Keep your end of the agreement

You feel the money in your pocket and unsure as you are you realise you are going to service the two large cocks either side of you.

You grasp both shafts and gently stroke the full length of both dicks. You are mesmorised as you pull the foreskins back and forward over their glistening glands. The ebony cock is very responsive and hardens quickly. You release the other one so you can pay it more attention. You gently masterbate the big dick as your other hand carefully neads and squeezes his heavy balls. Pre cum oozes from the dark cock end. You hear moaning from the other side of the partition as the large black cock throbs from your careful attention. You are amazed as you watch his big balls tighten up and his big cock visibly expand in your hand before a thick rope of cum shoots from the end of his prick. You continue to milk the long shaft as two more streams of cum shoot from his black dick. The strong smell of semen and cock fills the cubicle.

You are quietly happy that you have managed to draw such a huge load from this anonymous cock. You look at the heavy black cock on display and tentatively bring your lips to his balls and kiss them. Hesitantly you plant a soft kiss on the end of his dick. You silently so good bye to the first cock your lips have ever come in contact with as he withdraws his appendage.

Your eyes turn to the second cock protruding from the other side. It is rock hard and the red head is seeping pre cum. This could be the easiest money you've ever made. Do you get him off quickly or do you expand on your new experience?
