Your wife will be the judge

Your friend Josh always boasts how big of a cock he has, and today, and today your wife has decided to settle it all once and for all. She's always so horny, and it's not uncommon for your friends to see her in very revealing outfits, or even slap her ass from time to time. And you're ok with.

She asked you both to get naked, and she did as well.

"Wow" was her first word. "The difference is... quite a lot."

She grabs your cock with her right hand. She only needs to close her hand to fully cover you. But with Josh, that's a whole different story. He was at least three times bigger than you, and his glans was huge. She started jerking both of you off, and she chuckled when she saw how different her movement was with each hand: She uses a couple of fingers to masturbate you, but long, firm movements of her whole left hand to masturbate your friends.

"Amazing" she said.

"I told you" Josh smirks.

"I wonder if you also cum different... Honey! Why don't we do this? If he cums more than you, he can fuck me right now, what do you say?"

You loved the idea, so you accepted immediately. She placed her bra on the bed and continued stroking both of you simultaneously. At times, she leaned forward to suck on Josh hard, although she did not suck you. After watching your wife masturbate your big-dicked friend, pleasure was too much and you came. She aimed your dick towards her bra, and have you cum into the cup. You shot three thin little ropes of semen.

"Alright. That's what you usually cum, sweetie. Now, let's see Josh..."

Now she could use both her hands to masturbate him, and she enjoyed it so much. She used her mouth a lot more as well. After several minutes, Josh also came, and your wife aimed his cock towards the other cup of her bra. However, he shot rope after rope of tick, very sticky semen, leaving a big puddle of pearly white on your wife's garment. She was completely amazed.

"Wow!! Now, THAT is a load!" She said with a pleasant smile. "Sorry, sweetie, your friend has to fuck me now!" She added, shrugging, as if it were something casual, like eating the last slice of pizza.

And you loved it as Josh started kissing your wife, and she started stroking him to get him hard once again.
