Dib now held a leash in his hand. “Down boy.” He said. Zim blushed as he lied down on the bed. He bent over, Dib placed the cat-bell collar on him and the leash too. Zim blushed. Dib then yanked off his lace panties, which were drenched. “Awe, someone can’t get his mind off my strap.” Dib teased. Zim let out a grumble. He got wetter once Dib said that, his alien dick harder.
Zim let out a loud whimpering noise, just the sound of it made Dib’s t-dick hard.
Dib fetched his strap, Zim liked how Dib could switch out the sizes for it. But today… he wanted a big one. “Please Dib-worm… get me the biggest strap you have…” He begged, whimpering. “Awe, someone’s desperate.” Dib teased as he fetched his eight inch strap. Dib put on the harness, then before he knew it, his strap was up in Zim’s alien cunt, tugging on the leash with his hand.
Zim let out a loud moan as Dib pinned him to the bed, on his stomach. “Good boy Zim.” Dib remarked, “So… big..” Zim moaned. He needed that. Dib began to thrust deeper and deeper into Zim’s cunt, he then placed his hands underneath Zim’s shirt. He began to touch his nipples. “Oh Dib…” He groaned. “Yeah, I know you like having me play with your freaky alien nipples, you little whore.” Dib commented, affectionately. Zim felt like he might come if Dib called him a slut or whore one time. “You’re such a good little slut for me, I love it.” Dib remarked, continuing to play with nipples first two nipples, flicking them his fingers. Before Zim knew it, neon pink come spirited out his cunt and dick. “Good boy Zim.” Dib whispered with a smirk.
“Please Dib… keep going!” Zim begged. He tugged on the leash some. “I will. You’ve been a good little slut.” Dib assured him softly, before latching his mouth onto Zim’s neck, attempting to give him a hickey. Zim moaned Dib’s name while he did so. “Oh my… are you giving me a hickey?” Zim asked quietly. Dib then let go once he was satisfied. “Yes, how else am i supposed to show others that you’re mine?” Dib finally answered. He then began to thrust faster and harder into Zim. “I’m going to fuck a baby into you Zim.” Dib smirked, continuing to pin Zim. “Please Dib-love! Fill me with your hideous human spawn.” Zim begged in whiny, clearly desperate manner. “Hm… I’ll have to think about that.” Dib replied in a smug manner, thrusting harder into Zim.
“Make me a Papa! Please!” Zim begged, “I can try. You’d look so hot and adorable all knocked up with our alien-human babies.” Dib remarked softly, loving caressing Zim’s ass. Before Zim knew it, he came again. “I think somebody wants me to shove a vibrator up his fat ass.” Dib remarked, snickering. “Please! I do!” Zim confirmed. Dib chuckled. He then grabbed the vibrator after pulling out of Zim once more. Soon enough, his strap was once again deep inside Zim’s alien cunt and his vibrator was nicely inside of Zim’s asshole.
Dib continued to fuck Zim and play with his nipples and gave him a few more hickeys, telling him how he’d make such a good and cute Papa. “Dib-worm… I think I’m done.” He said. Dib immediately pulled out of him and turned off the vibrator and pulled it out too. He took off the strap harness as well. He also took the leash off Zim and the collar too.
He then gently picked up Zim. They now were both naked under the sheets. Zim let out purrs. “Thank you, my Dib.” Zim smiled. “No problem, my little slut.” Dib affectionately replied, then kissing Zim’s cheek. Zim then nuzzled him more, and soon they both feel asleep, in each others embrace.
