It took me ten minutes to finish undressing him, ten minutes which only made me madder with lust. Tearing off the last few vestiges of his clothing, I...grabbed a pot from the bedside table and smeared Vaseline over my rock-hard cock, massaging my balls as I stood over him, desperate to consummate my love one last time. I got on top of him, like I had before, and, hooking my hands under his cold thighs, lifted his legs so that I could press the head of my cock to his opening. I pushed myself into. The house was situated on several acres of property and very secluded. It had a tall stone wall with cast iron fence along the top to keep out unwanted visitors, and I presume also served to keep anyone from leaving, not that I had any interest in leaving, in fact I was more than happy to think I would be here for the rest of my life catering to my new beautiful young mistress.We walked around back towards the pool and went into the pool house which also had a gym and full fitness center, bar,. I cried out for him to take it out but all he did was stop. He waited a few seconds to let me adjust and pushed further again it hurt but not as bad and he repeated this several times till he was all in. My ass was on fire and it felt like I was being torn in two, the pain was still intense but the full filling was almost euphoric. He rubbed my ass while he let me adjust and then started to slowly withdraw part way then pushed forward.He continued this five or six times until he was finally. It was not going to take much to push me over the edge. He then pulled back till his cock was almost all the way out and then pushed back inside me slowly. My son started to pick up some speed and I could feel his cock swelling. I wanted his cum inside me so badly, my cunt was gripping his cock tightly. "Cum inside me, please" I said. Then my son pushed deep inside me and stayed, I could feel his swollen cock, my pussy gripped it so tight. Then he moaned loudly as the first squirt of hot cum.
