Cassie's Pov:
I looked horrified at my mom. I did not want to touch her gross, ugly, monster dick. That sounded sickening.
"I can lick your tits but dick is where I draw the line," I said.
She laughed once more. "Honey, at this point, there are no lines. You deserve all the punishment you get."
She suddenly grabbed my own tits roughly. They were big but definitely not as big as hers. Still, it was more than her hands could hold and she settled and pushed them together, squishing them.
"This should do, don't you think?"
"Wait, what are you thinking? You better not be doing what I think you're about to be doing."
"Oh babygirl, you can't stop me."
She spat on my tits and realized it wasn't gonna be enough.
"Spit on your tits for me, honey buns," she said as she rubbed her disgusting, revolting saliva over my chest.
"No way, I am not helping you in this. You're on your own." If she wanted to fuck my titties, I wasn't going to help her one bit. Or, at least that's what I thought.
She grabbed a hold of my hair again, bunching up a ton of it in her hand, me unable to resist because my wrists her tied chair.
"Spit or I'll really start to pull."
I tried to resist again but she yanked my hair to and fro, leaving me screaming at the top of my lungs as she pulled and pulled. It hurt like a bitch, my eyes closed tight as my head rolled around. She kept yanking it for a whole minute straight before relenting.
"How about now?"
My head throbbed with pain and tears rolled down my face. I certainly wasn't crying because I was scared but getting my hair pulled naturally brought tears to my eyes. I nodded through the tears and started to spit onto my own tits.
"Shit, I forgot, I gotta get this rope off." She reached over to the chest and pulled out some scissors, cutting the rope that crisscrossed along my breasts. Then she smooshed them together as if testing them and pulled on my nipples, causing me to yelp from the pain.
"Now we're cookin' with fire," she said, admiring my breasts and the saliva. She rubbed more of it across my tits until they were coated in spit, shining in the lights of our living room. It was utterly debasing to be reduced to a set of tits that my own mother was about to fuck with her futa dick.
"Bottoms up, I guess." With that rather unceremonious introduction, she slid her dick in between my tits and squeezed them together. I could feel the heat rolling off her massive girldick and it throbbed between my breasts. She was holding them together so tightly that it actually started to hurt.
Then she started to move her hips up and down because her heavy dick poked my chin as it popped into it and disappeared back beneath my tit flesh.
"Shit, that feels good, baby girl. Your boobs are silky smooth."
I was mortified that my tits were being fucked like I was some animal. I wasn't some degenerate boy that fucked anything that moved. I was a girl, precious, cute, and a polite young lady.
"Mom, this is so nasty."
"Shh," she hushed. "I'm trying to fuck your tits."
I groaned in embarrassment at having to be in a situation like this.
She started pumping faster, the crown of her dick constantly bumping into my chin as it pistoned back and forth. Luckily, since my mom had made me coat my tits so liberally in spit, it didn't really hurt. Well, the grip she had on them hurt but the dick itself slid nicely between them.
She pumped it hard, her veiny throbbing cock feeling so disgusting. I just hoped it wouldn't take long to cum and that she wouldn't try to spray it on my face. Please, dear God, don't let her spray spooge on my cute face.
Sometimes, as she pumped in and out, I felt a tingle in my breasts but otherwise it really just felt like I was being used by my mom to jack off. I sighed loudly and hoped it would be over quick.
Kendra's Pov:
My massive girldick was sandwiched between my daughter's titties. I wasn't particularly attracted to her but I knew it would gross her the hell out and I could get a quick orgasm out of it.
God damn did her tits feel nice. They were so pillowy and soft even though they were smaller than my own, which jiggled with each pump. I was holding onto her tits for dear life, feeling them milk my dick like there was no tomorrow.
