I fuck my best friend in a bdsm session

I have fun with her I play with her breasts, I twist her nipples and then I fuck her with a harness. I get tired and decide to take a nap from her and leave her tied up. but unfortunately I did not tie the rope well she unties and lets go, she decides to take revenge she ties me while I take a rest, wakes me up and takes off my clothes, whips me, pulls my ears, plays with my incredible breasts and then fucks me with a strapon.
