All the way.

Emboldened by the kiss, Zack brought his hands up to the back of Chloe's bra, and fumbled for the clasp. He had an insatiable need to taste Chloe's tits. His inexperience with bras caused Chloe to giggle even with her mouth over his.

Detaching his lips from hers, Zack defensibly said, “Stock mocking me.”

“I'm not mocking you,” Chloe smiled, her forehead against Zack's,” I just find it funny,” She removed her arms from around his neck and brought them to the clasp, and quickly removed the bra. Her tits, now removed from their constraints, spilled out and bounced right In front of him.

He looked at them for a moment, nice pink nipples, slightly larger than normal aureola, with the nipples standing out to attention due to her state, there were goosebumps all over her breasts. Zack wasn't sure whether they came from Chloe's nervousness, horniness, or from the slightly chilly air in the cave, but Zack didn't care as he proceeded to take her right nipple in his mouth.

Chloe moaned and wrapped her arms around his head as Zack began to work on her hard nipples. He realized her nipples were sensitive, but he wondered just how much. Even as he began to suck her nipple, he brought his hand up to her left breast and teased the other one, letting it roll on his hand. He enjoyed the feel of them, since he wasn't able to get a real good feel before. Zack's other hand moved down the small of her back and grabbed her ass. Her ass wasn't as big as Victoria’s, but there was still some there, and it was Chloe's, so he didn't care.

After some time had passed, Zack switched nipples in order to give the other one some attention with his mouth. He licked this one, rolling it around and flicking it. The taste of saltiness from her seat mixed in with the rain made him hotter.

“Ahhh, Zack!” Chloe cried out lustfully, increasing the speed of her hips grinding against Zack's cock. Just like the night before. Zack was about to cum, so he grabbed Chloe's waist, and pushed her down slightly further and brought his own hips up to make the dry humping feel better.

Unlike the night before, their climax's came at the exact same time. Chloe stopped her grinding and wrapped her hands tight around Zack's head, her lustful cry filling the cave. Zack let out a grunt into Chloe's breasts as his cum stained another pair of boxers.

“You're still hard?” Chloe said after coming down off the post-sex high. She rubbed her mound against his cock and Zack winced since he was still sensitive, but the heat inside of him hadn't completely gone away.

Zack moved his head out of Chloe's breasts and touched his forehead to hers, “I want to be inside of you.”

Chloe smiled and stood up. Her panty clad pussy was right in front of him and he could see the wetness on her them. The sight gave them the almost irresistible urge to dive in, but he kept him self back and pulled off his own boxers letting his member free. It pointed up towards Chloe like a diving rod.

Chloe stared at it for a second and Zack wasn't sure what she was thinking. Was she scared of it? She then looked back into Zack's eyes, and he could tell their was some hesitation about this. Zack realized it was a combination of her anxieties about her body and anxieties over their quickly changing relationship, but one quick twitch of his cock caught her eyes, and all of that disappeared in an instant. Chloe hooked her fingers into her panties and slipped them off. She removed them from one leg and then the other and Zack finally got an eyeful of pussy.

The first thing that caught his eye was the trimmed patch of hair on right above her pussy. It was as red as the hair on the top of her head which gave Zack a big rush to know. He looked at her slit, the urge to lick it, to taste his best friend/love's pussy became to much, and Zack listed his head and began to lap up her juices.

“Zack!” Chloe cried again as she grabbed his hair with both of her hands to keep herself stead as he licked at her pussy. Her pussy juices tasted sweet, and had a hint of saltiness from her sweat just like her tits. He moves further up and found her clit and licked at it. Her cries were almost constant by now, only punctuated by her breathing. Zack brought his tongue back down, and inserted his tongue into her pussy.

Finding all of that favorable, Zack ran his tongue up and down her slit, spearing her pussy, attacking her clit, until she began to cum again. She spasmed above him placing her one of her hands on the rock he was leaning on and let out a lustful cry. Zack lapped up the juices coming out of her pussy.

Chloe breathed heavily still leaning on the rock as Zack moved his head out of the way. He gently coaxed her down until she was sitting on his lap again. Her pussy pushing his cock into his stomach. They kissed again, deep, but slow. Zack knew he wasn't going to be able to hold back now.
