I fuck her slowly to enjoy the pleasure of being inside my mother. But as I pull in and out of my mom she commands me to fuck me harder, so I increase...speed on my thrust and each time my balls would hit her ass.“Ahhh… ahhh… why can’t you fuck me like this last night?” said mom while moaning.As mom continues screaming for pleasure, I started pumping her faster and faster. I can now feel my dick is about to blow.“I am about to cum, don’t cum yet Jim” said my mom.“I can’t hold it mom, ahhh…” I. Mary felt all of it deep inside her where no other person had eve been. She lifted her hips and fucked him. She held on to him and worked her pussy around and around on his shaft trying to please him like he had pleased her for over 40 minutes by fucking her.He roared again, "Oh........... fuck!!!! I'm going....to...cum! Going..to..cum! Oh......God...Oh....fuck.....here.......it......comes......baby!He strained one last time but it was just to hard. Then he let out a cry like a lion and erupted. As you may recall, an older sister, Janine, had chanced to come into Kelly's room while she was rubbing my penis. That led to Janine getting involved in our escapades. It became a threesome after that.After Kelly left for college, Janine and I continued our liaisons in her room until my parents moved in one of the little sisters, Sandra, to share her room. That caused us to resort to the barn or a field to continue our sex games. As I explained before, this was nothing but taking advantage of. She looked so beautiful that I got a little lump in my throat. Her long, ash blonde hair was brushed to a shiny glimmer, hanging down below her shoulders, and her diamond blue eyes beneath her dark, full eyebrows were sparkling with... with what? I don't know. But at that moment I should gladly have changed the red and white of our national flag to those colours: Yellow, ashen greyish and diamond blue."Welcome home, dear. Had a hard day?" No, not really. Busy, fortunately, but not strenuous..
