Srimad Bhagavatam Canto 10, Chapter 47, Text 62

SB 10.47.62

ya vai sriyarcitam ajadibhir apta-kamair
 yogesvarair api yad atmani rasa-gosthyam
krsnasya tad bhagavatah caranaravindam
 nyastam stanesu vijahuh parirabhya tapam
 
Translation: 
 
The goddess of fortune herself, along with Lord Brahma and all the other demigods, who are masters of yogic perfection, can worship the lotus feet of Krsna only within her mind. But during the rasa dance Lord Krsna placed His feet upon these gopis’ breasts, and by embracing those feet the gopis gave up all distress.
