Under one roof, the two carnal desires intersect and begin to devour each other. The father-in-law's sense of guilt towards her husband increases his pleasure, causing the young wife's body to turn red, and seeing her like that stimulates his twisted carnal desires. The daughter-in-law has become an obedient sex slave, and he instinctively devours her for sex! She climaxes and convulses!
