Get the Bag sweat mug.
When you and your gf go hiking in the woods alone. When you get tired and take a rest you become horny and you and your partner get nude at this time you take your sack and stretch over her eyes and fart in her mouth. While this is happening the sweat off of your ass and balls drips all over her face creating the Alaskan sweat bag.
Bro me and my gf went hiking and I gave her the best Alaskan sweat bag I've ever seen.

Hiking through the Alaskan wilderness and when you begin to get tired and get extremely horny and your partner and yourself get naked and you stretch you sack over his or hers face and fart in their mouth. At the same time since you have been hiking your sweat is dripping on his or hers face
