Alicia comes clean!

"Max, wait!" cried Alicia suddenly, "you can't cum inside Blake!"

"Huh?" Max grunted. He barely heard what she said as he was so focused on the pleasure of fucking you. What the fuck was Alicia doing!?

"Why not?" said Simone, "It's not like she's the first girl to get creampied this evening."

"Yeah!" agreed Kay, her hand on her own sperm-filled pussy, "you even let Max cum in you." She looked back over to you and Max, "I think he should cum in her. I bet she'll love it."

"Oh god yes!" you moan in response to Kay's words.

"No, you don't understand!" Alicia was frantic, "she's not really my cousin! She's... he's... that's Blake! that's OUR Blake!"

"What?!?" Liz nearly spat out her wine.

Fuck! Why was Alicia doing this? She's blowing your cover and right when Max was about to fill you with his seed! "Max, cum in me, please!" you cried. Max grunted in confusion and pleasure but he kept fucking you.

"She doesn't know what she's saying," Alicia said, "Look, Blake came to me this morning. He said he wanted to come to this sleepover but he didn't think any guys would be allowed in! So we got one of those X-Change pills so he could sneak in as a girl!"

"Oh, I've heard of those!" Kay perked up. She checked out your body as Max continued thrusting into you. "Damn! Those pills really work!"

"Yeah, I tried one once," said Simone, "I was curious what it was like to be a man. It worked great! And I was HOT."

"What!? Get the fuck out of here!" Kay shot Simone an incredulous stare.

"Guys! This is serious! Listen!" Alicia protested, "They were out of regular X-Change pills so Blake took a Breeder pill! It turned him into a girl for 72 hours, but he's super fertile, and if he gets pregnant he'll be a woman forever!"

"Holy shit." said Simone.

"Gnnugh," Max slowed his thrusting and looked you in the face, "Blake, is this true?"

You looked up at your best friend. "Yes Max, it's true," you said. You wrapped your legs around him and pulled him further into you as pleasure enveloped your entire being. "But this is what I want, Max. Fucking you is the best thing I've ever felt and I want you to keep fucking me, and I want so bad to feel you cum inside me!"

"Max!" cried Alicia, "she's only saying that because the Breeder pill is making her try to get pregnant! The pharmacist warned him about that side effect but he figured it wouldn't be problem since there weren't supposed to be any boys here."

"I... I..." Max shook his head as he started fucking you again, slowly. He was clearly trying to wrestle what Alicia was saying with the sheer pleasure he felt from fucking you.

You looked him straight in the eyes as you began thrusting back. "Doesn't it feel good to fuck me Max?" you said, pulling him in with your legs as you wrapped your arms around him and pressed your body close. You whispered into his ear, "if you knock me up right now I'll let you fuck me whenever you want."

"Blake," Liz looked at you, her face awash with confusion, "is this really what you want?"

"Yeeessssss..." was all you could get out as the pleasure of Max fucking you overwhelmed you again. Of course this what you want! You wanted desperately to get knocked up, and sure, it was probably the Breeder pill that was making you feel that way, but it was more than that now. You didn't just want to have a baby, you wanted to have Max's baby. You two had been through so much together already, best friends through thick and thin. Motherhood was the natural and obvious next step in your journey with Max.

"I... don't... I... don't... know..." Max panted as his thrusting became more intense. More deliberate. "I... don't... I... Ohhh fuuuucckk..."

Spurt. A sudden wave of sheer orgasmic bliss washed over you as you felt the first rope of cum shoot into you. It felt like it was shooting through your entire body.

Spurt. A second shot of sperm flowed into you. Contentment. Everything is right in the world.

Spurt. Spurt. It was like you could feel every bit of Max's seed as it poured into you. Filling you. Completing you.

Spurt. Spurt. Max's cum merged with your own as your vagina filled beyond capacity. Just as you felt you were merging with Max himself as you pulled him to you as waves of orgasm flowed over you like nothing you had ever felt before.

"Shit." Alicia said.

"Oh my." said Kay.

"Well then," said Simone.

"Oh. So. Hot." gasped Sam, breathlessly. The other girls turned around and glared at her. "What? I came like three times watching that."

Max's thrusts slowed as he finished his orgasm. The waves of pleasure flowing through you felt like they would never end, but gradually your orgasm started to subside. However, it left something with you. Deep in your core was a warm feeling, a reassuring knowledge, that Max had just impregnated you, and that this body was now yours forever. You ran your hands down your thighs, over your hips, up over your flat (but not flat for long) belly, and cupped your breasts. You smiled.
