"Alright, buddy, here we go..." And with that, Don moved his hands to the waistband of the boxers and pulled them apart. As they stretched and then tore, Chris let out a sound somewhere between a sigh and a groan. He watched the boxers part under Don's large hands and felt a firm but painless tug as they pulled away from his groin and thighs, revealing first his thick patch of pubic hair and then his straining erection. Don tossed the tatters over his shoulder and took in the sight of Chris' naked body. Since he'd always suspected Chris to be straight, he'd tried not to think of him in sexual terms, though he'd always found him good-looking. Given all the recent revelations, he could allow himself to admire his friend in a new light. Chris was hot, there was no other word. He didn't have Don's muscle mass, but his body was luscious nonetheless. Don realized that he wasn't just doing his friend a favor by giving him his first time. He realized that he wanted Chris as much as Chris wanted him. As frightened and weirded out as he'd been by all the size changes, he couldn't deny that some good had come from it all. This was going to be fun!
Don grinned as he moved his mouth closer to Chris' cock. He glanced at its surrounding bush, then back up to Chris' pleading eyes. "Later on, remind me to tell you about trimming". "Huh?" Chris replied, but his question was cut off by the sensation of Don's hot, wet mouth engulfing his penis. Chris leaned his head back onto the floor and moaned. "Oh shit! That feels so fucking good!" He writhed as Don's tongue worked up and down his shaft, lubricating and stimulating it at the same time.
Although Don had gone down on his share of guys, this was a first for him. He'd never dealt with a penis that seemed so small. He effortlessly took its entire length into his mouth, swirling his tongue and salivating. He pushed further down into Chris' groin and moved his lower lip underneath his friend's balls, engulfing them, too. Now his lips and tongue worked all of Chris' package, sending the smaller man into a new round of writhing, his every breath accompanied by gasps and small moans. He opened his eyes and looked down the length of his torso, sweat breaking out along his pale skin. Don's head was bobbing up and down only slightly and his jaw and cheeks worked up and down, in and out as his enlarged mouth and tongue worked their magic. Don glanced up into Chris' eyes, never stopping his ministrations.
The lower half of his face was occupied with other things, but the smile in his eyes was unmistakable. Chris reached down and curled his fingers into Don's hair, stroking the large head with both his hands. His answering smile gradually turned into a look of pained pleasure as he felt his orgasm approaching. He'd already been close before the blowjob began and the sensations Don was giving him made the last part of his journey to climax a short one.
Don realized that Chris was close and pulled off of him. He leaned back on his haunches and watched as Chris' moaning subsided and his breathing returned to normal. One more second, and he would have pushed his friend passed the point of no return.
Chris looked up at Don, blurting, "Christ, don't stop now! That was fucking amazing!"
Don's smile became playfully wicked. "Oh, I'm not nearly done with you yet." He laid himself flat on his stomach, pinning his erection between his abdomen and the floor, then grabbed Chris by both his bare feet and pulled him gently towards him. Chris' eyes widened with surprise and excitement and he uttered an "Oh shit!" as Don lifted his feet into the air, stretching Chris legs above the floor. Don pulled his friend's ass right to his face and planted a large, wet kiss across its entire width. His tongue probed between the firm cheeks and found its mark, eliciting a squeal from Chris. As Don's tongue fluttered from anus to perineum, Chris winced and smiled with pleasure. He had never been touched there sexually and he was realizing how much he'd been missing out. The blowjob had been fantastic, and so was this, but in such a different way. Although he'd backed off from climaxing, his erection had never dwindled and it raged on with this new stimulation.
Don poked his head up from between Chris' legs and met his friends eyes. "So, you like that?" he asked, knowing the question was rhetorical.
"Oh hell, yes" Chris responded breathlessly. "Keep going, Don, please!"
"Glad to, but..." he grimaced a little and shifted his hips over his pinned erection. "The floor is a little uncomfortable. Let's move things to the bed".
"Whatever you say," Chris replied, eager to cooperate and then was surprised again as Don transferred both his feet to one hand and slid his free left hand under Chris' ass and along his lower back. Then Don stood up - or crouched up, being far too big to stand upright in the dorm room - and lifted Chris up, hugging him to his chest as he padded, doubled over and knees bent, to Chris' bed. Chris leaned his face into Don's shoulder and tongued the flesh there, reveling in the taste and smell of this friend, this man, whom he could now call a lover. The next thing he felt was the softness of the matress as Don deposited him on his bed. He saw that Don had placed him with his legs dangling over the edge, one of his feet once again in each of Don's hands.
"Now," his giant friend said, "where were we?"
