"You say that your not like your mother Abi, but just look at all this fat I have to push aside to go deeper." He pulled her in closer to get a better grasp of her ass, which made her well rounded bosom squish into his chest. "It brings me back to the days when your mother and I started going out, when I treated your mother's ass as my greatest enemy since it never let me through easily."
"Hnn~...What about now daddy?" She whimpered as she felt her son getting closer to her most shameful place. "Do you still think the same?"
"Of course not!" He said as a matter of fact and pinched her ass for doubting his ability "That's only how it felt like at the start. After your mother spent a few sleepless nights at my room where I thoroughly played with her butt until dusk broke out, her ass would open up by itself like a flower that had just bloomed whenever it's in my presence."
"Even now, your mother complains that her butt starts twitching when she sits next to me, and drags me to our room so that I can treat her." He spoke like he was her personal doctor, that specialised when her ass started feeling funny.
"I-Is that why you...Hmm~...a-and mommy always say that your going to the bathroom together or need a break, and go away for a few minutes when we watch a movie together?" She too joined in building the story as she was currently very aroused from having her son grope around her butt while she resisted, and wanted to join in on the fun.
She was an arts student when she was in college because she loved anything that involved acting, music or dance since a very young age and acted in several plays before, so she was quite good in improv and making up situation. This was also why she was a bit excited to roleplay with her son since it was the same as being in a two-person play with him which she was elated she could do with her son, even if they were acting out erotic scenarios like the they were in now.
"You were never supposed to find that out, but as embarrassing as it is, it's the truth." He admitted. "But we don't always go away to take care of our business, and sometimes finish the job without going anywhere."
"How would you do that, Daddy?" She asked curiously, as she felt her ass tingle from being teased for this long.
"Well your dad here just slips his hands into her underwear, like what I'm doing right now when no one is looking and only takes it out after your mother is satisfied." He revealed one of the ways he silently satisfied his wife under the table.
"And no one finds out when you're taking care of mom?" She got excited at the thought of her son's hands in her skirt, while a bunch of others she knew were right next to her.
"Well I've perfected the way to use my hands to tame her body without making to much movement, so there's no problem on my end. But your mother on the hand, still can't control her moans after years of being with me and has to use her mouth to cover her wails and act as if she feels warm when her face gets warm, so there has been a few times we've almost been caught because of your mom."
"How did mom react when you two almost got caught? Did she panic and have a breakdown? Or was she cool the whole time?" She asked, wanting to know how it would at that moment where your inches away from being caught and exposed as a pervert who performs such degrading acts in front of others.
"Your mother would show a bunch of different emotions according to the occasion. Like she'd be scared when she was in front of her family, since she was afraid of getting caught by your grandparents...Or how she would be embarrassed when you were around us." He explained her kinky behaviour in front of her daughter. "But no matter what expression she's showing on her face, only one thing would remain the same which was how my hand would be drenched in her fluids after I take them out."
"Does that mean you always carry around tissues, just in case mommy acts up?" She asked, as she knew for sure that she would constantly wet her pants if she was treated in such a way and would always carry a spare underwear in her purse.
"I would use a tissue if there was one nearby. But if there isn't..."
"If there isn't?" She interupted unable to control herself.
"...I'd make her lick her liquids right off my finger and let her take it back into her." He said with a sly smile on his face which made her face flush.
And just as she was wondering how her own honey would taste, her son seemed to have a break through in his mining operation and it looked like he had finally found the core area where the forbidden hole was. She didn't really notice what was going on since she was too absorbed in listening to her son's debaucherous fantasy. But the moment, she could feel a cool breeze hit her delicate asshole she immediately knew that her weakness was exposed.
She tried to clench her ass as a last ditch effort to push away the invaders, but unfortunately for her, her son had already surrounded her exit with his fingers and firmly planted them there, while at the same time using them to keep her cheeks wide open.
"It took me a minute, but it seems like I've finally arrived at my destination." His fingers were just inches away from her most secret place, and she could feel the tips of his fingers near her asshole.
He treated her ass quite rough this whole time and she was pretty sure that he left a few marks while scraping through her ass, which she actually enjoyed. But the moment he came close to her most delicate part, he moved his fingers much more nimbly and delicately, as if he was touching a fragile flower, which made it seem like he was quite experienced in this type of play. This only made her son more mysterious in her eyes, as she simply couldn't see his past self do such intimate actions as if he's done then with several women before.
"T-That means we can finally stop what we're doing right? I mean you should have found out how similar our butts are by now." She asked, as she didn't know why he hadn't taken his hand out of ass even after ploughing all the way to the bottom.
"What are you talking about, Abi?" He asked with his brow raised, as if what she was saying was preposterous. "Sliding my hand through your mother's cheeks was never the hard part. It was always finding the entrance after that and entering which I had to struggle with, because your mother was tight as a pickle jar."
"Only after seeing how easily my finger slips into you, will I know how similar you are to your mother."
