Sarah takes a lot of selfies, but she doesn't post them anywhere online. She loves the element of surprise too much to give it away all at once. Instead, she DMs her selfies to anyone and everyone she can. Gossip travels quickly, and pretty soon everyone has heard about Sarah's penchant for naughty private chats, if they haven't already witnessed it first-hand. When one of Sarah's friends alerted her to the #girthgauntlet challenge going on, she had to think long and hard about blowing her cover to join in. All that long and hard thinking got Sarah so stiff, her cock ended up making the decision for her.
