In the dimly lit clinic, twin brothers, both curious and aroused, give in to their gay desires. One dresses up as a doctor, his white coat barely containing his excitement. He examines his brother, running his hands over his smooth skin, making him shiver with anticipation. The 'doctor' produces a large, realistic dildo, lubing it up before slowly pushing it into his brother's tight hole, making him gasp and moan. The 'patient' begs for more, his own cock rock hard, eager to feel his brother's real cock inside him next.
