I was the one from post #13674 that wanted to nail his step-mom. I'm happy to say that it happened! We were alone in the house and she told me she overheard the fight my ex and I had when I called out my step-mom's name as I came in her. She told me she was flattered and then asked me if I could keep a secret. I said yes and she told me she has fantasized about me while getting herself off a time or two. I said too bad we couldn't actually act on it. She just smirked and walked away, strutting her ass as she left the room. A couple of hours later, I'm in my room and she walks in and tells me she has an idea. I say okay. She sits on my bed and tells me if it's too crazy to let her know and we'll never speak of it again. I saw okay, again. She tells me she's been thinking all day about me doing my ex and calling her name as I finish and it really has her turned on the more she thinks of it and she thinks she has a way to alleviate this interest we have in each other without actually doing anything we don't already do. Again, I say okay. She tells me we should masturbate in front of each other. I jumped from my chair and went, "Okay!" She smiles, walks to my door, closes it, and then stands awkwardly before me. Then after a second she says okay and pulls off her shirt, revealing her huge, natural breasts in a black bra. I was already hard. She took off pants and showed her black bikini-style panties and I could see her pussy glisten, already wet. Then she sat on the bed, towards the front where my pillows are and removed the panties. Then she looked at me expectantly. I quickly stripped down and when she saw my already hard cock she smirked and kind of bit the tip of her finger. I'm not going to lie and brag about my cock. It's about 7" and average width. Nothing spectacular, but it does what I need it to do. I asked her if I should sit in the chair and do it and she thought a minute and then patted the bed in front of her and said "No. Sit in front of me so we can feel each other's heat, but just remember no touching." I quickly did so and we were pretty close to each other. Close enough that if I wanted to I could push my cock forward and touch her pussy. Her legs were spread and she was on her back and I was sitting between her legs. She started rubbing her clit and she moaned and said my name and I was already ready to pop right then, but I started stroking slowly. I didn't want to finish before she did and I wanted her to be aware of that. I told her she was so damn hot. She told me she needed to see me cum. Not wanted, NEEDED. She asked me if I liked thinking of her when I fucked all my girlfriends and I told her I wish it was her I was fucking so I didn't have to fantasize. After about 10 minutes of this, of her fingering and rubbing herself, of her grabbing her tits and moaning, I was so ready to explode. Then she moaned my name and told me I was going to make her cum. Then she arched her back and said she was going to cum and said my name again. This was too much for me to take and I jumped on top of her and slid my precum covered cock into her hot, very wet pussy. It was the greatest feeling I ever felt. I started ramming her hard and fast and I could feel her pussy contract in orgasm, which triggered my own. Her legs were wrapped around mine and her hands were holding my arms and she kept moaning "Oh God, oh God!" over and over. For a few minutes I was ramming her hard like this as my orgasm came over me like waves until I finally shot perhaps the biggest load of my life to date up inside her. I moaned her name as I came in her and she put a hand against the back of my neck and breathed heavy into my ear. After my balls finished draining in her I collapsed on her and we just laid there silently, breathing heavy, until my erection finally softened enough that I just sort of fell out of her. Then she pushed me off her, got off the bed, grabbed her clothes in a bundle, and then stormed out of my room, slamming the door as she left. She hasn't spoken to me since.
