Twilight Sparkle and Spike where there house celebrating Spikes birthday. The party was coming to end and all the other pony's had returned home so after a few more hours of partying Spike said
"Well that was awesome but don't you think we should get some sleep"
Twilight walked over to him and gave him a seductive look.
"What are you doing?" said Spike in a rather worried voice
"Sit back Spike, your older now" said Twilight gently pushing Spike back into a chair, her voice was soft and seductive. Twilight put her face close to Spikes groin
"Come on Spike let it out" whispered Twilight. Spike could not hold it back anymore and his huge erect cock and huge balls emerged from under his scales. Twilight gasped and Spike closed his eyes wondering whether he was dreaming or not. Twilight rapped her mouth around Spikes cock and began to suck, Spike moved around on the chair in pleasure as Twilight worked her tongue up and down Spike's cock and after a few minutes Spike said
"I..I'm gonna.." Suddenly Twilight stopped and she pulled Spikes cock out of her mouth.
"I want to mount you Spiky" said Twilight as she began to climb up onto Spike
"but Twilight! we don't have any condoms!" said Spike but Twilight was already slipping down onto him and as she lifted her self up and down she said
"I'm pretty sure a dragon can't get a pony pregnant and I'll just get off before your done" Spike began to move himself up and down with Twilight and Twilight began to moan in pleasure. Spike's cock pushed deep inside of Twilight and he entered her womb, Spike felt a large egg begin to move thru his shaft
"Twilight! I'm gonna" yelled Spike as he tried to lift Twilight off him
"No Spike I'm not done" Said Twilight and she pushed her self down onto him making Spikes cock erupt deep inside her. Twilight had multiple orgasms and she fell back onto the floor, her belly was gurgling and distended. Twilight passed out and Spike passed out in the chair.
As Twilight slept something began to move inside her.
