Hearing Rob talk about the possibility of sex triggered something deep within Luke's stomach. It was like the possibility of sex being the thing to fix all of this was beginning to break him down, overcoming all rational thought. His pussy ached and began to drip down his thighs as he tried his best to fight his perverted urges. God, am I seriously considering having sex right now? He thought to himself, I've been thinking about it all day, it's becoming impossible to resist... Surely it's worth a shot, right? Y'know, to reverse the merge of course...

"Look, at this point I'm willing to try anything if it helps. I know it's weird but-OH!" Luke gasped in surprise as he finally slithered a hand up his own skirt and brushed against his clitoris, pleasurable alien sensations filling his body. Hormones were already starting to fill his female brain with fantasies of men's erect cocks. Looking around to make sure nobody was watching, he turned at Rob. "Okay, we can fuck. But only because we're trying to change me back. And we never bring this up again." Rob nodded furiously as the two searched for a place with enough privacy to try and sate their impulses.

Finally finding a spot behind an old greenhouse, Luke took off his shirt and showed off his big tits, struggling to unhook his tight white bra over his shoulders. "Let me handle it..." Rob said, reaching forward and letting his friend's boobs bounce free with one motion.

Taking his soft breasts in his hands, fingers rubbing his dark nipples, Luke laid back on the ground and hiked up his skirt. "Promise me you'll start off gentle... and then take me like the whore that I am now." He was hoping to encourage Rob to take control, but even he was surprised when without hesitation the boy spread his partner's thighs and thrusted his hardening cock deep inside. Bliss filled Luke's mind as he moaned like a bitch in heat when Rob's impressively thick 9-inch beast swelled to its full size, stretching the teenage girl's tight pussy to the limit. At first Luke wanted to beg him to stop, but as his breasts bounced and his eyes rolled into the back of his head in otherworldly ecstasy, his mind quickly acclimatized to his role as a sexy, fuckable teenage slut. He was screaming, but he didn't care who heard - all that mattered was each moment of nirvana.

Just two minutes passed until Luke felt Rob fill his pussy with spurts of hot, sticky cum after just a couple of minutes. Both collapsing onto the ground panting, the boy-turned-girl took a minute to process his complex emotions in the afterglow before he spoke. "Wow, that was quick. Obviously you're a virgin." Luke teased, trying to ignore the semen still leaking out between his legs, feeling ashamed of what he had done to Erika's body.

"No fair! You know Erika's hot and your pussy was amazing! Besides, your first time having sex was as a girl!" Rob replied.

"Whatever, dude." Luke giggled cutely, still optimistic about their latest method. "Maybe next time you can try to last long enough to actually bring me to orgasm and see if that works. That did feel really good though... Are you able to come over tonight? You can sneak in through Erika's bedroom window... Please?"
