I have three:

1) I had a lazy morning with my first serious GF. We were students at the time and we just didn't bother going in that day, enjoying some early morning shagging whilst my house mates were gone. Around lunch we decided we'd better get up. My GF was laying on the couch watching TV and I asked her if she wanted anything. She asked for a cup of tea and I brought it in to her. After I placed it on the coffee table I leaned over and kissed her on the lips.

As I went to go back to the kitchen, she grabbed my trouser leg and said "Don't be in such a rush!" She then opened my trousers, took out my dick and started to blow me! Nice. It was probably the first time I'd been sucked whilst standing up and, after a few minutes, my legs started to thrust towards her, still lying on the couch. "I'm sorry" I said,"I can't help it."

"It's ok", she said, "let's try it." And with that I started to face fuck a girl for the first time!

All was going beautifully, until we suddenly heard a key in the front door. I hurriedly pulled away from her and tucked everything away as best I could, just in time, before one of my house mates came in the door. He acknowledged us but carried on into the kitchen.

The thing is, the front door was just outside the window, at right-angles to it. Often, when friends would call round, they'd ring the bell and then wave in the window to us. He must never have even glanced in the window though, as he fumbled with his keys, as I'm sure he would have taken the piss out of me for the rest of the year.

2) Different girl and different house mate. A few years later and I'm up in bed with my new girlfriend, again during the day when we should be at class. This one was a virgin when we started going out (and pretty conservative at that) but I managed to open her mind to a few things. This particular afternoon, she's riding me reverse cowgirl when we hear my house mate return home. We're having far too good a time to stop but we both quietened down, obviously.

I played a lot of tennis with this housemate. It turned out (we found out later) that he'd been chatting up a girl in the cafeteria and had found out she'd like to play a game. She had no racket though. No problem, he'd pop home and borrow his house mate's!

Not knowing his plans, we didn't think there was any trouble when we heard him climb the stairs. We were still in stealth shag mode. Next thing, the door to my room bursts open.

My lady lets out a scream and the guy freezes. Lucky for her, the bed was to the left of the door and the door swung in to the left so it basically blocked the view. He realized what was going on and he quickly said "Sorry!" and pulled the door out.

What he didn't realise was what he almost saw! Afterwards he told me he presumed he'd almost walked in to see the covers of the bed moving up and down. "Hard luck man" I told him, "you'd have seen [my gf] reverse cowgirling - and looking straight at you." I think he then regretted that he hadn't 'accidentally' kept walking for another step before freezing!

3) Final one, current lady. She has a (non-identical) twin. The first summer we were a couple, she went home from university to her parents' house. I visited for a few days. One particularly fine day she was wearing this lovely one-piece tennis dress. I mentioned how hot I thought it looked and she, as pretence to get us some privacy, asked me to come down to her room to help lift down a box from the wardrobe.

Her room had two single beds and, as the sister was also home from college, they'd basically reverted to sharing with each other again. We started to make out before she stood back from me and shimmied out of her underwear. She then pushed me back onto her bed, opened my trousers and took out my dick. I was well hard enough so she straddled me and we started shagging.

It was so hot and she got particularly into it, cumming three times before I heard some footsteps on the wooden floor in the hall way. Hoping it was someone going to a different room, I didn't stop her. Next thing, the door opened and in walked her sister.

I grabbed her ass as tight as I could to stop her. However, the fact that we'd been having some great sex and the hotness of the situation meant that, right there at that second, I came! My gf remarked afterwards that it was so strange to have the two of us frozen whilst she could feel my dick spurting inside her. :-)

As it happened, she was lying completely flat on me - so the sister must have presumed that she had interrupted us kissing. She said "Sorry, won't be a sec" and got whatever it was she wanted. She certainly didn't rush out of there!
