"MOOOO!" Trent bellowed out as he felt the cow push one of his cocks into his ass with the other three cocks surrounding his ass. While it certainly hurt a first, there was something comforting about the being filled with and having his ass surrounded by cocks. The teenager also pressed his chest against his back. It almost felt reassuring. Pappa then crouched down and looked at Trent's cock.
"Well looks like you're already producing precum. Impressive."
Trent then blushed as Pappa put an empty bucket underneath Trent's cock and it slowly filled with precum.
"Let's see how full that bucket is by the time I get back." Pappa said as he walked away
Trent tried to protest, but once again all that came out was moo. Even before Pappa was out of sight, one of the other cows positioned himself in front of Trent, used the first cow to prop itself up and stuck one of his cocks into Trent's mouth. As the second cow was moving in and out, two of the spare cocks were rubbing against Trent's cheeks, with the last one rubbing against his chin. Trent noticed that the second cow was moving back and forth faster than the first one. Out of the corners of his eyes, he saw the other two cows circling them waiting for their turn.
"MMMMMOOOOOOOOOOOOOOOOOOOOOOOOOOO!!" the two cows bellowed together as they emptied their first cocks into Trent. They each removed their first cocks and then inserted their next ones. Trent couldn't help but wonder two things in that moment. How long will it take each cow to empty all their cocks and what is Pappa planning to do with all the precum.
After 45 minutes, the first two cows had each emptied all four of their cocks. As the first two cows exited Trent, the other two didn't give him any time to rest. The one who was now in his ass wasn't only rougher than the last one, it was easily had the thickest cock out of the four. The one in his mouth had much thinner cocks, but had the biggest balls. Unbeknownst to all of them, the bucket Pappa has left under Trent was now overflowing with precum. It wouldn't be another hour after that until Pappa came back. At which point, the cows in Trent pulled out, even though they each had one hard cock left. Pappa grabbed the bucket and was pleasantly surprised at the result, especially after seeing the precum that flowed out of the bucket.
"Looks like I'll have to set up a tube for you later." Pappa said as Trent was almost struggling to stay on all fours "I'll make you a promise boy. If you can give me enough precum to last me for quite a long time in the next month, I'll change you back to a boy. If not, I'll change into a normal cow with all the perks. Freedom to roam, four cocks, only one milking a day and no more emitting aphrodisiacs. I'll even make you the same age as the other cows."
Trent mooed in agreement. "I'll be back with the tube." As soon as Pappa left, the cows descended on Trent again. After ten minutes, Pappa returned with the tube, put it over Trent's cock and made sure it would stay on there with wrapping around his waist. After that, Trent's longest month began. Every waking moment Trent had at least two cocks in him. One thing that Trent noticed is that he didn't cum once.
A full month had passed and Trent knew he gained some weight from all the cum he had inside him, but didn't know how much. He just barely saw Pappa walking towards them. The two cows in him pulled out upon seeing him. Trent looked up at Pappa anxious to find out his fate.
