People normally like it when you do stuff with your chest?

You're not dirty, but you're not going to cum first! You're also not sure what you're doing. But normally, when you rub and jostle your chest, the actually dirty people seem to like it. Delilah's definitely looking at it, so you begin slowly....

"Wh-what, you think you can get me off quicker with that? M-mine's so much better than- eep!" She reaches up and starts mirroring your own movements, but stops a little bit in. Are her nipples too sensitive?

"Oh, good, I was hoping you two would use those." Professor Phoebe smiles, her chin resting on her hands as she looks between the two of you. "You know, I was actually thinking of getting mine out for this, but you both might just squirt all over too soon if you saw these babies." She rubs one hand over the top of her chest to emphasise her point, then puts it back to her chin. O-oh man, those words are making you twitch a bit... but Delilah's not looking much better!

Your own little show didn't seem to help much. Maybe you can put your hands to better use?
