Play it cool

You decide not to make a fuss. It feeling this good is probably a sign that it's working. "I was just a little surprised, sorry."

"R-right."

The dryad slowly places her fingers on your back again, and you're prepared this time, not letting out any unfortunate noises, and simply enjoying the incredibly pleasurable feel of her fingers rubbing at the skin on your back. After what feels like a blissful eternity, your entire back is thoroughly covered in her sap.

Her hands move to your shoulders and begin massaging them pleasantly, then rubbing on the back of your neck before removing her hands to collect more the oil-like sap.

You can feel the bruises and aches on your back fading away already, but though most of your body is loosening up as your pains vanish, a certain bit of your anatomy is hardening instead.

Even a normal massage from a woman this attractive would cause most men to struggle with an erection, but the pleasure her hands are imparting on your extra-sensitive skin is leagues above even that.

More sap is rubbed onto your arms and legs, and you feel uncomfortably aware of how great you're feeling when she moves to your backside, hesitating slightly as if embarrassed. She seems determined to finish what she's begun though, and you feel her oiled-up hands kneading your ass cheeks, which has the unintentional effect of making your erection press against the ground, stimulating it further.

You grit your teeth, willing yourself not to cum.
