When Sans telephoned home after dropping Azriel off, his face turned so blue from holding it in the entire time.
One glance down and he saw he was very hard. He changed out of the clothes to get a better grip on what he is going to do. He laid on his bed with the covers over just in case someone badge right on in. He then started to pump is dick, growing at the feeling. It made it better when he thought of Azriel as he pumped his dick, letting a few quite moans slip from his grasp.
He felt the build up and started to stroke hard until he came. He stopped to breath, he realized that was a bit intense then what he normally did. Then again this would be the first time he was in a relationship. He cleaned up a bit then fell asleep.
They hanged out a few times over the week and went an another date that month. On that date they both got drunk and cuddled on Azriel's bed. Both were very flustered in the morning but cuddled that morning anyways.
In 4 months they have developed their relationship. No Sex, yet, but sometimes they would help by either completing/degrading them, hands on work, or toys. But they talk about it, and finally did it. More of Azriel fucked Sans so hard he became pregnant after a few weeks. Sans became nervous about having a child, but he had a choice and wanted to keep them.
It was a matter of time before telling Azriel. So he man up and went to Azriel's house and to his room.
"Babe, I have something to tell you."
"Sure what is it?" Azriel was on his bed reading a book but gave his attention to his boyfriend.
"Promise not to leave after I tell you."
"Sans is something wrong?" Azriel became worried for his lover.
"Promise me that."
"I promise my master that I will not leave him."
"I....I am pregnant..."
"Really?!" Azriel sat up on the bed with a smile on his face. Sans nods to the goat boy who jumps up with excitement. "We are going to be parents!" He yelled and hugged his lover giving him kisses and very needed attention.
"You don't have to yell it."
"I don't care, you are my everything and this child will be our everything." Azriel got on his knees and hugged Sans and their child.
