Spike couldn't tell when exactly it was that Rarity passed out. It had been a few hours since they began. Half a day maybe? Maybe longer? He didn't know and couldn't tell. All he knew was that now his fuckhole was bloated, leaking cum and drool and no longer clenching around his dick when he pushed it in. "Damn, my balls are still so full. That's what you get for blueballing me!", the hilking beast of a dragon complained as he pulled his dick out of the unicorn lady, completely soaked in his seed.
"Uhm, hey~" Spike hadn't even noticed Sweetie Belle approaching from behind. The sound of clapping and squelching flesh was so loud he simply couldn't hear the steps. "I thought I'd get you something to drink, hig guy. But I see you're already done with... That~" Sweetie Belle was by no means intimidated by Spike's form, twisted and grown in size due to his desires, but she know a good guy like him wouldn't hurt her. At least not in a way she wouldn't like, she thought, smiling and biting her nail to the scene on display. Her body rocked side to side, showing off her jiggle jugs spilling over her spaghetti top.
The younger mare was still lost in fantasy when Spike grabbed her shoulder. Without as much time to gasp, Sweetie was already getting confronted by that colossal dick smearing seed on her face. Her mouth, nose and skin all got drenched by a mix of her sister's juices and the residue of Spike's potent seed lingering on his shaft. "Oh damn, this is do hot. How could Rarity ever deny him any of this?" Sweetie thought with the last bit of willpower the overwhelming musk left her with.
"I am NOT done!", Spike announced as he pushed Sweetie onto the bed. Soon she'd know exactly how her sister felt.
