13 inches

Ashley began to stroke Duncan’s cock vigorously. His cock began to stiffen a bit and grew larger. Still not getting anywhere fast enough she took one hand and spit on it. She began to stroke his cock again. You couldn’t believe how bold both of them were in front of you and on your bed. Duncan let out a groan of pleasure as his cock hardened further. Ashley stroked faster and faster and told him “come on get hard for me”. After a minute or so Ashley finally got him hard.

His cock stood tall and proud with no assistance from Ashley. His cock was about as thick as a monster can now. You knew he was gonna be big from just how large he was when he was soft. But this was something else you didn’t think cocks could get that big. “Okay let me measure this” Ashley said bewildered from his size. She took the ruler and placed it by his cock and it pushed pass the ruler. “Oh my god just how big are you” she said hysterically. Duncan ate up the attention he was getting. Ashley placed her finger where the ruler ended. She moved the ruler to where her finger was. “13 inches” she announced in a stunned voice.

You were in disbelief too of how big it was hard. Meanwhile Ashley and Duncan looked each other in the eye.
