She easily slides the dildo back inside of her and sighs deeply. Her pace as significantly quickened, possibly due to the obvious discomfort and frustration that you're experiencing. She loves that you're suffering.
After about a minute of deeply pounding the toy, she looks up at you.
"I'm gonna cum soon. Do you want to finally see what that looks like?", she says, implying that you've never made her cum. "You've done a good job not squirting yet. So, I've decided that your little boy peeny is going to cum at the same time as me. My REAL man has put me in a veeeerrry generous mood."
She smiles slyly. "However, you have some choices as to HOW you're going to cum... well, they're not YOUR choices, per se. I'll decide for you. Regardless, all of MY choices end with you licking up your own cum"
Pick up the pace stroking while she tells you HER choices.
