Narrator's POV
Today was Cartman's 18th birthday, being the youngest of the four boys, he was the last one to turn 18.
After the party cleared out, he decided to take a nap.
He woke up around an hour later and looked at the stairs.
he goes up to his room. On the stairs, he sees Heidi's signature hat, green jacket and dark green pants. Further up, he sees her shirt lying on the ground, her panties outside the door and her bra hanging on the doorknob outside his room. Upon opening the door, he notices several more things: a bottle of lubricant, a condom packet, and a can of whipped cream. Also, Heidi is lying on his bed naked, her legs divided and her breasts perked, with the nipples saying 'Touch Me'.
"So Heidi, what's my present?" Cartman asked.
"Me." She replied.
Cartman stripped naked: he has begun to lose weight and develop muscles, so he's not as fat as he used to be, in large part to his secret life as The Coon. Another part because he was tired of being called fat. He walked over to Heidi and they kissed.
"So, how should we start?"
"Eric, get the whipped cream."
Cartman picked up the can.
"Spray it on me."
"Okay, where?"
"Here, *Points to her breasts*, here, *Points to her belly button* and here. *Points to her vagina, which has no hair on it*."
Cartman grinned and began spraying the cream on the said areas.
*Under her breath* "Oh god, that's cold!"
Cartman finishes; he puts the can down and moves his face in. He sticks his tongue out, and licks her left mound. Heidi shudders and moans in pleasure.
Once the left boob was free of cream, Cartman moved to the one on the right. Heidi moaned again. Once that was taken care of, he began sucking on it, while pinching the other nipple with his left hand. He trailed his tongue down to her belly button, and licked off more cream.
"That tickles, Eric." Heidi said while giggling.
Cartman finishes licking the cream from her belly button; he moves further down to her vagina, and licks off the last of the cream.
"Oh god, that feels good." Heidi said whilst taking in a deep breath.
Once all the cream had gone, Cartman's tongue penetrated her vagina and he started flicking his tongue in and out, eating her out. Heidi's mind was lost in a sea of lust.
"Oh God! I'm cumming-"
She blew her load onto his face. Cartman seductively licked it off.
"Aren't we gonna change positions?" Cartman asked.
"Let's see what you're packing down there."
Cartman lay on his bed, as Heidi approached his now more visible dick.
"Golly, It's bigger than before."
She sucked on it. Cartman hollered in pleasure.
"Oh Heidi! Yes! Yes! Fucking Yes! I'm gonna…. Gonna-"
He blew is load all the way down her throat. Heidi swallowed it up.
"Oh my god Eric, it tastes like candy."
"Thanks Babe. Now, what should I wear first? The condom or the lube?"
"The lube." She responded.
Cartman opened the lube bottle. He poured some onto his hand and rubbed vigorously over his dick. Heidi turned her back to him, and teasingly shook her nice, round bottom in his face.
"Now Heidi. I, Dr. Eric, am going to give you a prostate exam."
He stuck two lubed fingers up her butthole. He pulled them out.
"Okay, now, are your buns ready for my hot dog?"
"Yep."
Cartman stuck his cock up Heidi's butthole, and began fucking her like a mounted dog. 2 minutes later, Cartman's moans got louder and he was fucking her faster, an indication of what was to cum.
"Here I cum-"
Cartman blew it into her butt. Heidi slumped down, as sizzling hot, creamy cum drizzled out of Cartman's dick and onto his bed. Cartman recovered quickly from his orgasm, and cheekily pinched her bum.
"Now for the grand finale." Heidi said.
She turned over and spread her legs apart, allowing Cartman the honour of seeing her clean-shaven pussy.
"Right; the condom."
He ripped open the packet and put it on. Then, got on top of his girlfriend, who put her arms behind her head, as Cartman kissed her boobs and entered her.
"I'm so full."
Slowly, Cartman began to fuck her. Heidi's tight walls coiled around his hard manhood.
"Damn, you're tight." Cartman said.
"Could you go faster please?" Heidi asked.
Cartman began thrusting faster, until he was fucking her with wild animal ferocity, and Heidi was loving it. Outside, Cartman's mom was going to bed, when she stopped to pick up Heidi's clothes, and take them down to the laundry.
"I'm cumming! Hold onto me tight!"
With one final thrust of his dick, he was done. And Heidi was panting a lot, like she just ran a marathon on a summer day. Cartman shifted until he pulled out of her. He took the condom off and threw it into the trash can, then lay down beside Heidi.
"That was Awesome!" Cartman excitedly yelled.
"So awesome." Heidi repeated.
"That was the best birthday present ever. I love you Heidi."
"I love you to Eric. And Happy Birthday."
"Can't wait until we finish school, so we can have our own home and get married.
"Me to."
Cartman turned out the light, then he and Heidi cuddled up to each other and drifted off to sleep.
"Uh Eric, are you touching my butt?"
"Uh, yes?"
"Oh you."
The next day, it was a school day. Cartman and Heidi met up with Stan, Kyle, Kenny, Butters, Wendy, Lola, and Bebe at the bus stop. However, they were struggling to walk, and Cartman nearly fell over onto his front. Heidi even had a hickey on her neck.
"Well, someone got action last night." Kenny said, noticing the hickey on her neck.
"Heidi, you and Cartman had sex?" Wendy asked.
"Yes. He's like a wild animal in bed. Does it matter if you and Stan did before me?"
"Well, Kyle and I did it before Stan and Wendy." Bebe explained.
"Well, the point is, we got laid."
"So ladies, how does having a penis in your vagina feel?" Butters nervously asked.
"We're not telling you Butters. You just have to experience it firsthand." Bebe said.
"Yeah Butters, I'll tell you how it feels for a guy: fucking amazing!" Stan told, making Kyle and Kenny laugh.
"Okay, but who am I going to try it with?"
"Hm, I don't really know actually. Just wait for a girl to come your way, then, do the routine." Kenny explained.
The End.
