I don't understand Russian but it seems she was telling him to try something new. That's what my ex-gf told me too before she pulled out her strap-on dildo. I agreed to it and that got me hooked on getting assfucked by females. Now I carry around a strap-on dildo in the hope that I will meet up with females who will sodomize me. And it was also the genesis for me becoming bisexual.
I LOVE what Olga's wearing - I lust for lingerie. I LOVE her eating/licking his ass - and would love to have her do that to mine. But, WOW, without any lube, she really rammed that dong in the first time. I'd was a bit more ease than that.
