Fucking The Boss

My boss is a 45-year-old brunette. She's a bit plump, but has got a pretty face and massive tits.

She made it clear that she wanted to fuck me when I joined the company. I'm 23 and had only been working there for two weeks when she sucked my cock in her office. We now have sex a couple of times a week, usually in her office or in her car.

The sex is good, she even lets me take her up the arse, but that's the problem. She's told me that she's bought a strap-on dildo and that she's going to take me up the shitter.
I'm really not up for it! But I'm scared she will make life difficult for me at work. So I’m going to lick her arse hole instead. She said I could do this as an alternative.

I’ve also been shagging my brothers wife's sister for the last six months. I was in the pub one night and saw the my brothers wife's sister. I told her about my problem at work and she said I could shag her to take my mind off it.

I thought she was joking at first because she only got married a year ago, but she wasn't.
She's brilliant in bed. She loves sucking me off and likes to be tied up and taken from behind.

She likes giving me tit wanks with those gorgeous big breasts of hers. Once I have cum all over her tits she licks it off.

I’m not sure she is a good a fuck as my boss though.
