Without a doubt, minahs!
I am quite a horny bastard by chinese gals standards, everyday must f**k, sometimes 2-3 times a day. I remember dating this ah lian who worked in a factory who was a self professed sex addict. I banged her until she could not walk and had to take MC from work. She called timeout after 4 months, buay tahan.
I thought I was damn zai, until I met this 22 yr old malay gal who worked at Takashimaya. In 2 months, she literally sucked and f**ked me dry. I had to call the timeout....
