Bottom's Up

The instant Sam took the pill, his cock immediately started to rise.

"Holy shit!" He said. "You guys weren't kidding." His libido skyrocketed as well. He started walking toward Shira, cock-first. He didn't know what had come over him...

"Yeah, baby," Shira said. "Momma's gonna take good care o' you." She took his cock in her hand and started stroking in a circular formation. "You have the biggest fuckin' dick I've ever seen on a white boy," she said staring down at it. "Especially for a newbie."

Sam's dick throbbed hard, and needed far more than a simple stroking. He spun Shira around and rubbed his thick fuckpiece between her butt cheeks.

"Ohhhhh," Shira said, swaying her hips from side to side, "I should've known. Everybody wants a piece of this ass." The jiggle from where slapped her ass vibrated Sam's huge cock, triggering an impulsive groan.

"Big boy," she continued, "if you wanna pump this asshole hard, we're going to need to lube you up first." Shira turned around, got on her knees, started slobbering all over the big dick in front of her. Sam grabbed the sides of her head and guided her, making sure that she kept a quick pace and stuffed his dick all the way down her throat, causing her to make a "Glug, Glug" sound as Sam's mushroom tip tickled her tonsils.

After a good ten minutes of throat fucking, Shira bucked her head to signal she was ready to fuck. Releasing his prize penis from her lips, she turned around on all fours and shot her ass up in the air, presenting Sam with his round prize. He lined his cock up, then slowly pushed downward into her ass. Once inside, Shira's ass gripped him like a vice. After just a few inches, he wasn't even sure he could fit any more dick inside her. Just when he was about to give up, though, Shira pushed back up on him with a loud groan.

"Gaaaaaawwwwwwwwddddddddddddd," she moaned as she slowly slid Sam's dick back out. "you have an aammmmmaaaazzzzzzziiiiiiiiinnnnnnngggggggg cocccccccckkkkkkkk!" Slowly, but surely she brought her ass up and down, pushing further inside with every stroke. Sam, dumbfounded, found his footing and began pushing his hips to match her movement. Each powerful thrust made Shira's butt cheeks quiver like someone dropped a pebble in the center of a fountain.

Shira, overcome with painful pleasure, lowered her head and focused on playing with her clit as Sam took control of her assfucking. He widened his stance and mounted her completely, plunging into her hard and fast.

As Shira quivered and came, all of her holes tightened. She knew Sam couldn't last inside her once she got off. "You gonna cum for me, baby?" She asked.

Sam didn't have time to respond. With one last, hard thrust, he released his new load deep into her ass.
