It did not take long for Ethan and Colin to head over to Colin's house, which was good considering that it would mean less time out in public, and less of a risk of being seen by neighbors or drivers. Besides, they didn't want to run into anyone in any way--not yet at least.
They soon reached Colin's house, and walked up the path to the front door. Once inside, they quietly shut the door behind them before taking off their mismatched shoes. As Ethan undid his tie with his one hand, he and Colin walked over to the couch and sat down. It had been a long day for both of them, even without the two of them becoming a two-headed man. They were fortunately that Colin's teenage son was asleep, because he would surely have freaked out if one of his dads was now conjoined to one of his co-workers. But when the two came inside, they did not know that Colin's partner was nearby in the kitchen, and about to come out into the living room.
Oscar was getting some cocoa and was going to relax on the couch with his mug, now that Colin was finally home. But when he went through the kitchen door into the room, he nearly splashed the hot cocoa everywhere when he realized that Colin had another head. He was about to scream, but the conjoined pair quickly got up and covered Oscar's mouth when they realized what would happen: not just the risk of their son waking up, but also of attracting the attention of neighbors. After calming Oscar down and explaining everything--Luke's suit, Ethan's family bonding, the suit's side effects, and running into Colin--the three dads all sat back down and relaxed.
Oscar asked his partner--and his partner--if the effect could extend to him as well. Since Colin had not worn the suit before and was able to fuse with Ethan, it seemed reasonable that he could do the same. He also wanted to still be close to Colin, even if it meant sharing him--in one way or another--with another man. Deciding to see what would happen, Ethan and Colin agreed and scooted over to the side of the couch. Oscar got up from his chair and walked over to the couch, sitting down next to Colin. The two scooted closer, until their arms and legs were next to each other. Soon enough, they began to merge together. The shared arm disappeared, as did the leg, as Oscar's body began to melt into Colin's. It did not take long until the transformation was complete. There was now a three headed man sitting in the room, with two arms, two legs, and three heads on broad shoulders: Ethan's, Colin's, and Oscar's. All three were very happy with their new form, and found it very pleasant to share a body with two other men.
