After a minute of catching her breath, Erika pulled her panties to look. The hard pole was back to being a soft tube, and it was covered in sticky goo. It also looked a little bigger than before. Maybe two and a half inch long now.
She stood up with her wet panties sticking to the sac-thing between her legs and the tube sticking outside on the front, when someone knocked on the door and barged in her room. In a hurry, she let her skirt fall back over her crotch and opened a new tab to hide the naked bodies from the computer screen.
"Erika!" It was her mother. "I'll be going out tonight and won't be back until very late, so be sure to keep the doors locked and keep Sassy inside with you. There are leftovers in the fridge for when you're hungry".
Erika was trying her best to pay attention and look normal, but all she could think about was the fleshy thing dangling outside her panties under her skirt.
"Y-yes mom, I'm not a baby anymore! I can take care of myself..." she replied, flustered. She pulled on her skirt, trying to hide the small budge.
"Well, good then. Don't stay up too late, you don't want to be exhausted for school tomorrow" her mom said as she left the room.
Erika closed the door and lifted her skirt again. The tube was still there, poking out of her wet underwear. She pulled the panties down to grab another pair, stuffing her package inside after she had wiped herself clean with a tissue.
Touching herself in the area still felt nice, and the thing started to harden into a pole again, tenting the clean panties further than before. Erika covered the sight with her skirt but the tent was still visible. She whimpered.
