Age hurts the volume...and distance lol...along with the time duration between ejacs. At 19 I could shoot down low flying aircraft lol. Once laying on my back in bed whilst gf gave bj...she was not a cim type lady...so gave her the 3 second launch warning so she can bail...had first 2 blasts hit the headboard, the third hit myself in the eye. It burned like hell lol.
Another gf could buy herself some sleep time by getting rid of a frisky kherg and his morning wood via quick bj...back then took only 10 strokes lol...she was a cimsw kinda gal...but commented how it tasted different from day to day...
And of course sneaking in a bj in your mum's basement during family gatherings cimsw was essential but once a volume issue meant "oh gee sorry mum can you get a paper towel i think my gf spilled a bit of your alfredo on her blouse...NO she'll get it mum...please sit mum...I'll take it to her..." LOL...
