It's Sakura!

His pinkhaired teammate had arrived on the scene. Naruto was surprised. What was she doing here at this time in the middle of the night? His question was soon answered as Sakura began practicing, throwing Shuriken and Kunai at a target on the training grounds. "Phew...", it escaped Naruto. At least she did not know that not even ten feet away from her, he was hiding in the bushes with a half-naked Tenten rubbing against his crotch.

And his attention was promptly drawn to said kunoichi. "Gawd, Naruto-kun, I'm so hot right now... I need you inside me, NOW!", she demanded in a hush as she slipped her panties aside, barely enough for Naruto to get a brief glimpse at her glistening sex before she slowly dropped herself down on his cock.

Both moaned out, trying their hardest to suppress their sounds, as the head of Narutos dick popped into Tentens tight pussy. Naruto did not even know if it was Tentens first time or not, but the girl did not stop to lower her hips onto Narutos until his entire length was buried deep inside her wet sex.

Then suddenly, he felt ripples running through Tentens pussy. Did she just orgasm? Just by him being fully inside of her? Wow, she must've really wanted him badly. Naruto tried to hold back a groan as Tentens tight cunt got even tighter, massaging his dick, giving him a heavenly feeling. Tenten herself bit her lower lip, but she couldn't help but cry out in bliss once, louder than she had intended.

Fearing that she might've been too loud, Naruto peeked through the bushes to see if Sakura had heard Tentens climax.
