Use Violet's big tits

While the offer of the "traditional way" was quite tempting, the entire time she was talking, I couldn't take my eyes off her wonderfully large breasts.

"I... uh," I tried to say.

Violet followed my eyeline and understood. "You never were very subtle about your attraction, you know Christy." Slowly, she lifted her button down over her shoulders until she was just wearing her green bra. "During presentations, or lab meetings, or just day to day work, I caught you staring at me." She reached around her back and unclipped her bra, all while staring right at me. "Well, more specifically these." And then her DD cup breasts were free. They were large and wonderful and I wanted to bury my face right in them. My new dick twitched in anticipation.

Then she sank down to her knees. She was a few inches taller than me, so her breasts were right at the level of my penis.

"Given how much you like them," Violet continued, "it was only fitting that this would be your first experience with them." She leaned forward so that her breasts were almost touching me. "It is for science, of course, but maybe you can enjoy this a bit."

And she grabbed her breasts and squeezed them together. Then with a swiftness I didn't think was possible, she put my hard dick right between her breasts. I couldn't believe it. I was actually titfucking her.

Before she started moving, she said, "Hmm, this needs something." And she bowed her head and stuck out her tongue. Several ropes of saliva pour out of her mouth, covering my dick between her tits. "That should be adequate lubrication. Shall we?"
