He resists

'I tried to resist, all the next day. She kept reminding me - as soon as her mum got back she would be telling her all about me. Again, she spent the whole day following me about, this time she didn't put a stitch of clothing on all day. She just sat in the office all day, either reading a book, on her phone, or masturbating. If I wasn't on a call she'd come over and massage my shoulders, or put her hand in my crotch. I was hardly getting any work done. If I left the room she'd follow me, if I went into my bathroom she'd be there when I got out, lying on my bed, legs spreadeagled or ass in the air, periodically she'd put in a butt plug. And over and over again, just fuck me Bill, just fuck me, I know you want to, then you're safe.'

'And what happened when Bev got home?'

'She was on the phone when she got in, and indicated she was going to take a shower, which she often did when she got in from work. Summer sat at the kitchen table and said she was going to tell her mum everything when she got out the bathroom. She had put on a little denim skirt, and halter top. It was suddenly apparent that I could be homeless pretty soon.'

'What did you do?'

'I fucked her. I had ****. I walked over to her and said ok, bitch you win. She got on her knees, pulled my jogging pants down and started sucking me - she was no amateur, let me tell you. We were short on time, I didn't want to get caught, so I sat on a chair at the table and she turned away from me and just impaled herself on my cock, no half measure. She just sat down on it, right up to the hilt, and started bouncing up and down. She was definitely pretty experienced, but still tight, I knew I wasn't going to last long. A couple of minutes later and she was squeezing my cock for all it was worth and I came inside her. We could both hear that the shower had stopped, so we didn't have long. She dismounted, then licked my cock clean, and a minute or two before her mum came back into the room she sat at the table as if nothing untoward had happened. When Bev came in and started to get things ready for dinner, if her back was turned, Summer would open her legs, stick a finger in her pussy, and then lick my cum of it provocatively, grinning at me. That's when I realised that she wasn't going to be satisfied with one fuck. I had a feeling things were going to get worse for me.
