A painful awakening and a makeshift cumdump

That evening Enzo fell asleep in Susan's bedroom, with her lips around his cock. He was so unbearably horny that all he could think about was the fat MILF's warm, wet mouth... He didn't care about the fact that he was being held prisoner in his girlfriend's house, and he barely heard the thumping in the next room as Allie got pounded by her new baby-daddy. He slept well, his jizz flowing down Susan's throat in a steady trickle... Punctuated by the occasional thick wad, as he reached orgasm after orgasm.

But just like the day before, he was in for a rude awakening.

The first thing he noticed is that his balls ached. There was no longer anyone suckling his shaft, which stuck up angrily from his naked body. The tip was leaking thin, clear pre-cum, but not nearly fast enough to relieve the pressure building in his swollen testicles.

Fuck... Marcus DID **** me, he thought, opening his eyes. And not just the strechy-stuff... Huh?

He sat up the moment he noticed Allie, who was sitting at the foot of the bed and stroking his ankle.

"Wakey wakey," his girlfriend said softly. She was wearing a skimpy purple negligee, one hand on her belly while the other continued patting her boyfriend. "Ooh... That looks like it hurts. Marcus took my Mom a couple hours ago, but I guess your balls still aren't empty, huh?"

"Uh... I guess," Enzo mumbled, rubbing his eyes. Then he reached for the blanket to cover himself, but Allie stopped him.

"I read the label on the meds he gave you," she said matter-of-factly. "You need to keep relieving the pressure, or else you could really get hurt. Marcus said I could come help you... He'll be fine with just Mom for the next few minutes."

"I... Um..." Enzo sat up straighter, wincing from the pain between his legs. "Y-yeah, I'd like that. Thank you so much..."

As he reached out to caress his girlfriend, she reached down to the floor and picked up a long, green object. It was Allie's favorite reusable coffee cup: a long, thin metal cylinder, with a hinged opening in the top about the size of a ping-pong ball. It was smaller than most, but Allie liked the way it fit in her backpack's water bottle holster.

"Here, this should work. Your penis will fit, right?" She handed Enzo the container, placing it in the hand he was about to grope her with. "Careful, it's full. Don't spill any... I don't think it'll work without the, um, filling."

Even before he glanced inside, Enzo knew exactly what he was holding. His first clue was in the weight of the container: heavy, but the contents were thick enough that it didn't slosh around much. Then he was hit with the smell, which he recognized instantly... After all, the Local boy had spent most of the previous day swallowing Marcus's ****-enhanced semen.

"Ah--I, uh, Allie, why--" He stopped short as his girlfriend began guiding his hand down towards his crotch.

"You might want to kneel on the bed, so you can sorta put it in downward, like this--Sit up, yeah--Like I said, you don't wanna spill any... Oh, wait!" As she guided her stunned boyfriend into a kneeling position, Allie started giggling. "It won't matter if you spill. You'll be refilling it as you go--Well, as you cum."

Enzo chuckled nervously, still not quite believing the predicament he was in. Allie's hand was on his cock now, as she lined up its swollen-yet-still-unimpressive girth with the coffee cup's opening. He could see the Alpha's semen now: the container was nearly overflowing with thick white goop...

...And it was very thick, even thicker than the many ****-enhanced loads that Enzo had swallowed in the last 24 hours. Rather than sloshing back and forth, it almost looked like it was... Jiggling?

"Oh, we put some jello mix in there," Allie said, when she noticed his curious gaze. "Plenty of my spit, too... I helped Marcus fill it. C'mon, give it a try!"

"Can't we..." Enzo cleared his throat, the tip of his cock twitching just inches from the white jelly. "Do we really need to do this?"

Allie raised an eyebrow. "What do you mean? Your balls look like they're about to explode."

"Well, uh... When you came in, and you said you were gonna 'help me,' I thought you meant... I mean, um, I thought that we were gonna..." He gave Allie an awkward grin, looking her nearly-naked body up and down.

"What? Oh. Oh!" His girlfriend giggled, shaking her head. "Sorry, but no... We can't. Marcus wants me back in a few minutes, and he says you'll need to keep draining those balls for at least five or six more hours. And that's if you don't take any more meds."

"I..." Enzo was about to ask whether that included drinking Marcus's enhanced seed, but he stopped himself: he had no intention of doing that either way. "I don't w-want to, um... Put my dick in... This. Can't I just masturbate?"

"Look at your cock, babe. You're pretty raw... I think you need to fuck something nice and soft." Allie leaned in closer, practically whispering as she continued: "c'mon, Enzo... Babe... fuck Marcus's cum. Do it for me, and for those poor, aching balls..."

As she talked, she pushed the container towards Enzo's trembling cock. Before he could stop it, the tip was sinking inside.

The partially-jellied cum was warm, slimy, and felt absolutely perfect around Enzo's sore shaft. Even as he cringed with disgust, he let out a satisfied sigh. "F-fuck... I'm gonna--"

"Let it out," Allie purred, stroking his shoulder. "Let it all out."

There was an audible splurt as Enzo added more jizz to the mixture. As his erupting cock sank deeper inside the goo-filled container, it started leaking onto his lap. But by that point, Enzo didn't care: he was in heaven, far too busy to worry about the slime trickling down his bare legs.

"Ungh... Oh God, fuck..." He took the cup from Allie, grabbing it with both hands and starting to hump it harder and harder. More jizz was spilling onto him with every thrust, but within moments his balls clenched again and the lost goop was replaced.

"You're fucking my boyfriend's cum," Allie continued, her lips nearly touching Enzo's ear. "Fuck it for as long as you can... Mix your Local cum with his strong, thick Alpha seed... And when it gets too thin, too watery... Come find me. I'll help you get more, okay?"

With that she pulled away, leaving Enzo kneeling on the bed. As he kept humping the metal container, she pranced off to her own bedroom... Where her real boyfriend was waiting.
