You abstained for days...and your horniness factor is to the max...you thought you'd blow right away...but she has amazing vag control and takes you to the peak then backs off...because she's loving it too and you both want it to go on forever. But all good things must cum to an end, she finally clamps it hard and you release a splooge tsunami into her, so much it feels like your dick has to back out to give it room...
