(Ok, here's where a mindfuck becomes a bit more literal, probably the only time I can do this with it being gods without any hearing about it in the comments) It's ear stuff

Athena was on Olympus, trying to solve the mystery, men were acting strange, and Artemis had all but vanished. Athena was in her study, looking at the chalkboards, of possible solutions to the mystery.

Chaos? No, gods would have known
Act of Zeus? No, others would have stopped him
Titans? No, defeated
Giants? No defeated
Possible Olympian? Aphrodite, explains sexual part Hypnos? Explains mind manipulation?
Prophecy? possible, unknown
Outside manipulation? Likely.

She suddenly felt someone approach. Turning, she saw Zeus, Poseidon and Hades, walking in.

"Oh, what are you three doing here?" She asked.

"Well, Hestia and Demeter are out cold, and our wives are broken, so, we're going after you, then we fuck Aphrodite stupid." Zeus said.

"What? What is the meaning of this?" Athena asked, confused.

"We're going to use you make you cum till your brain is mush." Poseidon said.

Athena grabbed Aegis and her spear. Zeus held his master bolt and threw it, hitting Athena, zapping her and making her fall to the ground, her clothes burning up on her slightly. Poseidon held his Trident, and summoned a wave of water, forcing her into a wall, tearing her clothes up as this happened. Athena gasped for air, as she was released. She was naked, when she saw her father and uncles surround her, and removed their robes.

Athena looked around, and she took note, Zeus was the largest cock, having a large girth and impressive length. Poseidon was technically thicker than Zeus, but he had a shorter cock than his younger brother. Hades had the longest cock, but not as thick as Zeus. Athena's eyes drifted down, seeing that Zeus had testicles the size of apples, Poseidon had testicles comparable to kiwis, while Hades had Grape fruit sized testicles.

Athena's mind was...filling with thoughts of lewd actions. She pulled her mind back, what happened? She was a maiden goddess, she shouldn't have such thoughts.

"Now, we can either do this willingly, or forcefully." Zeus said.

Athena looked around, uncertain of what to do.

She felt her golden hair gripped and pulled forward, and had her face pulled into Zeus's balls, smelling the musty and powerful stench. Her mind was wishing for this in some way. She felt Zeus's cock harden against her face, before she looked up, seeing the pillar that Zeus used to breed thousands of women. He pulled her head away and threw her onto a bench, his brothers grabbing her arms and legs, pinning her down, as Zeus moved so that his cock, was on a direct path, into her mouth, and down her throat.

Zeus grabbed her shoulders and slammed his cock into her throat, making Athena gag as the large cock entered her virgin throat. She struggled as she couldn't breathe, the cock pumping in her throat and hitting her stomach, making her feel like she needs to barf, but couldn't as the cock blocked her throat. She suddenly felt both of her breasts were suddenly kissed and licked. Hades and Poseidon began to suck on her nipples, making them stand up and harden from the suction. The two gods released her breasts, before smirking and moving lower down her body.

Athena tried to close her legs, before she suddenly felt a liquid spew into her throat, pushing into her stomach, and Zeus pulling his cock out. She tasted Zeus cum as he pulled out of her mouth and sprayed her face with cum. She sat up, only to see Poseidon and Hades on the table, and grabbed her hair.

"Well Athena, I can see why my son likes your daughter." Poseidon said.

Athena tried to turn her head, but the kept her facing forward, as their cocks rubbed on her ears.

"What are you doing?" She asked, panicked and confused.

"Simple, we're going to fuck your brain up." Hades said.

"That's not how it works! Your cocks are too big to fit inside of the ear canal!" Athena yelled, fearful.

"Well, good thing you're a goddess." Zeus said, sitting down in a chair.

Poseidon and Hades began to press their cocks on Athena's ears. The two gods focused and smiled, changing Athena's physical form to changer her head so that her ears would open up, and allow access directly to her brain. The two smirked, before pulling back and slamming into Athena's ears, their cocks pushing into the Goddess's skull, and brain. Her eyes widened as her brain was getting fucked. Athena was mumbling, but her body was shaking, before the two gods pulled back and thrust in again. Her eyes crossed as her brain was getting turned into mush

Poseidon and Hades smiled, thrusting faster, gripping Athena's hair, letting them thrust faster. The two began to develop a pattern, as one pushed into her brain, the other pulled out. Athena's brain, though holding infinite knowledge, was still limited by it's size. Athena felt her mind getting fucked, every thought, every idea was getting pushed around by cock. Her mouth hung open, her tongue lolling out, panting heavily.

"p..pp..ppleash...shhhtop." She strangled out.

She tried to resist, but felt more and more of her ability to use her mind vanish. Suddenly Both gods slammed in, cramming her skull with their cocks and brain, before adding the third part, cum. As They released cum from their cocks, the hot gooey substance mixed in with her brain. As her brain filled with cum, some leaked out through there tear ducts and nose. The two gods pulled out and released Athena.

She was breathing...that was about it.

"Looks like we fucked her brain dead." Hades said.

"Does that make her part of your domain now?" Zeus asked.

"Hell if I know." Hades said, the three brothers walking away.

"So who should we try next?" Poseidon said.

"How about we fuck Sally Jackson?" Zeus said.

"Works with me." Hades said.

Athena fell face first, her ass up in the air.
