Erica proves her control over you

"See girls? I told you that you'd like my surprise!" Kelly, clearly the most ****, chimes in with "God, what a pretty cock..." The other girls murmur in agreement. Another one asks "And she's stuck... turned on like that? Permanently?" Erica nods. "Mmhmm. Until I turn it off with this..." she holds up her phone.

"Bullshit," a red-haired girl speaks up. "You guys are pulling some prank on us. There's no way you can control her dick with your phone." You pre-emptively shiver as Erica grins mischievously. "Oh...?" she replies. Without another word, she starts tapping on her phone. A painful pulse wracks your groin and you watch in horror as your dick grows a couple of inches. What was once a proud 7-incher is now easier 10 or 11 inches. You groan as your dick grows and breathe heavily as it finishes, humping the air desperately. The transformation did nothing to help your predicament; in fact, it seemed to double the sensation as your dick becomes swollen and red. You can't help from grabbing it with both hands and sinking to your knees. "Ung please... let me cum..."

The redhead sits back in shock. "Man, fuck me sideways... I guess it's real!" Erica grins again. "Oh I'm not finished yet..."
