Choose blow job

The hand job that you gave Bob made you feel hornier than you would have expected, and you realize this is the perfect time to experiment. "blow job" you announce. "also, when we are doing the challenge, we should switch hands, and the first to cum loses instead of winning"
"ok" bob agrees, "lets do it"
As you grasp Bob's cock, his familiar girth gives you a welcoming sensation. You begin to jerk him off as he jerks you. With another mans penis in your hand and someone elses hand on yours, you are yet again treading on new ground, and you get excited yet again thinking about it. Despite this, you know that you still stand a chance against Bob because you picked up quickly on how to please another man, and you think you can get his cock to blow even before your own excitement peaks. But the question is, do you really want to take the next step?
