"Are you alright, Mom? Do you need my help?" I asked out of genuine concern, ready to lift her off at any moment she asked. "Don't be stubborn and ask for my help if you really need it, since I really don't want to be rolling you around on a wheel chair tomorrow because you can't walk."
"I-I'm fine, Kafi...T-There's nothing you need to worry about at all...." My mother said as she took deep breaths to relax herself and her muscles down there that were gripping my penis, while looking down at her vagina's hole that had actually expanded in size after taking my dick in and was the size of a golfball, which scared her.
"...I-I'm just a bit scared that my lips down there will be loose after taking your penis in, since I've never seen them enlarge in such a way."
"Nothing like that should happen, mom, since, just like you said, the human body is quite versatile and can go through all sorts of abuse without any permanent damage."
