Yes

Walter felt the time was right, so he stretched his tongue out of his mouth, over his cock-covered forehead, past his sons heaving ballsack, and plunging the thick, slimy appendage into Peter's tight, virgin asshole. This alone would have made Peter release all his pent-up spunk, but his dad just had to go the extra mile, and violently mash Samus' tongue against Peter's swollen prostate.

Peter went crosseyed, looking a lot like his dad at that moment, and let out a long, pleasure-filled groan, as his mammoth ballsack tensed up and prepared to fire their squirming payload directly into his dad's stomach. Peter Piper's pink prostate pumped out gallon after gallon of piping hot babybatter, the swimmers inside determined to knock his dad up regardless of there being no ovum.

The jizz thundered down Peter's cockvein, stretching his urethra wide to allow the sheer volume to pass through,flowing down Samus' tight, undulating throat, before finally flooding her belly with cum. The **** of the cumshot was so strong it instantly sprayed from her bellybutton, mouth, nostrils, ears, even squirting out of her tear ducts so she was crying cum.

Her stomach ballooned outwards, looking 9 months pregnant after just the first blast.

Walter was making all kinds of sloppy, throaty, cum-drowned noises, his eyes were almost permanently rolled back into his skull, and his features were quickly becoming obscured by the obscene amount of cum flooding out of his orifices.

His stomach had just settled down and was letting out deep, gurgling rumbles and sloshing noises, the skin stretched taut over the cumflated stomach, when Peter's mighty balls clenched a second time, forcing an even greater deluge down his dad's dilated diaphragm, gushing into the already full organ, causing it to expand even bigger. Walter was now resting on a cumgut the size of a watermelon, and it only got bigger from there.

By the forth cumshot, Walter was beginning to look dangerously full, his belly creaking and groaning, so the jizz decided to find some more space.

The two guys with their limbs still lodged inside Samus' stretched out hole, looked into the dark red tunnel with alarm when they were a sound almost like a toilet flushing. The sound grew louder and louder, until the storm of ballsludge came thundering out of her loose passage, coating the two guys in layers of the thick, white slime. They quickly pulled out before they drowned in the stuff, and watched her ruined hole collapse with nothing to hold it open, the stretched-out walls prolapsing by about 8 inches, and jizz leaking from the inverted rectum in a constant flow.

They could both see the problem instantly, with nothing to plug up her hole, all that valuable cum would go to waste. So, thinking quickly, they took of their belts, and tied both of them around the red butt sock. This caused it to inflate with backed-up ballslime, growing from the size of a red, wrinkly pumpkin between her legs, to a giant trembling beanbag chair-sized prolapse.

Peter shot a few more gallons down his dad's catatonic throat, before getting up to observe the carnage.

His dad was unrecognizable, with a cumflated stomach as big as him, and a tight, red beanbag chair for a prolapse. Cum was dripping out of every hole on his face, his bellybutton, some had even managed to find it's way to her tits, pumping them up from DDs to massive, straining, vein-riddled M-cups, and cum was leaking from her fist-sized nipples.

"Well, dad," Peter said, gazing at the **** form of Samus Aran, "you sure gave that body one hell of a test run."
