Sarah and I had been together for about a year when she agreed to move in at weekends. It made sense. I lived on the outskirts of London and she worked in the city, so spent the week at her flat before commuting out of the ‘smoke’ at weekends.

Her friend Ellen was coming up from the south coast to stay and check out the changes Sarah had made to my (ex) bachelor pad. They had worked together during training as nurses but after qualifying they had moved on to different medical fields. Ellen, like Sarah, was a particularly wild and sexy girl and often recalled stories about the wild past when they were student nurses

This visit was similar to those before. Off to the pub for a few drinks, where as normal, the conversation eventually came around to adventures of sexual nature at the teaching Hospital. Ellen revealed a new story of when, following inhalation of various medical gases, she fucked a Dentist by sitting on him whilst he was laid out on his Dentist chair. The foreplay had been interrupted by a phone call from his wife during which Ellen had sucked him off but wouldn’t let him cum.

When we got back to my place, I was gagging for sex, but Sarah and Ellen had lots of ‘catching up’ to do. The conversation went on for sometime. I tried to look interested but I was bored shitless and could only think of one thing. I went to the kitchen to sort out coffees, and as a joke, I strapped a redundant padlock and cord over my favourite breakfast cereal as I remembered that Ellen had pigged almost the whole box during her last visit.

I took the coffee in for the girls but couldn’t find an appropriate time to reveal my ‘joke’. Later Sarah disappeared to the toilet, so I revealed the ‘locked’ box of cereal to Ellen. She said I was “a mean asshole” and tried to get the box from me. The struggle become almost a wrestling match, but she decided to use an unconventional testicle hold to force me to hand over the cereal. Frankly is was far more sexy than painful to have her holding my balls through my jeans. I decided to return the compliment and stuck my hand up her skirt. She was wet, very wet. I traced the outline of her pussy through her panties and was about to touch flesh when Sarah came downstairs. By now we had returned to a normal wrestle and Sarah found the whole joke very amusing.

That night, I fucked Sarah like a man possessed. She sucked me off first. I don’t think I have ever cum so much and she was definitely surprised. In the morning, Ellen was up early. “”There go my cereals!” I thought. Then a knock at the door, and there she was, dressed in a short-ish tee shirt her panties clearly visible below the hem. She’d bought us tea and toast for us to “help us recover”. She had obviously heard our session last night.

As we enjoyed our surprise breakfast, she sat on the end of the bed. Sarah sitting parallel to my right, and Ellen facing me to my left with her feet under the duvet and by my hip. We chatted for a while and my hard-on was just subsiding when Ellen’s hand found and rubbed my foot/lower leg under the covers. She said she was surprised how hairy my legs were. Sarah said she loved them, and especially loved the feel of them on her inner thighs when we were fucking. Sarah then said her favourite bit was at the top of my inner thigh where there was a bald section (where the legs rub together).
At this, Ellen’s hand travelled at some speed up to my left inner thigh to investigate. I thought I would cum at any time as she stroked the bald section of skin remarking how smooth it was. I glanced at Sarah not knowing what her reaction would be, but she was just smiling at me. She revealed later that she found my mouth-open-surprised expression very amusing.

Ellen then accidentally (!) brushed my balls and prick with the back of her hand and feigned surprise that “we have got him all excited”. Sarah pulled back the duvet, revealing my hard-on and said it would be a waste to leave it. Ellen agreed and bent forward taking my dripping prick straight into her mouth. I again looked at Sarah for permission. She answered by bending forward to lick my nipples.

I complained that my nipple were a little sensitive. It wasn’t true, I wanted to watch Ellen who was busy sucking me hard. The idea that my prick had been up Sarah prior to being in Ellen’s mouth made the whole situation amazingly sexy. Sarah then moved to cup my balls and scratch my thighs as Ellen continued her expert blow job.

I’d like to boast that I lasted for ages. I didn’t. After about 8-10 minutes, I could hold back no longer and warned Ellen that I was cumming. She proceeded to suck even harder and faster, eventually swallowing every drop (something Sarah wasn’t so keen on). The after a few seconds of almost embarrassing quiet, frankly not knowing what to do, and who to do it to, Ellen kissed me on the lips, then did the same to Sarah, said thanks, and disappeared to the bathroom for a shower.

I turned to Sarah and said something pathetic like “fucking hell, I don’t believe we just did that”. She replied that she needed fucking right now.

I never did fuck Ellen that weekend (try as hard as a might), but I did eventually catch up with her to repay my dues during a business trip to the south coast. Shortly after she got a serious boyfriend who she married, as I did to Sarah in the same year.

Like most men, I have dreamed of a FFM threesome, and am not sure whether my experience was truly a 3sum as I didn’t fuck both of them at that time.
