Erika opened the door next to her, which happened to be Cole's bedroom. Melissa wouldn't think of looking there. She closed the door quietly behind her, hearing the muffled steps of Melissa walk in the corridor - to the bathroom maybe.
Letting out a sigh of relief, Erika's eyes looked for Cole. The scent of female fluids floating in the room filled Erika's lungs - he must have masturbated for hours with his female form. She saw him passed out on his bed, naked, a leg hanging out of the bedframe.
Erika watched him asleep. The effect of ingesting the goo was fading, and the breasts he had grown were reduced to two small puffy mounds heaving along his irregular breath. Between his legs, his sack was pushing out of his lips and his growing clitoris, about the size of a thumb by now, was raised.
She heard him moan in his sleep. Erika drew closer to the bed. A bead of fluids pearled out of the tip of Cole's dicklet.
If only she could ingest some of the goo, her body would revert back to female - temporarily maybe, but at least long enough to avoid discovery while her friends were still around. She was desperate for a solution.
She walked to the bed and kneeled down near Cole's exposed crotch, her face closing in. His clitoris really resembled more a miniature penis by the minute, lenghtening slowly in his sleep.
Erika gently wrapped her lips around the head, sucking on the pre. Cole's penis twitched faintly and hardened against her tongue; it started swelling more quickly and emitted another ooze of pre.
The taste was strangely intoxicating, and Erika felt her one-incher getting hard already. Furious, she increased her succion and slid a hand against her nightgown to press her tiny penis back into her groin. How could she still be horny, so soon?
Cole's breathing became louder as Erika was waking him up.
"What... what's happening?" Cole asked drowsily, his voice somehow still pretty feminine.
Erika hold his small but growing dick with her free hand and whispered: "there's no time to explain, but I really need your goo right now! Melissa could find out about everything... I already came earlier, you have to help!"
"What... how... ooh..." Cole moaned as growth spasms animated his swelling cock, Erika already back to sucking him. His balls pushed out of his body, filling with semen and inflating visibly under Erika's face. At the base of his penis, a knot began to grow, pulling his foreskin all the way back.
Erika wouldn't let her own erection spring out. She was pinching her foreskin firmly, almost hurting herself, and keeping her small erection burried inside her groin. Her licking and sucking became more determined as she felt Cole's penis becoming pointier in her mouth, and his balls getting furry and tightening against his body. He was close.
"Aah... Er... Erika!" he moaned in a girly voice and his member thrust into Erika's mouth to its full lenth, overflowing with semen. The huge cock almost slipped away from her lips, too big to fit.
Gulping down as best as she could was all Erika could do as she was holding Cole's canine cock with both hands now, letting her painful erection spring free. Almost immediately though the goo started affecting her, and she felt her hard-on die down as her penis shrank into her body.
Touching her groin with one hand as she was licking Cole's length, her fingers could recognize a perfectly female slit. Cole propped himself on his elbows and stared down at Erika while his orgasm was dying down; her face was splattered with cum.
On that instant, Cole's bedroom's door swung open.
