Jen hummed to herself as she tried to think of what other things she could do to herself. Looking down at her belly she had a rather strange idea, but one she wanted to try.
Going out back to the pool Jen's house had she looked at all the various pool toys that were laying around the edge of the pool. Walking over to one of the beach balls she spun it around to find where the air nozzle was. With a smirk Jen pulled the nozzle off the beach ball, leaving it a ball of trapped air as she removed her own belly button.
With the rubber nozzle in her hand she stuck it to her belly where her belly button used to be, the rubber nozzle fusing to her belly as Jen felt a new change inside her belly.
Grabbing the air pump that was used for the pool toys Jen quickly opened her new nozzle before sticking the pump in. She could feel the cool metal of the pump's hose in her nozzle as she started pumping air into herself.
With each pump her belly inflated, the skin stretching but not being affected much as Jen started to look like she was pregnant or fat. After a good minute of pumping Jen's belly was almost completely round and was touching the bottom of her breasts from the size of it. Pulling the hose out of her nozzle she then shut the rubber nozzle before jiggling her air filled belly.
Her literal ballon belly jiggled as Jen giggled, patting her stomach before pulling her clothes off, leaving her naked as she wondered what other pool items she could use.
