My step-son has been acting very strange around me lately. Every time he enters the room and I try to engage with him, his eyes wander off, and it’s like he’s in a daydream or something. The other day he must of gazed off 10 times in front of me, and he kept getting an erection each time. Well I was about to get into the shower, when he came walking into the bathroom, and he immediately got hard. I asked him if all his daydreaming is about sex and he said “yes”. I then asked him, “is it about having sex with step-mommy?” and again he said “yes”. I asked him if he was curious about what it would be like to fuck his own step-mother and he said it’s all he ever thinks about. I don’t know why but his answer got me immediately turned on. I couldn’t help but notice how hard his perfect erect cock was and it was making me get soaking wet. I was so turned on that my pussy started pulsating inside of me. It was physically yearning for my step-son’s penetration. This must be how he felt every time he’d get lost in a daydream. I let my urges get the best of me and I told my step-son to take me into his bedroom if he really wanted to fuck me! Within minutes we were both completely naked and climbing into his bed. He laid flat on his back while I straddled myself on top of his waist. My step-son was trembling from excitement and nerves, so I told him to just relax and let step-mommy do all the work. I then slid my now soaking wet, tight, warm pussy on top of his huge, erect cock and I slowly slid him inside of the pussy that birthed him. I could have orgasmed right then and there and I could tell he was already about to cum too. I told him it’s ok honey, cum inside of your step-mommy. Fill me up with your huge warm load. step-Mommy wants every drop of your cum to go inside of her. I started to ride him fast and I made sure he was deep inside of me. I could feel he was about to explode and with one more thrust of my hips, we both came harder than I think any 2 people have ever cum. I kept moving my tight, fat pussy over his shrinking cock and within seconds I could feel it growing inside of me again. In minutes he was hard as a rock and we fucked so intense and so passionate, I don’t know how I’ll ever be able to resist his cock again. This is how my step-sons taboo daydreams about his own step-mother turned into the best reality we’ve ever known!
