We were deep into the heat of summer and my tits felt sore constantly, my nipples were rock hard and the ache was unbearable under some bras, all thanks to the friction. I had huge blue veins popping through the swollen pale skin of my breasts already. I needed a top with built in support to go braless comfortably in the disgusting heat, but even that did little to keep them from bouncing and wriggling free from the thin fabric. My huge pink areolas were always in danger of popping out, or even worse, my whole breast could bounce free completely in public. Master knew this so encouraged me to wear these tops often.
One afternoon after running for the train my areola started peaking out of my scoop neck top, this turned him on immediately, and before I knew it his hands were pinching the fabric still covering my breasts when we made our way to our seats. The carriage was fairly empty but anyone walking through would be able to see my swollen nipples being teased through the fabric and my cheeks growing red from such a public milking. After toying and twisting both nipples through the fabric for 5 minutes master pulled the taught fabric down and my teats fell out completely. I felt the cool air lapping at my engorged tits, they pointed to attention and the feeling of them jiggling made my cunt ache. Master quickly attached his wet mouth to my rock hard nipple and sucked it greedily, the ravenous sound of his wet mouth milking me in public made my cunt ache so much more it genuinely hurt between my legs. I could feel my panties getting wet. While his mouth worked my left nipple he kept squeezing and pulling my right nipple in full view of.. anyone.
Suddenly, almost out of nowhere, the ticket inspector appeared. He was absolutely furious and was threatening to report us to the police. Red faced, he made his threats, but his eyes kept drifting back to my swollen pink nipples hanging out. He explained we are lucky we are the only passengers in this part of the train today and he thought we should be arrested. Master immediately called him out for staring at my tits, "I bet you wish you could taste my bitches fat pink nipples, huh?" The inspector was stunned, honestly I was too. He stammered initially, considering his options and then responded sternly, "yes but I want to use her privately". Master smirked deviously, he found this hot. He nodded his head and gave me a shove to get up. I couldn't really believe it, but I was shuffling through the carriage with my sore tits hanging out to go and make some older man cum. I was anxious.
