He continued to suck faster and I felt his tongue now teasing the piss slit of my knob. I could feel my prostate fully loaded with sperm ready to come... I would not be able to control my ejaculation if he continued in desperation and I released waistband of my underwear that I was holding down with my right hand slap.I took my right hand and tried to push the front of his head away. I can’t control it anymore stop and I’m going to cum I said. His left hand grabbed my ass for a second I thought. “Wow!, haven’t you grown” she said admiring my throbbing erection and she reached up taking it softly in her hand and as she pulled the skin back to expose the head a little stream of precum flowed out the tip.“Mum?” I said half in protest but was happy to have her holding me, I had that feeling in the pit of my stomach and when she ran her finger across the swollen head massaging the precum in I thought I was going to shoot my load there and then.She leant forward and slowly started to lick. He couldn't find that special spot inside by himself!" Mom squealed."Well ma'am, I'm extremely busy as you can see, so my suggestion is that you take your boy to our secondary bathroom downstairs in the basement to get the sample. I wouldn't want all these patients to see you and your grown boy go into the bathroom together and come out with a cup of his semen." The nurse replied and walked off to go about her business.That's when my mother walked over to me with a cup in one hand and she. I informed her of my situation, to which she sped up her motion and swallowed ever drop or my seed. We exited my truck immediately following and scurried up the stairs to my apartment. As I locked the door behind us I swung her around to face me, desire was in her eyes as we kissed while I lead her to my bedroom. Once I lay her on the bed I began slowly kissing down her neck, reaching the top of her blouse, I unbuttoned it slowly kissing every inch of skin as I removed the clothing covering.
