A knock on the door

As he was almost finished killing the last zombie in the area Alex was distracted by a loud knock at him bedroom door.

"Come in" he said grinning and pausing the game.

Stella walked into the room, her hands gripping her stomach as her face was contorted in pain, "Help me" she said taking a few tentative steps inside his room; Alex immediately jumped up to his feet and guided her to his bed before going back and closing the door.

"What happened?" he asked thinking she must have gotten shot given the ammount of pain she was in.

"Cum..." she said as she winced again and grabbed her stomach harder.

"It's not supposed to be this strong!" he thought as he looked at all the outs he had before settling for the more amusing one.

"Stella, the lack of cum in your diet doesn't make you sick, but instead makes you incredibly horny but unable to cum until you taste my semen" he said, a smile growing on par with his cock.

Stella immediately jumped up to her feet, no longer holding her stomach, her face definitely more flushed than before.

"So, about my diet..." she started talking looking down at her feet sheepishly.

"Yes? What about it?" he replied playing naive.

"Are you free, like, right now? I have a lesson in half an hour." she asked blushing and becoming even redder than she was before.

"Sure!" said Alex sitting back down on his gaming chair, "You can start whenever you want".

"Can't you stand up next to the bed? So I can sit on the bed and don't have to kneel?" she asked.

"I'm a bit tired, sorry" he said picking up his phone and starting to record before switching to one of his games to remain inconspicuous.

"Damn it." he heard the girl say as she kneeled in front of his chair and put her hands on her knees, "Well? Aren't you gonna take it out?" she asked.

"You have to do all the work, or it won't sate your craving" he added as he surreptitiously point the camera to his crotch.

Stella sighed as she reached forward and undid his pants before puling them and his underwear down just enough to free his cock; she tried to remain impassible as she grabbed the tool in front of her and started to move her hand up and down the lenght, but her face betrayed as Alex saw her bite her lower lip as she pulled it out.

Her hand was soft and gentle on his cock, apparently knowing where to touch to get the most out of the interaction and get it over as quick as possible, and quickly Alex felt his climax approaching.

"I'm coming!" he warned, as Stella quickly jumped forward and held her mouth in front of his cock without touching it as rope after rope of his cum coated her tongue; the camera got the perfect angle as she closed her mouth and swirled the cum in her mouth before swallowing, and as her face scrunched up as she came on the spot Alex couldn't help but start to get another erection.

As Stella's eyes opened again she silently got up and ran out of the room without a word, leaving Alex to his game as he tucked himself back into his pants, satisfied for now.
