Some lube and some loving

"That's a hell of a boast," Roy replied, as he began to remove his pants. He tossed them to the side, along with his boxers, leaving him in nothing but a T-shirt (and his socks, which apparently were still on). But before he had a chance to take that off too, he was surprised by Gwen taking his cock in her hands. It was hard, almost painfully so, and stood up proudly in her grasp.

"Holy fuck, Roy, you could split a girl in half with this thing," she said in awe. Roy was a little taken back by her reaction. He'd measured himself before, of course, but he didn't think he was that impressive.

"It's, like, only six and a half inches," he said, with a mixture of pride and embarrassment.

"Yeah, six and a half long," she continued as she started to absentmindedly pump her hand up and down it's length, her tail wagging picking up quite a bit of speed. "How wide around is it? This thing's like a fucking can of coke!"

Roy laughed. "I never thought to measure the circumference of my dick."

Gwen didn't seem to notice his words, though. She moved off the bed and onto the floor, pulling Roy along so his legs were hanging off the side. Before she got back to it though, she seemed to have an idea. "Wait there a sec, and stay hard," she said, as she moved across the room and started rooting around in her dresser.

"Why would I go anywhere?" he asked. "My cock's out and I'm in the bed of the sexiest girl I've ever known."

"Fuckin' A, that's right," she said, echoing the sentiment. She returned to the bedside and got down on her knees, her low bed putting her chest right at the height of Roy's cock. Roy could now see the object of her frantic search, and to his joy, it was a tube of lube.

"Whatcha planning to do with that?" Roy asked, bemused, as she began to squirt out a handful of the substance and liberally lube up his shaft. He could see her tail hadn't stopped, still moving at the frantic pace that was set when she first saw him bottomless.

"Well, this stuff is safe to ingest, so I'm probably gonna sandwich you between my tits, pump you until you're ready to paint the fucking walls, and then let you blast off down my throat," she replied nonchalantly.

"...fucking A," Roy replied under his breath.

When she finally thought he was sufficiently lubed, she got herself in on the action, completely lubing up her whole chest. Then she scooched herself forward between his legs, and placed him right between both of her tits. Even just feeling her soft skin along his length, combined with the lovely slipperyness of the lube, almost got him close. Luckily, Roy had some experience (in at least one of the timelines) with controlling himself, and waited for the show to begin in earnest.

And begin it did. As promised, she wrapped her massive chest right around him, nearly encircling his dick completely. To Roy, it was like heaven. He could die now and he'd be the happiest man on earth.

"Aw fuck," she said, a little disappointed. "Maybe a little too thick. Usually I can surround the dang thing."

"What, have you done this before?" Roy asked, trying desperately not to blow so early in the game.

"I'm in my third year of college," she replied snarkily, a smirk on her face. "This isn't the first dick I've had between my tits." Under her breath, she added, "Might be my new favorite, though."

Roy smiled down at her, sighing sarcastically. "I guess I'll have to settle for that."

She began to pump herself up and down his rod, slowly and surely, holding her bountiful breasts enclosed with both of her arms. Roy groaned as she started, his thickness trapped in her beautiful marshmallow prison.

"Fuck, Gwen, how big are those tits?" he asked incredulously.

"Psh, like you haven't stolen one of my bras to check," she said, still pumping along his length.

"I... am... a... gentleman... thank you very much," he said haltingly between groans of pleasure.

"Well then, Sir Fuckboy," she said, trying not to laugh, "I'll have you know these are 100% all natural, home grown, certified G-cup bazongas."

"Fuuuuck," was all he could reply.

"You know what the really fucked part is?" she continued, picking up speed. "I think they might still be growing."

He spent a minute or so in silence, just enjoying the wonderful feeling of his first titfuck. He tried not to think of anything other than her, and the sensations he was feeling. He wanted to savor this.

Eventually, Roy sucked in a sharp breath of air between his teeth. "Fuck Gwen, I'm gonna cum."

Gwen frowned up at him, although her eyes still held a smile. "Aww, already? I hadn't even put it in my mouth yet..."

"Well, do it quick then!" he shouted with urgency.

She let his girth free suddenly, mockingly saying, "Yes Sir, Fuckboy!" as she did so, and leaned her head forward. She had only just put his head between her lips when his eruption began, and true to her word, it was the hardest Roy had ever cum in his life. He felt like every drop he had went down her throat, his balls draining in massive spurts, and sure enough, she took it all without complaint. After the first blast, his head was halfway into her mouth. He let her stop it there, which was probably for the best, because with this girth it was probably all she could fit. Also, the way she kept licking the underside of it to coax him on didn't hurt.She gulped down every massive load greedily, her eyes never closing, always looking right up into his, her tail moving back and forth like a metronome.

When it was all over, Roy flopped back onto the bed, panting. "Holy shit, Gwen. Where the fuck did you learn that?"

She licked her lips, moistening them with her tongue, and smiled. "No gag reflex. Never had one. Found out when I was thirteen and tried to deepthroat my toothbrush."

He propped himself back up onto his elbows to look at her. "Why'd you do that?"

She shrugged, looking back at him as she gave his quickly softening member a cute little kiss. "Curiosity. Now, the important question is, do you think you've got more than one shot in you?"

Roy laughed at her little display of affection. "Yeah, just give me some time to recover. Although if it's anything like that, I'm going to be dehydrated pretty soon."
