4.5 inches

“4.5 inches that’s pretty big for someone your age” Josh spoke with his sisters cock in his hand.

“Yeah I wonder how big it is now hard.” This was such a confusing situation that Josh hadn’t even realized he measured Liz’s soft cock not hard. Liz began to get aroused with her brothers hand on her member which then began to grow. Josh watched this girl-cock grow in his hand widening his grip.

“Mm your hand feels nice and warm on her Josh”

Once hard Josh sheepishly grabbed the tape again to measure, he was in shock, josh then stuck the start of the tape to his sisters lower abdomen then stretched out passing 4.5, then 5, 6, 7! As Josh measured this monster girl cock he began to get aroused. Finally he stopping at 8.

“Oh my god! Your dick is 8 inches!”

“Is that good?”

“You’re hung as hell!” He replied.

“Well I’m probably not as big as you big brother. Josh stood up. “Haha yeah”

Liz could tell his voice sounded nervous, Josh hadn’t realized he became hard while measuring to which Liz pointed out, “hey, you’re hard too! Let’s compare” Josh new itd be pointless to resist. It was only fair they both saw eachother naked. Josh stripped revealing his dick which pointed out. His sister grabbed the tape, walked over and began to measure Josh, “looks like you’re....7 inches? But, I accidentally saw you naked once. You looked huge?”

“Well, that was when you were almost a foot smaller, and didn’t have something this big to compare to” Josh said embarrassed as he point to Liz’s dick.

“Huh, that makes sense.” Liz replied.
