My wife, Sally, is light skin 5ft 5 inch, 34DD and blonde. She has never been with anyone else except for me, which hasn't bothered me until one night.
Sally: That was some great sex! You know I finished twice, right?
Me: Really?
Sally: Yeah! I have always been curious how endowed your are. I mean, it must be pretty big for making me cum twice, right?
Me: hmm, I'm not too sure. Maybe 7 inches?
Sally: Well, let's check!
Sally goes through our junk drawer to find measuring tape and returns to the bedroom with it.
Sally: Awww, you're not hard anymore. Let's fix that.
Sally starts to suck me off, and I can feel my cock growing once more.
Sally: There! Now let's see....
She places the measuring tape at the base of my cock, and traces along my now fully erect cock with the measuring tape.
Sally: Alright.... So far 5 inches.... 6 inches... You're 6.5 inches! Wow! I think thats pretty big, right? Though I have nothing to compare it to. Im just not too sure, since this is the only cock I have fucked. I am pretty sure 5 Inches is average though.
Me: oh! Really? Damn, I thought I'd at least be 7 inches! yeah, I think 5 inches is average, so I suppose Im above average.
Sally: Well, 6.5 inches is big enough for me! It obviously does the job! I mean, I haaaaave .....always wondered what another cock would feel like though.
That comment left me wondering. So the next day I looked online and bought a couple of dildos. A 7 inch and 8 inch dildo.
Me: Hey babe! We should try something new tonight.
Sally: oooooo! Ok.
As we're going through the motion of foreplay, I asked Sally to put on a blindfold. After several minutes I made her cum orally.
Me: Alright, ready for the surprise?
Sally: Yes! Yes! Yes!
I grabbed the 7 inch dildo and slowly inserted it into her.
Sally: ooooo! A new toy I see. How lovely!
She already owned vibrators and dildos, but they were coincidentally smaller than my cock. Anyways, I started going deeper, and deeper, and eventually I got to the end!
Sally: OH! That's fairly far! I've... I don't think I've been touch there before! More!
Me: That's it, babe. Well unless....
Sally: Unless what? Give me more!
Me: ok, you asked for it.
I swapped out for the 8 inch dildo, and started going deeper with that one.
Sally: OH MY! YES! YES!! Don't stop! Deeper!
