Colin was listening to Zach's words. Learning from the person that you were first with. Now that posed a strange sort of uncertainty. Did he have to choose who to have sex with first? That could get a bit unfortunate. He didn't know. What if someone was upset with his decision...whenever that happened. He blushed slightly. "What...if you sleep with someone else who doesn't know what they're doing?"
There was a small noise as he felt Zach's hips pushing up against him. He focused on Zach's words, eyes widening slightly. Justin had kissed him there, but did he mean something else? He wasn't sure. "Really? How do you do that?" He wasn't at all sure. And you could use fingers and mouth on someone's bottom? His nose wrinkled slightly. "Doesn't that taste...bad?" This was all very confusing.
A shiver ran up his spine at the feeling of Zach's hands and he slid his hands up along Zach's chest, over his shoulders until they rested on the bed on either side of his head. He wanted to be able to feel Zach's hips against him better. Clearly the best way to do that was to move his own hips back a little. Colin leaned over, pressing his lips to Zach's and making a small noise. Yes, he very much liked this.
