Miraculously, you've kept your shirt and boxers

Although everything looked brown from the mud, you were relieved to notice the remaining tatters of your shirt and your surprisingly resilient underwear was still on your body. Still in your lying position, you laid your head back to catch your breath and for the dizziness to subside.

The respite was brief because you suddenly felt Tiffany pulling your underwear off of you. Sarah screamed and covered her eyes. You grabbed on to your underwear and shouted, "Tiffany, what the hell are you doing!" "Sam, trust me. You do not want to keep these muddy clothes on." She said sternly, unlike her usually bubbly self. "Sarah, take off his shirt while I get this off." Sarah, still covering her eyes, shook her head. You clung on to your boxers harder. "Tiffany, please!" Tiffany sighed, relaxed her grip for a moment then said, "This is so you don't chafe your dick Sam. If you want to risk infection, then fine, keep them on." "Fine..." you muttered. "Don't be such a baby," Tiffany responded and gripped your underwear again, ready to yank them off.
