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?"
