Yes.

"...ok, I'll try," she says. Diana nods at her encouragingly.

Sophie looks up at you and your cock. You pull up a chair to rest for a moment as she starts unbuttoning her shirt again, this time a little faster than before. As the inner swell of her small breasts are again revealed, you feel yourself getting even harder. It's all you can do not to touch yourself- but as soon as you have that thought, Diana looks over at you and smiles at your obvious arousal. She reaches out and gently begins caressing your dick. She's not pumping you off or anything, just giving you excruciatingly delightful rushes of pleasure, up and down your shaft.

And Sophie notices. She flushes slightly as she watches Diana stroke you, and in moments she's fully unbuttoned. She hesitated for only a moment before shrugging out of her shirt, revealing the most perfectly round, tiny, perky breasts you've ever seen. Her dark nipples are small, and yes, they look like they are beginning to stand at attention.

Diana grips you a little more firmly and you begin to push into her slightly. You look over at her and find to your surprise that she's watching Sophie closely. You know she'd never break professionalism and admit it, but you wonder if she finds Sophie attractive.

"Should I keep going?" Sophie asks.

"It depends," Diana responds, "Do you feel turned on enough to want to try oral sex again, or do you need more time to get aroused?"
