The victory moves Terry Burton's men level on points with Bradford City at the foot of the table, and means that Steve Coppell's side have now suffered three successive 3-0 defeats.
Wade Small gave the visitors the perfect start when he opening the scoring with a clever chipped goal just nine minutes in to claim his first senior goal for the club.
Wimbledon keeper Steve Banks had to be alert to preserve the lead with a save from an Ivar Ingimarsson header, but the home crowd were stunned when the visitors doubled their advantage midway through the first half.
Adam Nowland centred from the right, and youngster Dean Lewington reacted first to head home from close range.
Reading sent on on-loan striker Lloyd Owusu in a bid to get back into the game but, although Nicky Forster struck the crossbar, struggled to make much impression on a solid Wimbledon backline.
With the hosts committing men upfield, Wimbledon took advantage to put a gloss on the scoreline when the impressive Jobi McAnuff capped a fine personal display with his side's third.
The midfielder drilled a left-footed shot past Marcus Hahnemann at the third attempt to complete the home fans' misery.
