Zack wants a titfuck.

Zack's mind tried to reason with his cock, but it fighting a battle it couldn't win as lust slowly took over him, especially with the movement of Chloe's soft hand around it as she got a good feel.

“Chloe?”

“Yeah, Zack?” Chloe stopped her movements, and Zack could feel his own lust building up, he wanted to continue, but his brain figured, ow that it had been lost to lust at this point, he would get something better.

“I...um...I just...”

“Spit it out Zack!” Chloe ordered and squeezed his cock. Zack winced, she didn't squeeze hard, but it still slightly hurt. Chloe jumped back at bit after seeing Zack wince, and hurriedly apologized.

“It's fine, it's fine,” Zack reassured Chloe, “It didn't really hurt.”

“Alright, I'll believe that,” Chloe remarked sarcastically, before moving back toward her position, “what is it you want me to do?”

Zack took a deep breath, “I want to fuck your breasts!”

Chloe seemed shocked at his words, “You what...?”

Zack mentally facepalmed, “I'm sorry, just forget I said anything.”

“Zack...” Chloe stood up, his cock brushing her large breasts as she did so, and when she was at her full height, she gave him a peck on the lips, “You've been helping me out with my own issues, so I owe you at least something,” giving him one more peck, she moved over to the bathroom. Zack wondered what she was doing and looked through the door. He saw her panty-clad ass swinging out from under the cabinet as she looked for something. This made him much harder than before.

Zack heard a small thump coming from the cabinet, and watched as Chloe pulled herself out of there holding onto a white bottle and rubbing the top of her head, “You okay?”

“I'm fine. Nothing that's hasn't happened before,” moving back into the bedroom, Chloe opened up the tip of the bottle, and squirted a white substance on her hands. Zack realized she had found some lotion and was using it lubricate her breasts for the tit fuck.

The movements of her breasts and hands mesmerized Zack, but it still didn't stop the question forming at his lips, “How did you know about this?”

Chloe blushed, and averted her eyes, but didn't stop lotioning up her breasts, “I read about it online and figured it would be something good to remember.”

“And the bottle?”

“Found it while I was looking for something else,” Chloe knelled back down and nestled Zack's cock inside her breasts, holding them together. Zack began to move his hips, he had never had a girl give him a tit fuck before. Either they never got that far, or the girl's breasts were too small to even give one. The sensation was different from regular sex or a blowjob, but Zack really enjoyed it, and from what he could hear of Chloe's breathing over his own, she was enjoying it too, as she let out a small moan.

They continued for another minute, but Zack knew he was not going to be able to last much longer, the tightness of the inside of Chloe's breasts and her moans were pushing Zack over the edge. He knew he had to tell Chloe before it was too late.
