Draco leaned forward and kissed Harry on the lips before moving back to his neck. Harry moaned under his attention, stretching out his throat to give Draco more access. Draco took it and sucked it so hard that he was practically biting him, scrapping his teeth slightly across his skin. Draco moved down to his collarbone, nudging that hypersensitive part in his clavicle with his tongue. Harry squirmed as the nerves surged from the concentration.
                              
"Whoa... that tickles..." Harry giggled.
                              
Draco smiled as he kissed Harry's chest. "You can't escape me, now, Undesirable Number 1."
                              
"Undesirable?" Harry hedged.
                              
"Desirable Number 1, then?" Draco hummed, glancing up at him with a smirk, before returning to devouring Harry's open chest.
                              
"Holy F'n balls, Draco!" Harry spluttered as Draco took a gentle hold of his nipple with his soft lips.
                              
Draco hadn't gone this far before, as he sucked on his captive prey. Harry lifted off the bed slightly, but Draco didn't stop. Harry was so aroused that it was to the point of pain. Harry pulled uselessly on the cuffs, realizing that they had not set up limits. Harry didn't want him to stop and Draco was acting... taking charge. Harry thought maybe he could get some words out of him in before Draco shut him down. 
                              
"Y-You know...t-that if we are g-going to do things l-like this, we should have a safe w-word," Harry said as Draco continued to give attention to his now tender nipples.
                              
"Safe word?" Draco asked, before continuing to suckle him.
                              
Harry frowned when Draco didn't know the word, but was determined to carry on the conversation. "Safe w-word... it's a word th-that you and I c-can use to ask the other person to stop."
                              
Draco lifted his head up halfway to listen. "Why can't you just say 'stop'?"
                              
"Well, it's a little more complicated than that, Draco," Harry started, but Draco went back to exploring his chest with his tongue. "It's w-when y-you n-need a w-word that... oh fucking Merlin!" 
                              
Draco had gone down Harry's stomach and his abdomen spasmed. Draco found his tickle spot and fixated on it. His lips opening and closing on Harry's skin and Harry couldn't help but squirm.
                              
"We c-can talk about th-this l-later..." Harry stuttered out. He wasn't going to bother wasting time with conversation. 
                              
Draco had advanced further down his body. Harry's heart started thumping faster as he had a feeling where this was going. Draco's pale fingers tugged lightly at his waistband, as he continued his oral assault on his skin. Harry was shaking with anticipation and somewhat in fear. He had only a vague idea what was going to happen, but Draco's grey eyes looked up at him, concerned. He probably could see the panic in his eyes. No one had ever gone this far with him before. Draco smiled wickedly. He was in control. Harry was happy for him, but that didn't mean he wasn't scared. 
                              
"D-Draco?" Harry whispered, hesitantly. He didn't want him to stop, but couldn't quite keep the fear out of his voice.
                              
"Harry? Can I... keep going?" Draco asked, leaning into his hips.
                              
"Yes," Harry said, though slightly uncertain. He didn't know exactly what Draco meant, but he wanted to let him have the power to do whatever he wanted. 
                              
Draco caressed his cheek and maintained eye contact. "Are you okay?"
                              
"Yeah, Draco. I'm fine."
                              
Draco stared at him, as though steeling his resolve, and asked, "Can I take off your boxers?"
                              
Harry almost choked. He went beet red. Holy Dumbledore, he wished he had some experience to fall back on. All he had was Hermione's sex book. "Y-Yeah?" he managed to get out. He hadn't been expecting this. Draco hadn't given much sign that he was ready to go this far. Then again, he had. Harry was still reeling from the feel of Draco's hand around his cock.
