Sexual play with patient breathing oxygen

A fully naked patient has a stethoscope with a microphone on her chest and the sound of her heart is recorded, after a minute I put an oxygen mask on her face. The patient is given oxygen at a flow rate of eight liters per minute. In the second minute, I start caressing her pussy, I also sometimes caress her breasts or squeeze her chest. I continue for several minutes and in the ninth minute I start to fuck her. In the last minute of the video I cum on her tummy. In this video, two camera angles are used and the sound of her heart is recorded, unfortunately it is sometimes not heard during movements.
