's shoulder and together they had the most delicious sets of big tits he'd ever seen.
Aunt Margaret got up to go take a pee and Danny conspicuously watched her wide, plump ass make it's way out of the room.
"Aunt Margaret looks great." He commented.
"Yeah, she's got a big fat ass, just like her sister." Dianne said, knowing what was on her son's mind.
"I'm sorry mom, I didn't mean-"
"No, baby, it's Okay. I know you love a nice plump ass. I just hope you'll still want to play with mine later tonight."
