Jennifer was still huffing and puffing, her tits still smashed into Sam's face. The orgasms she just experienced were some of the strongest she's ever had. Her body was still aflame with desire but she noticed that her muscles were starting to get sore. As she sat in Sam's lap, still fully impaled on his wonderful dick, her mind went back and relived the past thirty minutes.
She remembered how skeptical she was about the sexy dice game she brought home. Jennifer remembered the electrical thrill she received when first holding the die and how nerve-wracking the chills were.
Her eyes glazed over as she continued remembering the raw sexual lust that came over her as she went to town on Sam's dick. She was starting to get a little wet again when she realized that the tingling feeling from earlier was back and felt stronger than before.
"Sam, are you still hard?" she inquired.
"Yeah, your pussy squeezed me so hard I thought my dick was going to fall off. I couldn't get off because of your grip," he stated in a slightly irritated tone.
"Oh shit, I'm sorry. Let me take care of my big man," she said in a sultry voice.
Jennifer wasn't sure what was going on with her. She loved sex with Sam but tonight she felt like a demon-possessed. Although she knew Sam's stamina didn't survive past two orgasms, tonight was not over. She slowly tried to lift herself off her lover when the tingling in her pussy reminded her something was wrong.
She groaned, "Ughhhhh, Sam if I didn't know any better I'd say you got bigger. I can feel you penetrating me fully, even in spots you've never reached before."
Jennifer kept wiggling to try to get off this massive pillar insider of her, but nothing was working. Sam was quiet for a few seconds then spoke up, "I think I know what you mean, just after you finished cumming all over me I felt a warm tingle in my dick, almost like it was stretching."
The two of them froze. Any progress Jennifer had made was erased as the mention of the tingling sensation caused her to panic and fall back into Sam's lap. Neither one had mentioned the tingling sensation out loud to the other.
"When did you first start having the tingling sensation?" Inquired Jennifer.
Sam pondered her question for a second. All at once, the memories of what happened came flooding back to him. He quickly blurted, "It started the second I touched the male die. I was a little tipsy so I thought it was my mind playing tricks on me, but if you've felt something similar then there is definitely something weird with this game."
Jennifer nodded in agreement and started to notice that the shock of their realization was starting to panic Sam. His rock-hard dick was starting to deflate and retreat back towards the entrance of her love tunnel. Jennifer was a mixture of both glad and sad that Sam's monster was diminishing. She'd never felt that full before but was also starting to get anxious that she wouldn't be able to pull off of him.
Once free, the two lovers looked towards their genitals and could already see changes. Not quite at full mass, Sam's dick had not only grown longer by a few inches, but his girth exploded with growth and was now the size of a soda can.
Jennifer gulped with lust as she saw that huge dick flop around. She never would have expected something that big to fit inside her. Glancing around herself for changes, she was disappointed to see that her ass had shrunk down a bit from its former glory that she had just gained minutes before.
The wheels started to turn in Jennifer's mind. Testing her theory, she reached down and stuck her index and middle fingers inside her slippery snatch.
"Ooooh shit! No wonder I couldn't get off your fat dick Sam, my vagina seems to have shrunk," Jen mentioned with panic in her voice.
Sam's eyes grew wide and said, "No kidding? I thought maybe I was still hallucinating but you felt impossibly tight at the end there, it could explain that tight grip you had on my third leg here."
Jennifer couldn't help but give a nervous chuckle and casually said, "Sam, your dick isn't big enough to call it a third leg. However, it does look bigger, if I had to guess it looks like it taps out at 9 inches. My vagina should've still been able to still handle it, but I definitely feel smaller."
Jennifer got up from her spot on the couch and was scanning for the packaging that the mysterious game came in. As she was looking around the coffee table a small slip of white paper caught her attention. She bent over at the hip and gave Sam a front-row view of her new shapely ass. Jennifer seemed a bit puzzled, she was never this forward before.
Without hesitation, Sam inched himself up to the edge of the couch, grabbed both of Jen's ass cheeks, and dove headfirst into her pussy. He wasn't sure what was going on with him, it just felt like the right thing to do.
Completely caught off-guard, Jennifer quickly put both hands on the coffee table to help stabilize her balance and squeals, "Ohhhhhh shit Sam, you've never done that before!"
Sam continued licking in earnest and in acknowledgment of what she said, began groping her ass with wild abandonment. With her smaller vagina, Sam's tongue felt amazing as it probed around her clit and deeply dove into the shallow depths of her tight pussy. Jennifer's mind went blank and forgot all about the new stresses of what was happening to them.
After a few minutes of blissful licking from her stud, she repositioned her legs and arched her back so Sam could get a better angle to mash his face against her. She timed his rhythm and began grinding her pussy in time with Sam's face. She was so entranced by her flaming desires that didn't notice she bumped the table. The die both jiggled around and landed on new sides. The female die landed on boobs and the male die landed on muscles.
Before she could try to piece together what was happening, Sam pulled another surprise on her. His neck was starting to ache as he was leaning so far forward for so long on the couch. Sam decided to go for broke and moved upwards to her puckered hole.
"Ssssssshit Sam I never thought you were into that," hissed Jennifer through clenched teeth.
Sam wasn't in control of his body anymore and said between licks, "I'm not... but something... about this new ass... has got.... both of my.... heads intrigued."
As the last word ringed through Jennifer's ears, the tingling sensations came back, but this time it hit her through her chest. With the constant attention on her erogenous zones and the new sensations from the game, she was overstimulated. She reached a hand back and forced Sam's head further into her asshole.
