Unexpected Development While Going Out to Play with a Friend

After returning to the B&B with my friend, he jokingly said that if I didn't accompany him to the bar for drinks, he'd tie me up and play
Before I could figure out the situation, I was tied up in the room and had a ball gag stuffed in my mouth

Feeling the shameful drip of saliva and the pleasure of my swollen, aching nipples…
My body unable to move, but my lower body was honestly hard
