It had been a few days and Martin was still feeling the effect of having Mark inside of him. Martin and Mark were still texting and found that Mark had a bit of a string of night shifts and classes, but an opening was coming up that evening.
One thing that Martin had realized is that he had somehow gained 15 pounds since meeting Mark. Besides the big meal at the buffet with Mark, Martin had been eating pretty much at a normal pace. Yet 15 pounds had shown up, all in his gut. Mark had noticed his shirts were straining a bit more and an off thought made him worry that Mark had impregnated him.
"As if that could ever happen," Martin said out loud," This is real life, men don't get pregnant."
But they can catch other STDs, so Martin decide to go to the doctor to get a check up.
"What can I do for you, Martin?" asked the doctor after Martin had been waiting in the office for what felt like an hour.
"I need an STD check please," Martin polietly asked.
"Sure," the doctor agreed and walked over to the desk and started taking out a few supplies," Any reason for the check? I believe you just had one a month ago."
"A condom broke," Martin answered with a sigh.
"Good for you to come for a check," the doctor smiled and readied the needle.
The doctor took a little blood and did a swob of Martin's butt and sent the samples to the lab in the building.
"We should have the results in a couple of minutes," the doctor smiled," Anything else I can do for you?"
"Actually.. yes.." Martin said and saw the ultrasound device," Can you check me with that?"
"Sure," the doctor said and started up the machine and spread the clear goop across Martin's exposed belly.
After a few minutes of looking at the weird images Martin and the doctor were convinced that there were no babies inside of him. A few minutes later Martin's STD test came back all negative.
"Sounds like that boy was telling the truth and he's all clean," the doctor said with a smile," But still play safe now."
"I will," Martin said getting to his feet and sighing with relief.
That night Mark showed up at Martin's door with two dozen doughnuts and an XL pizza. Martin was in love. Martin sat down at the kitchen table while Mark sat on the table with the pizza in his lap and slowly hand fed Martin each piece. When Martin was thirsty Mark was there with a cup with a straw of pop. Martin was in heaven. When one of Mark's hands were free they were rubbing Martin's soft moobs or belly.
Martin didn't take long before the pizza was devoured and was on to the doughnuts.
"Damn, you eat life a pig," Mark commented seeing Martin devour the doughnuts and getting chocolate and filling around his mouth.
"Oink, oink," Martin teased.
"I know," Mark said and undid his shorts and slipped off his shorts and underwear to reveal his throbbing hard on," How about you eat the doughnuts off my dick."
Martin's eyes widened and Mark started to place doughnuts on his dick. Martin leaned forward and started to eat the doughnuts off of Mark's dick while giving Mark's dick a blow job. Once the first set was done Martin came back up for a drink and Mark refilled the doughnuts.
It didn't take long before the doughnuts were down and Martin was giving Mark a full on blow job. Mark's dick tastes so sweat to Martin and the precum was delicious to him as well. Martin did his best to suck, lick and pleasure Mark and he knew it was working as he heard Martin moan loudly while holding Martin's hair.
"Oh god fat boy, your mouth is just as good as your fat expanding ass!" Mark moaned," I want to keep fucking you until you're too fat to... to.. move and you're nothing but.. an... non stop eating machine... and... and... oH God!"
With that Martin felt the hot squirt come from Mark's dick as it unloaded deep in Martin's throat.
Martin swallowed and sucked the last of Mark's load from his dick.
"Jesus Christ fat boy," Mark said breathing deeply," You're amazing."
"So are you," Martin smiled," Do you want to spend the night?"
"Damn right I do," Mark said and slid off the table and wrapped his arms around Martin's gut which gurgled.
When does Martin's next grow happen?
