I started to thrust gently, trying to use all the length of my cock to fuck my mom, then mom stirred, moaning and sobbing gently.Shit I thought, she�...s going to wake up and see her son fucking her but she just whimpered before passing out again. I kept the slow thrusting going, wanting to gain as much experience as I could.Trying to distract my mind from coming, I bent down and sucked on her tit, it was soft, wobbly, and lovely to suck but this heightened my desire to thrust a little faster.. She began giving a little more action."Watch out for your teeth," I cautioned as she began to scrape rather than tease. I'd let her do it her own way for a while before trying to instruct her. Not that I was such an expert. My only expertise was as a recipient, and even that was awfully limited. In my highly aroused state, she didn't have to be a trained expert to quickly bring me to a pre-orgasmic peak anyway, and I wanted to make this last. So I periodically took my cock out of her mouth,. Tracing my tongue out and around I tasted her juices and wondered which one this was. Licking gently up and down, I cautiously moved my head back and forth slightly, and then centered in on her clit. I was rewarded with a sigh of pleasure, then she thrust her hips forward slamming my head back onto the bed. Grinding her hips against me she forcefully fucked my mouth, gaining momentum and speed as she rolled back and forth on my mouth. It was all I could do, under her weight to keep from biting.
