She said I was her fucktoy

So there I was, bent over the bed, face down, buck naked & the feeling of some type of oil being poured down my ass crack. By shivering at how suddenly my asspussy felt so wet, it also looked like I was wiggling my ass in a sexy manner judging by my friend Alma & her reply of "Oh yeah baby. That's how you move that ass! Now jus relax & open up for mommy a lil bit."
I kinda whimpered like a bitch I guess when her tip rubbed the entrance of my asspussy & she leaned over & whispered again "Jus relax baby & enjoy it". My asscheeks flexed inward to protect my virginity but upon finding out there was no pain, I relaxed my asspussy muscles and by doing that, I mistakenly sunk downward & BOOM! I was penetrated. I sucked in my breath & held in in shock paused absolutely still as the shock of her size entered were nothing that size had ever been before. I moaned at this intrusion but I was so stoked that finally I could feel what a woman feels when having her pussy fucked. After a few minutes of flexing and relaxing I thought for sure I was now ready to be fucked like a proper bitch in heat.
But suddenly she pulled away & grabbing an ass cheek in each hand, she spread me wide open & tongue fucked me. " OMG" I cried out. "What are you doing to me" as my body tingles & went a bit haywire at this wonderful wonderful feeling my asspussy was experiencing. "OMG, deeper mommy, deeper" fuck my asspussy. Take it, its all yours mommy" was about all I could say as my body started to confuse in weird ways. I mean, it felt like my asspussy was trying to fuck her tongue as opposed to the opposite of her tongue fucking me.
I moaned to her that I was ready & she laughed and said that I wasn't even close to being ready. I told her that I had already handled her so easily a few minutes ago & so what was the problem. That's when she laughed even louder & her next words sent chills of pleasure fear & desire up and down my body.
She said " You haven't handled anything yet. Baby, that was my pinkie finger earlier, not mommy's she-cock. Jus her pinky".
What was I to do?
