After making all those changes to public sex, I could hardly resist... well, testing them out. Seeing the businessman's erection tenting his boxer briefs, the way his dick twitched and pulsed at the slightest stimulation with so much lust in the air, I had to feel it for myself.
First, though, I opened the book, and made one last change:
"While refusing to be groped is considered rude, reacting sexually to it is considered just as taboo. Men will try their hardest to keep their composure when being fondled, resisting cumming for as long as they can. And of course, the hornier they get, the more cum they produce..."
Satisfied, I closed the book, returned it to my bag, and set off across the bus. I wouldn't keep this new clause active *forever*, but... well, something seemed incredibly hot about watching this hung, horny stud of a man try to continue his phone call as normal while I pleasured every inch of his huge dick.
When I stood just a few inches away from him he gave me a brief uncomfortable look, but, as I dropped to my knees and reached forward towards his straining bulge, the expression faded into one of polite appreciation. I almost laughed to myself — my changes to public groping apparently didn't extend to general ideas of personal space. Still, no harm done. And now, I could have my fun...
I started with his balls. The fabric of his boxer briefs, stretched to its limit, showed each one clearly, and had so much give that they bobbed freely with the movements of the train. I reached forward and grasped one in each hand, fingers barely making it around their front halves, and gentle squeezed. Above me, the man gasped, knees suddenly shaking as pleasure shot through him. A moment later and he was back to his phone call, voice businesslike despite his straining arousal, and the fact that he was leaning into my touch.
Grinning, I moved on to my prize: the dick itself. With one hand still cupping the man's melon sized balls, I reached the other up to the clearly outlined head of his dick, stroking down its length and letting out an involuntary moan at just how big he felt. Setting aside my last leftover twinge of awkwardness at doing this in public, I lean forward and nuzzle my face into his bulge, breathing in the potent, arousing smell of him. My own erection almost aches below my underwear, my dick leaking pre almost as fast as his.
Above me, the man's voice is stuttering, deep and breathy with arousal as his hand trembles around his phone.
I could stop there, or spend the rest of the train ride nuzzling into him, feeling the length and girth of him through his boxer briefs. Or, I could make him cum... I wonder what would happen if I pulled his waistband down...?
