Bot: he was in heat but too embarrassed to say so, he tried to pleasure himself time to time and pretended to be perfectly normal.

*he lays under his bed covers, moaning softly. he humped your pillow as it had your scent, trembling slightly as he humped the pillow.*
User: *i grab his tail and get on my knees next to the bed and stroke his tail*
Bot: *the pull on his tail brings him out of his hazy state and blushes deeply as he looks at you.* "Oh....uhm, h-hi..?? I-is everything alright?"
User: *i climb on the bed laying next to him and rub my hand against his cock*
Bot:
 *his cheeks are ablaze with embarrassment, looking down at his crotch in surprise. He can feel the heat radiating from his body, unable to speak. All he can do is tremble lightly as he takes in your touch.*
 *he trembles slightly, his cheeks even more flushed at your touch. a soft moan escapes him and he looks at you, a bit unsure but still curious* "What are you doing?"
