Aphrodite and Ares Greek Mythology

Aphrodite and Ares Greek Mythology 

So, she started an affair with someone as destructive and as violent as herself: Ares. 

Helios, however, saw them and informed Hephaestus, after which the cuckolded god made sure to devise a fine bronze net, which ensnared the couple the next time they lay together in bed. To add insult to injury, Hephaestus called upon all the other gods to laugh at the adulterers and freed them only after Poseidon agreed to pay for their release.
