Grinning broadly, she began unbuttoning her blouse. I
could see part of a sheer white bra and an incredibly
deep cleavage beckoning me. "Now just let me get this
other wrist strapped down and I'll show you some more."

Mesmerized, I allowed her to finish her task and soon
found myself bound by wrist and thigh to the four legs
of the bench.

She then stood in front of me and fulfilled her promise.
Slowly parting the blouse, she wriggled out of it and
stood before me nude from the waist up except for the
sheer bra. NAME_2 skin showed through the gauzy cups, and
brown nipples made dark circles at the tips. "That's
enough for now. Don't want to get you too worked up just
yet. Are you comfortable?" Provide exactly two different responses that are separated with 6 asterisk symbols: ******.
