A few months ago, I broke up with my girlfriend of five years and moved out of the apartment that we shared together. Ever since then, I haven't been able to stop thinking about her. She's moved on with her life, but we've tried to stay friends. Recently, she started seeing another guy and that's all she's been able to talk about since. She just goes on and on about how hot he is. A couple weeks ago, she was telling me that even though they hadn't had sex yet, she was feeling his crotch with her hand as they were making out and she could feel that he had a really big dick, which excited her. I was a little embarrassed that as she was telling me this, I actually developed a huge hard on just seeing the lustfulness in her eyes. To tell you the truth, I couldn't remember the last time I was so turned on. She proceeded to tell me how excited she was because the following Saturday he was taking her to a movie and after they got back to her place she was finally going to give it up to him. Once again, just seeing the drooling lust in her eyes as she told me this turned me on so much I could barely contain myself. That night I just couldn't stop thinking about it and found myself jerking off endlessly to the thought of my ex getting fucked by another man. Then, finally, a very naughty idea came to mind.
That coming Saturday, I parked around the corner from the old apartment that we used to share together and waited for her new man to show up. When he finally did, I saw she wasn't lying about how good looking he was. I was actually a little jealous, but at the same time I was surprised to find myself sporting a major hard on as soon as I saw that same lustful look in her eye as she came out to greet him. As soon as they drove off, I walked up to the building and pulled out my spare key, which I hadn't told her about before moving out. I let myself in and relocked the door behind me. As I waited for them to return, I slaked my appetite by rooting through her panty drawer and checking out her vibrator and other naughty toys. I found a particularly luscious pare of satin panties lying in the hamper and stuck them in my pocket.
As soon as I saw his car pull up, I hid in the coat closet and waited. I watched through a crack in the closet door as they entered, joking and laughing. He sat down on the couch as she went to the kitchen to get a couple beers. As soon as she got back, it didn't take much chit chat before they were making out like banshees. I watched eagerly as he slipped his hand up her shirt and she proceeded to pull it off along with her bra so he could suck on her tits. Man, I missed those tits. I could barely contain my raging hard on as I watched them through the closet door. She moaned, "Oh god, I've wanted this so much," as he sucked on her tits.
"Me, too," he said breathlessly as she worked herself against his lap. Then she climbed down off the couch onto her knees, unzipped his pants and pulled out his throbbing hard cock, which was every bit as huge as she said it was. She held onto it with one hand and started sucking on it as he moaned. I had never seen anything so hot in my entire life.
Just then, she hoisted him up and led him into the bedroom, out of sight. I waited a while before slowly sneaking out of the closet and peered around the corner. The bedroom door was open just a crack and I could hear her moaning. I snuck up to the door, got down on my knees and peered through the crack. They were both buck naked and he was plowing her doggie style with his huge cock ramming in and out of her as her tits bounced back and forth and her mouth just hung wide open, screaming in ecstacy.
I couldn't contain my hard on any longer. I unzipped my pants, pulled it out and started beating it furiously, trying not to cry out with pleasure myself as I watched him give it to her. I pulled the pair of her panties out of my pocket and got ready to catch my cum with them.
When he was finally ready to cum, he pulled his dick out of her just in time as splooge began exploding from the end of it like a fountain. She sat up and put his dick in her mouth, sucking the cum off of it as he grasped her tightly and moaned. It was at that moment that my own dick exploded into the pair of her panties that I'd commandeered as I bit my lip to keep from crying out.
I watched him give it to her once more as I masturbated furiously before finally sneaking out. That was only a couple weeks ago, but I already know it was an experience I'll never forget. I still think about it every night as I jerk off.
