Orgies

Romans 13:13 Let us walk properly as in the daytime, not in orgies and drunkenness, not in sexual immorality and sensuality, not in quarreling and jealousy.

Galatians 5:19-21 Now the works of the flesh are evident: sexual immorality …  drunkenness, orgies, and things like these. I warn you, as I warned you before, that those who do such things will not inherit the kingdom of God.

1 Peter 4:3-5  The time that is past suffices for doing what the Gentiles want to do, living in sensuality, passions, drunkenness, orgies, drinking parties, and lawless idolatry.  4 With respect to this they are surprised when you do not join them in the same flood of debauchery, and they malign you;  5 but they will give account to him who is ready to judge the living and the dead.

Incest

Leviticus 18:6 None of you shall approach any one of his close relatives to uncover nakedness. I am the LORD.  [Note: ‘Close relatives’ is further defined in Leviticus 18.7-20.  Forbidden sexual relationships are those with one’s father, mother (cf. 1 Cor. 5), sister, granddaughter, father’s or mother’s sister, uncle’s wife, daughter-in-law, sister-in-law, both mother and daughter, the granddaughter of a wife, two sisters while one is still alive, a menstruating woman (perhaps unclean sex outside marriage that is intended to avoid the possibility of pregnancy—cf. Ezekiel 18:6 and 22:10), and a neighbour’s wife.  The list is repeated in part with appropriate judgements in Leviticus 20.10-21.  Another list is given in Deuteronomy 27:20, 22-23.  Cf. Ezekiel 22:9-11.]

2 Samuel 13:11-12 [Amnon wanted to have sex with his sister, Tamar.]  But when she brought them near him to eat, he took hold of her and said to her, "Come, lie with me, my sister."  12 She answered him, "No, my brother, do not violate me, for such a thing is not done in Israel; do not do this outrageous thing.
