“That’s it, honey; just like that. Such a good boy, you know just what Mum wants, don’t you?” Every single time I’d tried dirty talk before, I felt like such an idiot. But my son clearly fucking loved it, and like I’m sure I’ve said a dozen times by now, I loved knowing I could turn him on as much as I did. “I want you to cum inside me again, Joel; fill your mother up with your cum, my darling son.”
He kissed my neck and sucked at my earlobe while keeping the incredibly fast pace I’d set for him. “Keep talking, Mum, I’m getting close.”
“Ooh, good boy! Fuck Mum hard with your big, thick cock,” I moaned into his ear. “I want your cum deep inside me, baby boy, you beautiful motherfucker. Shoot it right up there, Joel. Such a good son. Mummy loves you so much.”
That just about did it. Seconds later, he was yelling out “I’m gonna fucking explode, Mum!”
“Good boy,” I cooed. “Cum for your mother, my darling baby boy.” And he certainly didn’t disappoint. He arched his back, shoving his dick as far inside me as he could. His stomach spasmed as he yelled into the wilderness. My muscles clenching tight around his cock, I felt ever spurt of cum rising from the base of my son’s manhood, then bursting out and into my insides. His orgasm lasted more than 30 seconds, and he must’ve shot at least eight or nine distinct loads of cum into my vagina. Not quite as much as our first night together, but noticeably more than the amount he’d shot onto my breasts last night. “That’s my boy,” I whispered as I kissed his neck.
As tempting as it was to just lie naked in the grass and see how quickly it’d take to get a sunburn, Joel was still technically working, and we still had a fair amount of ground to cover before we reached our last stop before Melbourne. Sure, less than five minutes had passed since we pulled over, but we were still on a deadline. He gave me a quick but passionate kiss on the lips and gathered up his clothes. I followed him, brushing the dirt and grass from my back and my butt cheeks. I knew before I even saw my shadow that my hair was a mess, but hey – that showed just how quick and dirty our little pitstop was. We both got dressed and returned to the idling truck.
He offered me some tissues for the cum that would inevitably leak out, but I declined. This will probably sound really kinky or even perverse, but I really enjoy the feeling of cum leaking out of me. It’s probably why I’d never had (or let) anyone cum on my breasts or face before Joel. So I let it all ooze out during the course of our drive. It really turned me on feeling all my son’s semen leaking out and staining my underwear and then my skirt. I don’t think he minded seeing it either, actually. Having had my fill for a little while, I decided to be kind to Joel and so I did up three of the buttons on my shirt this time. We chatted and rested our hands on each other’s legs as he drove.
I dozed off occasionally, and one time when I woke up, my son informed me that I looked “so damn cute” when I slept. “Not as cute as you did when you napped as a boy, my darling son,” I teased. He went very red at that, and I chose to make it worse by telling him, “And you’re looking very cute right now, blushing away.”
