Not long.

As Janine starts to increase her pace on your cock, you start to realise why she likes this position, it gives her control. Holding on for dear life, you grab her hips and decide to try to get her off before she gets you off.

Reaching down with your right hand, you start to jerk Janine's cock in an attempt to get her off before you spurt deep into the condom. Hearing Janine moan in ecstasy as you increase your pace on her cock nearly sends you over the edge. Barely holding on, you rapidly jerk her cock until you see her squirming, desperately trying not to cum before you do, before she finally gives in to the pleasure and cums all over your hand. Meanwhile, at approximately the same time as Janine came on your hand, her ass tightened around your cock as you came deep into the condom.
