This just happened this morning.
It's summer break, so I woke up this morning around noon. I came out of my bedroom and saw no one was home. There was a note on the table saying everyone went to my aunt's house to go swimming for the day so I'd be home alone. I hopped in the shower and started stroking my morning wood, when I had the greatest idea. My one friend, who lives down the street, was at summer camp. Her mom was at work. This meant no one was at her house, and luckily since our families are such good friends, I have a key to their house. I quickly took my shower and jumped out. I ran in my kitchen and grabbed the key. Then I walked down to her house, looked around to make sure no one was around, and slipped inside.
I locked the door behind me and stopped to listen for any noises (just to be sure). Hearing none, I took off my shoes and started up to her room. I climbed the stairs and walked down the hall into her bedroom. Jane's (not her real name) door was closed, so I opened it. I had been fantasizing about doing this for so long I stopped and took a moment to take it all in. A pair of her dirty panties were laying on the floor. I picked them up and sniffed them. Her pussy smelled so sweet. I took off my clothes and put them in a pile on her floor. I sat on her bed, sniffing her panties and jacking off. I blew my load pretty fast in them, and then I threw them back on the floor. My heart was pounding as I lay on my stomach and humped her pillows. I blew another load in those too. I decided to check out her moms room, since she was definately a MILF. I walked into Michelle's room and saw she hung her bras on a rack on the wall. I grabbed one and smelled it. I jacked off and blew my load in one of the cups. They were a decent size (size C) and I nearly filled it.
The next thing I knew, Michelle was standing in the doorway! I was sitting on her bed, naked, wearing one of her daughters panties, with my hand around my dick, holding one of her bras covered in my cum. I almost passed out. I had no idea what to do. We just looked at each other for a second. I started stammering 'I'm sorry' a bunch of times, and she just kept standing there. After a minute or two, she walked over and grabbed her bra back. I thought I was in so much trouble. but, to my surprise, she started LICKING my cum off her bra. I was really confused. She looked at me and said 'It's ok, don't worry about anything. I understand how hard it must be to be young and horny. I just came home for lunch and then I was going to masterbate myself actually. What a coincidence, maybe we could do it together?' I swear that's exactly what she said. 'okay!' I started smiling.
She took off her blouse, skirt, bra and panties. She spread her pussy lips and guided my hand to it. I started fingering her, and she started moaning. She grabbed my hand and said 'I just want to warn you, I'm a squirter. Do you know what that means?' of course I did! hearing this, I started fingering her twice as fast. The next thing I knew, it looked like she was pissing all over the room. It was like a waterfall. She squirted for at least fifteen seconds. 'Wow, thanks, that was just what I needed' she smiled. 'I never get any help anymore since I got divorced. Now can I do you?' I was more than willing! She started jacking me off and in no time I was cumming. I shot across the room, and on her breasts. She was laughing the whole time, and when it was over she threw me the panties she had just worn and told me to keep them. I grabbed my clothes and threw them on. It was the greatest experience of my life, and I got two pairs of panties and the two bras I stole out of it. This means many more fun times! I'm so glad she came home for lunch.
