I love working out. I also love fucking people in the ass. What if I could combine the two???? ------------- It's cardio day, and Sydney walks into the dungeon with her sneakers on. Her sub is naked on the spanking bench with his ass up in the air. Sydney makes him hold her water bottle as she puts on her strapon, grabs some lube and walks over to behind her sub. Little does he know that cardio day involves getting fucked by Sydney and her giant strapon. After a little warm up, Sydney goes balls deep and fucks him so hard his spanking bench travels all the way across the room. Clearly, everyone's heart rate went way up today
