"Hmm... I doubt they'd fit. On the other hand, if you're so interested in anal..." He murmurs, chuckling evilly as the hand groping her breast slowly crawls down her belly, before reaching her butt. He gives her another squeeze, before gripping the cheek and peeling it apart to reveal her asshole. He immediately forces a thumb in, slowly building up to the same speed of thrusting as the fingers in her pussy.
"Think about it. You could be comfortable... Have a sexy, loving master... A big, thick bristled cock for you to play with all day... Ride when you wish... And, of course, you'd be safe here. We'll take care of you. Come on, now. Just two words. I submit. Just say that... And all this is yours for however long you choose..." He whispers seductively in her ear.
