Any guesses on how much cum she has swallowed?

She is 27 years old and we have been married for 5 years. She says she had close to 20 boyfriends before we were married and she sucked all of their cocks, all the time. She lets me cum in her mouth only after she has been fucked by someone else (friends, relatives, girlfriend's husbands, etc.). Is there any way to guess at how much cum she has swallowed in her life? Cups? Pints? Quarts? Gallons?!!!

That whore has swallowed at least 2 gallons per mate, so that would be about 40 gallons?

Let's see, about 1/2 fluid ounce per load. Assuming she gave each boyfriend an average of 100 blowjobs, that would be 1000 fluid ounces or 7.8 gallons of cum.

You need to introduce her to the pornshop gloryhole. She could get LOTS of cum there.

I love to be humilated over my little 3 inch dick.
I watch you bareback her then I clean up.

Well, thanks for the great estimates. For the first four years of our marriage, she used to swallow a load from me probably twice a week. So according to the same calcualating method: that would be 4 X 52 X 2 which equals 416 loads or 208 ounces. That's an additional 1.6 gallons. If you add the guys she has sucked off in the last year that would be another 1/2 gallon or so. A conservative estimate would probably be aound 10 gallons total. Does that sound about right? DAMN!!!! To think my wife has swallowed 10 gallons of cum is unbelievable! No wonder she is getting chunky - I don't know how many calories are in a shot of sperm, but it must be pretty high in protein.

No calories in jizz, just high grade protein. I know I'd be adding at least a few loads a week to that total if I was anywhere near her. I'd love to use her as my fuck toy.
