A very easy challenge

"Loser, I know that you want to taste this whore pussy again." David mock you.
"Thus, I will give you a chance, but you need to do pass the challenge." The big jock smile slyly at you.
You gulped nervously anticipating what cruel plan he have in store for you.

"Worry not, it is a very easy challenge, you just need to **** grip your cock and jerk off, cum in less than 10 sec,and I will let you have chance with MY whore, easy isn't it?" His right hand curled into a fist and he move his hand up and down. You realize it is what David expect of you when he said **** grip

"But it isn't fair to not have a punishment or penalty if you are fail in this easy challenge."

"If you fail, this whore ex-girlfriend of your will have really bad times this week." This time, Carrie is the one who is surprised but David just ignore her.

"It is time to prove that you still love her, maybe with the show of your determination, I will feel bad and give you more chance in the further to be together with the whore, you are my roommates afterall." David voice dripped with sarcasm.
