Jim pushes hard down on the air pump and both he and Alice gasp as air flows into the void of their bellies, but it starts to flush out from somewhere, taking the undeniable pleasure with it. "What happened, where is the air going? Alice asked, fearful of just what had happened. Alice suddenly starts shivering as a rush of air escapes her ass and vagina, the air from the pump had escaped. Jim had feel a similar experience, moaning as air filtered out in a stream from his penis as a small gust blew from his ass.
"Ok... That answers my question. *gasp*" Alice said as the pleasure from the rush subsided. Jim nodded his head as a slight tingle started to affect him, the tingle was directed at his ass and penis. Jim looked down and his jaw dropped in shock as he and Alice watched his penis slowly shrink into him, his testicles and sack having followed suit. Soon Jim had a flat surface that he gingerly touched, feeling flesh thankful as he reached towards his ass to see what the other tingle was. Feeling a flat surface his face looked at Alice in shock as they were too stunned to reply.
Then the tingle happened in Alice, electing a small moan from her as her vagina and ass fused into flatness, leaving smooth flesh behind along with Alice's rubber tail. "Well... That takes care of that problem." Jim said before giving a shallow chuckle. He had just lost his genitals and Alice as well, but he couldn't help be feel happy that the air now had nowhere to escape from.
Alice was having similar feeling, touching her smooth crotch. "Jim... Start pumping, I want to take my mind off this..." Alice said as she griped her air hose again, Jim nodding before placing his hand back on the pump, ready to push.
