YES!

You stopped for a second. Is it really worth? I mean, it can turn out pretty badly. But all your temptations were driven away by Sue, smiling at you, with lust in her eyes.
"YES!" You almost shouted, with a **** attempt to hug her in your position. "Yes, Big Sis! Please, take care of me, ok?". Sue smiled with a pleasant spark in her eyes, as you blushed after saying this bounding phrase.
"Ok then, Amy, let's start then," she said as she grabbed your cock and started to rub it. You moaned with every squeeze.

"Hmmm, interesting, so easily bound. You are a natural slut, my dear." She whispered to your ear while pushing the dildo deep into your pussy.
"Yes! Yes, I am! For you, Big Sis, I can be the best slut you ever knew!" You cried while plastic-cock reached a new level of deepness. You were so close...
