Girls can you lapsit 135 pounds guy?

i am a guy... me weight is 135 pounds today i sat on my cousin's lap.. she is around 130 pounds.. she could easily bear my weight for more than 20 mins... I began to wonder how could a girl whose weight is being less than mine could bear my weight for such a long time.. Is it possible for any girl whose weight is 130 pounds to hold a guy who weighs 135 pounds on her lap?
