Karen keeps her composure and convinces Doug to volunteer his ass to her

Doug understands by now that he's not getting out of this one. That enormous tool of Karen's is going to be root-deep inside him one way or another, like it or not. All of this has gone too far for Karen to be able to stop herself. If he resists, he'll only make her hurt and angry and he's got no doubt she'll take that out on him in the process of seeking her own relief. Still, he does have a chance here. If he submits...and even makes a show of willing, maybe she'll go easy on him. Granted, that huge girl-dick of hers looks like it could kill Doug, but maybe it won't. Either way, he doesn't have a choice. Doug can see that staring into her eyes and looking at her hungry expression. Well, here goes.

"If you want me," he manages once he's found his voice again, "you can take me. I want you and...I trust you."

That last part seems to register with Karen...make her focus a little more. It's one thing, Doug figures, to just take a guy trying to fight, but quite another to betray a trust once it's given. She nods.

"I'll be gentle, Dougie," she tells him, laying one more huge sloppy kiss on his lips before lifting him from his feet.

She wraps him against her so that his legs are splayed against her huge soft belly as she guides her massive member up to line it up with Doug's butthole. Doug does his best to relax his sphincter, hoping the soap and such from the shower will be enough to lube him. He knows it won't matter much once it starts to go in and soon feels the bulbous head nudging its way into his ass. Doug just lets it happen and is actually amazed when the girlcock begins to work its way into him. If he were in a rational frame of mind, he might have considered that with the development of these massive futa dicks, the male holes for receiving them would naturally develop to allow them to be received. Right now, however, his head is lost in a mixture of new sensations. There is pain at first, but not as much as Doug thought there'd be. More an uncomfortable fullness as he is invaded...and pleasure. There is definitely pleasure and he holds onto that just as he clings to Karen while she continues to ease her way in. This is obviously feeling good for Karen as well from the mewing sounds she's making.

"Oh it's good," she moans, "Fuck your ass is so good around my dick. Oh, I'm almost half way in! You good?"

"Yes," Doug gasps, barely able to find words.

"Ready to take more?" Karen asks eagerly, still pushing.

"Go ahead," he manages, going for broke, "Gimme it all. Make me yours."

Doug doesn't know what inspired him to say that last part. Maybe it's the thought that if Karen gets attached to him, if she sees him as belonging to her, she might protect him from others who might try to take what they wanted from him. It certainly has an effect on her.

"Really?" Karen almost squeaks in sudden excitement, "You wanna be...mine? Like...mine, mine?"

Doug only manages to nod before her pudgy hands grab his hips and she thrusts the rest of her length into him. Again, there's a jolt of pain. While his body can adjust, it wasn't meant to do so quite so quickly. Still, he doesn't resist and just grabs hold of the pleasure and tries to ignore the pain. It's not long before Karen withdraws and slams back into him, starting a rhythmic fuck as she throws her head back.

"Oh fuck yeah!" she practically screams at the ceiling, "I got me my Dougie! I got me my very own boyslut who loves me and wants me to fuck him silly! And I'm gonna do that, oh yeah! I'm gonna fuck you night and day and fill you up with my liquid love! Oh, take my girl cock! Take it!"

The pain is at a minimum now, although still continues slightly due to Karen's enthusiasm. Doug can only hope he'll figure out how to cope. Meantime, however, there's still plenty of pleasure. Karen's massive dong is finding nerve endings in his anal passage he didn't even know he had and is stimulating them mercilessly. Doug's own cock is finding some stimulation too given that, as she fucks him, Karen's huge, soft and silky belly is bouncing and grinding against his railspike-hard erection. After a moment, he sees that her massive tits are bouncing and flopping right in front of his face. Well, Doug is determined to participate, and so he grabs hold of one, giving it a thorough kissing and licking before wrapping his lips around her large nipple and sucking like crazy.

"What are...OOOOO! Fuck that's good!" Karen screetches, her voice raising an octive, "Yeah, Dougie! Suck my titties! Suck 'em good! You're gonna make me cum!"

He's about to cum as well and with one final thrust, Karen clutches Doug to her big body, burying him in fleshy goodness, and blasts her load into him. He cums at about the same time, blasting his onto her belly. All he can do is hold on, shaking with his own ecstasy and feeling her big body trembling around his, not to mention her huge load in his ass. Doug is thankful that she fucked him standing up so that the excess can flow out, falling with wet splats on the shower floor.

After a moment, he chances a look up into her face and sees Karen looking down at him adoringly.

"That was...incredible," he manages once he find his voice.

"Yes it was," Karen grins down at him, "are you mine now?"

"Yep," Doug answers her.

"Then a couple of groundrules you should know about," she tells him as her girlcock slides slowly out of his ass, "One, nobody takes you without my permission. They try, I hurt 'em real bad. Gonna have to share you a little, you know that, but you said you trusted me, so you can trust me to pick girls who will treat you nice. That goes into the second groundrule."

"Which is," Doug says.

"Anybody hurts you, they're dead," she says with a suddenly straight face, "You're mine and I won't tolerate anybody trying to ruin you."

Doug swallows hard. He believes her and is glad that this sudden dark side isn't directed at him. However, Karen's grin returns and she plants several more kisses all over Doug's face as the two of them leave the shower.

"And now," she tells him, "I've got some plans for today I think you'll like."
