Till the cock in my ass pulled out. I quickly pulled my head off my throat invader and turned around getting on my knees to look through and he shoved...his cock back through as I quickly engulfed it in my mouth. It didn’t take long before I could feel my head being forced down onto the cock by my shower buddy. Forcing me to take as much of the cock as possible till his cock started twitching and spurting out hot jets of cum into my mouth and throat. I couldn’t help but gag I was trying to pull. YoursDr. SunderP.S. please make the regular visits somewhat longer for prolonged tests.The last line was the one that caused me great concerns is mom having sexual relationships with random men whom I did not know? Was this doctor also one of her lovers?I could only find out all about this once mom starts to open up to me regarding her sex life, and then maybe I can have my own sexual adventures in front of my own mom, or maybe she can join in in my fantasies and have fun with me. I was. We reached our accommodation, while I settled all the students in a much bigger place. She came with me and she told she will take the ground floor and I agreed to it.I took a bath as it was a long travel. I came down, but there was no noise. I slightly peeked into her room with a knock to enter. But she just came out of the bath with a towel in her chest. I could see her white milky thighs and her moles in the thighs. She did not notice me I was watching her. But I didn’t want to make a bad. We were ready to accept him as he was and not search for trouble or targets to moralize him.That said, he was pretty quiet as he has always been. He preferred watching rather than getting too involved. But it was a bit different this time; he didn't just observe us while fantasizing about girl-on-girl action. He was doing it more to understand us, to understand me and what I was doing here. The types of questions he asked were quite different from what I heard from him before. It wasn't.
