Adultery My Mom & the exchange student

[Penetration]

　　Li Xiaojun opened his eyes after I stood up. The moment he saw my erection, the little slut looked at me resentfully, her eyes even more charming. 
　　"Give me a mouthful..." I imitated Sam and smiled lustfully. To my surprise, Li Xiaojun stood up quickly, opened his red mouth and took my glans into his mouth. 
　　"Ah..." I breathed out comfortably. Li Xiaojun's body felt hot because of me. She hugged my thighs with both hands and opened her mouth to take all of my penis into her mouth. The tip of her nose was close to mine. There is some pubic hair on the lower abdomen. 
　　"Ouch..." Feeling the warmth of the penis in Li Xiaojun's mouth and the tip of the glans pushing into his throat, I immediately had the urge to ejaculate. 
　　"Huh... ok, get up, I want to fuck you!" I held her head with both hands and moved it away. My penis was suddenly pulled out of Li Xiaojun's mouth, which was still sucking greedily. Lustful saliva came from the corner of Li Xiaojun's mouth. It dripped onto the ground, and the glans was covered with the thick saliva from her throat. 
　　"Um...hum..." Li Xiaojun pretended to look at me pitifully, and even shook his head in disgust. 
　　"Hurry up! Your mother will find out later!" I said angrily. 
　　"No...no..." Li Xiaojun continued to shake his head. 
　　"Ah..." Looking at Li Xiaojun's arrogant look, but still not letting me fuck her, tears were about to fall out of her eyes. 
　　I didn't feel pity for this, so I reached out and reached into Li Xiaojun's light blue college pants. Li Xiaojun curled up and wanted to escape, but he still let me go in. 
　　Li Xiaojun bit her red lower lip with her pure white upper front teeth. After exclaiming with some fear and excitement, she looked at me with tearful eyes. 
　　However, when I put my hand into Li Xiaojun's college pants, I touched a hard object that was cold and slightly hot. It was an object, but it felt like a piece of iron to me. 
　　I looked at Li Xiaojun in shock. 
　　"What is this?" I looked at Li Xiaojun in disbelief.
　　"Um...hum..." Li Xiaojun did not explain to me, but shook his head one after another, tears were about to flow out, and he held my hand with both hands and kept trying to pull me out. 
　　"Ah...Don't...Uh huh..." I seemed to think of something and pulled open Li Xiaojun's pants. Then, I saw a piece of stainless steel that I had never seen before, reflecting the light. Wear it under Li Xiaojun. 
　　Li Xiaojun blushed even more with embarrassment, tears fell directly from her beautiful eyes, and looked at me while sobbing softly. 
　　"Is this... what the hell is... stainless steel underwear?..." I stared at the device in Li Xiaojun's college pants in shock. 
　　"Uuuuuuuuuuuuuuuuuu" Li Xiaojun shook his head repeatedly, tears dripping down freely. 
　　"Don't cry, can you tell me what's going on?" I opened my eyes in shock, unable to calm down my emotions. 
　　"..." Li Xiaojun said nothing, forcefully pulled my hand away, then stood up and put on his pants. 
　　As she stood up, a stainless steel object similar to underwear was tightly locked on Li Xiaojun's crotch. Only two snow-white thighs were exposed from the stainless steel trousers. Just above the stainless steel underwear on the crotch, I also saw a Keyhole, like a keyhole. 
　　"Let's go..." After Li Xiaojun put on his pants, he wiped his tears, sat back in his seat, picked up his pen and didn't look at me. 
　　As I was staring closely at her lower body, I noticed that Li Xiaojun seemed a little mechanical when she sat down on her buttocks. 
　　"Did you wear it yourself? Or, who dressed it for you?" At this point, I seemed to understand that it must have been Sam's fault. 
　　"..." Li Xiaojun didn't reply to me and started writing review materials. 
　　"Is it...Sam!" I trembled, and when I said this sentence, I even felt myself vibrating. 
　　"..." Li Xiaojun trembled unconsciously, then returned to normal immediately. 
　　"Why?" I gritted my teeth and looked at Li Xiaojun's performance. Although she didn't explain, I knew that I guessed it right.
