Ask her if that was enough to satisfy her

"And was that enough to satisfy you?" you ask, looking her in her eyes with a sly smirk on your face. "Or did it just leave you wanting more?"

"Well David, it was good. But it's never the same as the real thing." Her hand reaches down and brushes against your rapidly hardening cock. "Why, are you offering to help satisfy my needs?"

"It seems like it's the polite thing to do, doesn't it? I mean it's partially my fault that you're like this, plus you and Tia are so close. I don't think she'd want you to be left frustrated either." you respond, moving your hands onto her hips, the sexual energy building between you.

"You're right David. We are very close, and she's always been so good about sharing her things with me. I bet if you don't help me she'd be very upset with you. We don't want that to happen, do we?" she asks, pressing her body against yours, grinding her pelvis into your thigh.

"No we don't, Nicky. So why are we wasting our time talking?"
