With a surprise!

You'd known that some girls had extremely sensitive nipples, and a small single-digit percentage could even have orgasms purely through stimulating them. But you knew that was super rare. So you were understandably surprised when the moment your dainty brown fingers gave Eleanor's pink nubs the gentlest of pinches, she jolted like an electric shock went shooting through her entire body.

"Oh! Careful there, cowboy! Those are..." She gave a surprisingly bashful smile at you. "...those are kinda sensitive."

Kinda, huh? You didn't move your hands, not playing with Eleanor's nipples yet you also didn't remove your hands. Eleanor resumed her tittyfuck, rubbing her warm, soft tits around your throbbing cock.

"Aw, baby... I love the way your willy is throbbin' against my girls! Feels like a heartbeat on my boobies!" she cooed.

With only your precum and what you realized was a thin sheen of Eleanor's own sweat to act as lubricant, there was a lot of friction. But given how much give the deep flesh of Eleanor's breasts had, the friction actually felt pretty good. You'd seen tittifucks in porn and they usually needed lube to fully fascilitate, but it looked like Eleanor's sheer size meant she could make do without, if to a limited degree. But the moment Eleanor got going again, you gave her nipples a good tweak.

"Oh! Careful, baby! You might-" TUG! "KYAAAAAAHHHHNNN!"

Your face stared in awe and wonder at the unexpected arcs of alabaster liquid that came from Eleanor's nipples. That smell... You collected some from her titflesh on your finger, tasting it with a tentative lick.

"Milk?"

Eleanor's face was bright red. Her tits were stationary in your lap and around your cock, her hands moving to cover her face in a surprising break in the seducer's confidence. "Oooh... Ya'll found my secret..." she whined. "Yeah, ol' Ellie, raised on a South Carolina dairy farm... G'head and make yer jokes, cowboy..."

Her blue, bespectaccled eyes were tearing up... For a girl who'd been eagerly and confidently rubbing and titfucking your cock and took charge after she found a scrawny naked guy in the empty hallways during the big game...

She looked surprisingly ****.

...And that was coming from the petite naked guy in the girls' bathroom!
