Erika could hear the bell ring, signaling the start of second period, and ensuring that Erika wouldn't be disturbed, at least for a little while.
*Sniff*
"What...What the hell was that?" Erika asked herself as she wiped her tears from her eyes. She rolled over onto her back and looked down toward her pussy as the tingling grew stronger.
"What's happenAHH!" Erika arched her back as a waves of orgasmic pleasure surged through her body. Erika clenched her fists and moaned. "AHHH....AHHHHHH....sigh......" Then, the pleasure faded, almost as quickly as it began.
"What...the HELL was that!?" She said to herself as she stood, and proceeded to undress from the waist down. She let her skirt, then her panties, fall to her feet. From her pussy, she could see her own juices, and something else, drip.
"Is that...semen?!" She exclaimed. Suddenly, she could see her belly push out, just a little.
"Oh, no...not that!" Her belly continued to push out, hastening with every second. She already looked at least 3 months pregnant.
"Ooooh...this feels soooo...strange...Oh! Was that a kick?" Her belly grew and grew. Now, not even a minute after it started expanding, the growth slowed to a halt as Erika became 9 months pregnant, and her water broke.
