When BigmommaKat gets tired, she has to lay down. She knows this and makes it worth her effort. She orders her slave to the sofa to lay down. When he is comfy on the sofa, she is happy to lay down over him. She knows that he will be uncomfortable but she has to lay down. When she feels better, she gets up and lets him recover from her weight.
After a good work out, Lady Cathy has to lay down. She calls her slave to her workout bench. She has him lay down. As soon as he lays down, she strips down to her lingerie and lays on top of him. She smothers his face in her massive tits and enjoys his struggles for air. She knows that she is heavy so she pulls him up and shoves his face in tits for fun.
