You're so sweet to say that.
I really like the way you're trying to please me by being so considerate. After all, it must be so hard being all alone in a private, secluded room with your sexy friend, and having her getting ready to show you her sexy lingerie. Are you sure you can control yourself?
You won't get too excited thinking about those silky panties as they slide up my legs, caress my thighs and go up to barely cover up my hot, wet pussy? Will you?
