I cum first

You finally spew your load, a few scant seconds before Bob, laughing as you do so. “It’s ok, Bob” you laugh “I’ll wear a condom so you don’t get cum on your hand”.
Knowing your victory may be short-lived, you try to enjoy the hand job all the more the next day. As Bob’s warm hand strokes your rubber-encased member, you watch Tawny Roberts strip from her cowgirl uniform and finger herself. The more you watch, the more you feel the pressure under the condom building. The feeling of another hand on your cock makes the handjob all the better, making you have to do no work, and still get the wonderful erotic benefits. Finally, bob massages your cock into submission and you hear the squishy sound of the condom fill up and Bob quickly pulls his hand away, forcing you to finish the last few seconds yourself.
The next day, as you show up, Bob already has a spot on the couch ready and porn running. “I get to choose the challenge now, right?” he asks.
“Ya” you confirm, “loser picks”.
"ok" he pauses for a moment thinking how to get you back "same thing, no condom".

You sit down next to your old friend again and begin the same race you had two days before. Considering the fact that bob had not jerked off when he gave you a hand job, you know that you are screwed. you quickly discover that this is true, as he explodes shortly after you sit down and begin to jerk.

Knowing you are going to have Bob’s juices on your hand, you spend the next day thinking about how to get him back. When you show up in his room, his cock is already straight up and hard as hell. As you wrapped your fingers around it, you realize it wasn’t as bad as you thought it would be. It is actually somewhat comfortable, with your fingers encircling his rock hard cock, which was at the same time soft and smooth. As you stroke, you felt the warmth of his penis as the silky skin moves with your hand. Unlike he did, you use my other hand to jerk yourself off along with him, because of how horny you feel.

“Oh, that’s good” he says “slower, slower” you laugh, knowing what it feels like to have someone else jerk you off, then slow your pace, giving his penis a light squeeze as you work your way up and down it. You began to feel his cock swell even more, filling up with cum, and you begin massaging the underside with your fingers, pushing the cum up, making him want to explode. Finally, he does, his warm seaman running all over your fingers and the back of your hand. you quickly wipe it off, but with no running water nearby, you can't wash your hands and have to sleep for the night with the salty smell of Bob’s cum on you.

However, the next night, as you again come into Bob's room, it is your choice for the game....
