In a combined effort, Kat and Scott made their way upstairs. It was a bit slow at first, especially with Kat running all six of her hands over her half of their form, but movement became natural after a while. Kat playfully bit Scott's ear while she plunged three fingers into their vagina, causing them to almost trip up the stairs. Scott steeled himself in response, getting to the top and swinging open the door to his room.
Wasting no time, Scott whirled Kat's half around, allowing Kat to climb her half on the bed. Her legs rested in a V-shape, with her feet dangling off the other side. Scott's half leaned against the edge, holding them up with his legs.
As soon as they reached the bed, Kat lengthened her neck a bit more to face her lover, coming in for a sexually charged kiss. While their tongues danced, Kat brought a second hand to play with her pussy, letting the other four roam across her tower tits and six nipples. Scott brought one of his hands down to the base of his pulsating member, now drooling with pre-cum. He relented for a bit, not wanting to release his load too quickly.
It didn't take much for him to be submerged under the waves of pleasure that were pouring out from their conjoined form. Scott subconsciously made a throaty moan, constantly surprising himself by making noises he would expect from his girlfriend. He gently bit Kat's bottom lip, feeling the sensation coming from Kat's end as well. Their horns occasionally rubbed up against each other, a constant reminder of their presence. This masturbation, or whatever they were doing, felt better than anything that Scott had ever experienced.
Before long, Kat's half was approaching orgasm. Scott clenched the sheets, waiting for the inevitable climax, almost biting Kat's tongue while he did. However, it never came, and he felt Kat's hands stop what they were doing and fall to her side. Kat pulled herself away, enjoying the look on Scott's face.
"Why did you, ah, stop?" Scott barely managed, sweeping a hand through his wild mane.
Kat grinned. "I thought of something that I want to try. I think we'll both like it," Kat promised, lowering her neck down towards Scott's erection. Carefully, Kat began to wrap her neck around it, starting at the base. She brought it around once, and then again. The coils were wrapped tightly around his girth, but were loose enough to still be comfortable. Kat brought her neck straight out, getting a close look at the almost seven inches of cock that were still exposed. She felt her warm breath on the tip of his dick, and the strange sensation of having living flesh wrapped a new set of genitalia. Finally, Kat opened her mouth and began to take the rest of the protruding member into it, groaning as she felt her own lips wrapped around her boyfriend's dick.
"Oh fuck," Scott moaned, feeling himself inside of Kat's mouth. He had never thought he would know what it was like to give a blowjob, but he realized that Kat was going to teach him firsthand. Kat moved her many limbs back to their previous positions, gently massaging her own half as she continued to blow her conjoined lover. Scott reached out and grabbed one of Kat's horns, steadying himself against the bed with the other. He felt a bit helpless as Kat did all of the work for them.
After he steadied himself, he felt the coils around his cock begin to move and vibrate a little. He gasped, looking down at his girlfriend, who was staring up at him from the head of his dick. The corners of her mouth were turned up in what would have been a mischievous smile as the coils continued to move around his member.
It didn't take long before the two were brought over the edge. Scott cried out with Kat's voice as they both came at the same time. Kat's hands fell limply across her spasming form, her snatch cumming violently as a result of the feedback coming from Scott's half. On the other side, Kat kept her mouth over the tip of Scott's member, feeling Scott's dick shoot load after massive load down her incredibly long throat, glad that her gag reflex seemed to be non-existent.
After what seemed like an eternity their orgasms had stopped. Kat loosened her coils around Scott's dick, slowly sliding her mouth off of the end. Giving the tip a final kiss, she slid off and back up to eye-level. Before Scott could stop her, Kat went back for another kiss, immediately giving Scott a mouthful of his own seed. Scott swallowed it, followed by a series of coughs. Kat smiled and swallowed the rest of his load, which was busy traveling down the length of her throat like a snake.
"Have I ever told you how good you taste?" Kat asked, licking her lips.
Scott sputtered a bit more. "Must not be for me," he replied, not feeling all that angry at her trick.
"It's an acquired taste," Kat said, wrapping herself closely around Scott's shoulders and kissing him on his cheek.
"Didn't think I would find out what giving a blowjob felt like," Scott remarked weakly, feeling quite a bit drained from their bout.
"Didn't think I would find out how good receiving one felt like," Kat retorted, causing them both to giggle. "Maybe I should give them more often," Kat offered.
Scott nodded, moving to get them off of the bed. After standing both of them up, they caught their reflection in the mirror on the other side of his room.
"Don't we look sexy?" Kat said, noticing the mirror as well. Kat winked at their reflection. "I think if we shaved your half, we would look perfect," Kat added with a touch of sarcasm.
Scott stared at the mirror, seeing him and his girlfriend completely for the first time since the game had started. A copy of Kat's face, complete with a pair of horns and a blanket of hair stared back, looking strange from on top of his still hairy, male body. Wrapped around his torso was the neck of his girlfriend, now his twin, making a kissy face at him. He could barely see the oddity of Kat's torso sticking out of his ass behind him, six arms in various positions below the base of her neck. They both felt his penis, which was still at half mast, start to inflate once again.
"My, my. We're quite insatiable, aren't we," Kat remarked. After she said that, they heard a loud cry from downstairs.
"Speaking of that..." Scott said, evoking laughter from both of them. "Why don't we give them a bit longer? They seem like they're still going at it," he pointed out.
"You're just full of good ideas today, boyfriend," Kat said with a grin as she led them back to the bed.
