Enjin

Enjin felt the first wave of his heat coming when he was hanging out with you

He had been playing games with you and you headed to the bathroom. He sat still for a little while. Just drinking some beer and waiting for you to come back. But he smelled something. . . It smelled utterly delicious, and he sniffed around before finding it was your spot. He noticed you weren't coming back yet so he lay down in your scent.

He almost started touching himself before hearing your voice. He sat up immediately and jolted up, immediately starting the game again. Starting without you. He let out a teasing joke but the tips of his ears were red. Giving him away. He was hoping you didn't notice

The second time was when he was out eating with you, you had just finished your rut, meaning your scent was fading but way stronger. He noticed when you stretched. His nostrils flared and he smelled your sweet scent. His underwear was getting wet. And man he needs to head out. He quickly dismissed himself and went to the restroom.

He pulled down his pants and saw a wet spot, sticky and wet with slick. He hated this. He slammed his head in the wall and let out a groan.

The third time, which was current time. You caught him. He was in full heat. He had locked himself in a room and made a nest for himself. He sat in bed and watched TV all day, he always felt a nagging feeling in the bottom of his stomach. He grew restless and put everything down and turned everything off. He slowly reached down into his pants and flicked his clit. He bit his lip, letting out a small whine. He circled around it and felt more slick leak out and his hips buck up

What he didn't notice.

Was that you were in the doorway, about to ask him why he had taken the day off

Seems like you knew the answer
