Angels reproducing with humans possible?

[Sean]

6 And the angels which kept not their first estate, but left their own habitation, he hath reserved in everlasting chains under darkness unto the judgment of the great day.(They simply fell)

7 Even as Sodom and Gomorrha, and the cities about them in like manner(cities about them in like manner, NOT ANGELS IN LIKE MANNER), giving themselves over to fornication, and going after strange flesh, are set forth for an example, suffering the vengeance of eternal fire.(Immorality is commonly how humans leave their inheritance or first estate with God, they dont get kicked out of heaven to leave their estate)
