Two is better than one

The sounds of enjoyment turning to ecstasy downstairs have you near desperation as you return to Susan's room. Your cock throbs painfully and precum oozes freely from the tip, smearing her back and staining her skirt. You have little patience for foreplay, and the frenzy is quickly slipping from your control as you tear Gwen's skirt and panties off. Susan stands as quickly as possible, helping you position her on the bed.

"Master, please enjoy her quickly. I will make sure you do not alert the others." The sly grin on Susan's face allows you to push aside any questions and you climb atop your new quarry. After a quick smear of precum on her cunt, you thrust in mightily and cram barely more than the tip in before her tightness forces you to stop. Gwen grunts in pain and fear beneath you, but does not yet awake as you ready for another shove.

Reason is quickly leaving you again, and the next series of thrusts gets you to her cervix long before her body can properly adjust. Her abdomen bulges around your massive cock, and her eyes begin to flutter open just as you thrust in again. Her scream of pain and fear dies as Susan forces a nipple into her mouth, a thick stream of milk causing a gurgle before she has to swallow.

"That's it, sweetie, drink up. You'll need your strength to keep up with him." The depth to which Susan is getting into it only fuels your desire further, and you see Gwen's eyes bug out when she realizes the owner of the tit in her mouth. "It's quite wonderful, honey. You'll just LOVE it when he impregnates you." Gwen struggles more as Susan says this, but is unable to break either of your grips or free her mouth from the bountiful tit-flesh muting her.

Your copious precum lubricates your thrusting quite well, and you begin jack hammering into her. You're thankful the bed is quite sturdy, the noise it makes not nearly as much as what your own did, and the screams of orgasm continue to float up from the living room. With your paws wrapped around Gwen's slim waist and pinning her hands to her sides, you relish the feeling of her pussy stretched to its limit around you. You're at the entrance to her womb, but haven't reached even half way down your cock. How she'll take all of it is something you're quite eager to see.

It takes many minutes and more than a bit of insistence, but eventually Gwen's cervical ring begins to soften and allow you passage. Her muffled screams begin to sound more like moans every so often, and when she fails to capitalize on Susan switching teats on her you know she's succumbing to your musk. As the head of your cock pops in to her unprotected and now extremely fertile uterus, you feel the familiar tingle. Susan recognizes it too, grabbing your head and forcing your muzzle in between her tits just as you howl, the sound muffled between the three not currently in use.

Gwen tenses up when she feels your cock expand, and the first jet of potent sperm sends her over the edge. You release her hands, her body firmly stuck to yours through the enormous head of your cock alone, and she claws at the sheets in a massive orgasm. The second spurt is thicker than the first, and her belly grows visibly from the volume. The imperfect seal allows quite a lot of your cum to flow out in large sticky globs onto the bed, but her stomach still grows larger and larger with every shot.

The quickie allows you to think a little more clearly even as the slower flow of cum continues, but you aren't even close to satisfied. If anything, you're harder than you were when you started, and your every instinct demands that you knot your new mate...somehow. You were up against the back of her womb when your came, and only a little over half of your cock had made it in.

You lean back and look over the sight. Gwen's belly appears at least 5 months along, but shrinks slightly with every aftershock as more of your cum is **** out by the pressure. Her tits, much to your surprise, have already grown at least two cup sizes, presumably from all the milk she's ingested. Susan awaits your decision as Gwen willingly switches to a third nipple, seemingly addicted to the milk they give her.
