Three months that had passed since that life-changing day when her son had fucked her. She was 34, he soon to be 18. They now screwed regularly and had together worked out how to separate their sex sessions from their day-to-day lives.

The basement of their home that housed the laundry equipment had been partitioned to provide a small recreation area with a bed in the centre and screened dressing area where his mum kept her collection of sexy lingerie recently purchased from an Internet sex site. Everything relating to their incestuous relationship was kept in that basement room, so that when they finished their sessions she could dress in day clothes, walk upstairs, shut the door, and return to ordinary life.

At the start he fucked her hard up the arse and in the months that followed she’d trained him in his need for rough sex ‘you can hurt me, but you mustn’t injure me’. She found that she enjoyed the mild pain he inflicted heightening her own satisfaction.

His 18th birthday was coming up and she’d decided to get him something special. A nicely gift-wrapped girl! She’d trawled the Internet escort sites looking for a suitable local candidate. ‘Tracy’, her website said she was 18 and gave a description of her vital statistics and went on under ‘likes and dislikes’ –

Out calls only. Enjoy giving and receiving mild dom. Giving and receiving spanking. C.I.M’ – she didn’t understand that, and ‘Watersports’ – What on earth was that? .‘Please do not ask for bareback. Sorry guys, I don’t do anal, too small!’

‘ Only 18’ she thought. ‘Still, if young girls were going to advertise their bodies for sale, they deserved what they got’

‘Thanks, mum ‘, he said when she told him about Thursday evening’s treat. The next two days passed slowly until the doorbell rang. She answered the door. The girl was reassured to see it opened by a more mature female dressed in denims and a simple top, fair hair pulled back to a into a girly ponytail. ‘You couldn’t be too careful could you?’ The girl turned and gave a nod to a figure sitting in a parked car on the other side of the road. ‘It’s Tracy isn’t it?’ she said. ‘He’s downstairs in the recreation room’ she said. ‘You’re his birthday present from me. Let me take your coat and deal with the finances’. She handed Tracy the cash they’d agreed for a 2-hour session. Tracy opened her little shoulder bag unzipped a pocket and pushed the cash inside. ‘Thanks’ said Tracy, turning her back to slip the coat from her shoulders.

She gave Tracy the once over. Shiny shoulder length auburn hair with expensive highlights. Glowing youthful complexion, wearing a hint of eye shadow, deep red lipstick. Lovely peach shaped buns in tight powder blue shorts with the lower part of her cheeks just showing at the bottom. No sign of a panty line. Breasts larger than her own slightly spilling over the top of a little cotton strapped vest. A hint of nipples visible through the material. ‘36C cup’ she thought and she could see between the gap of her tits that she wasn’t wearing a bra. Knee high boots with heels ‘Cheap and a bit slutty’ she thought ‘Still, at least she’s knows what she’s here for’..

As Tracy turned and she glanced down the front of her body as if checking the goods. ‘Good tits’. Her bare midriff showed a single gold stud in her navel. The little shorts were certainly short – almost a size too small. Skin tight, they sat on the top of her hips clinging to the mound at the top of her vulva accentuating the shape. Her own wetness hoped upon hope that she wouldn’t just be watching! Thinking of what might be, she reproved herself ’How easily these dirty words, arse and cunt roll round my mind nowadays!’

She led the way down the stairs to the basement. He had heard them coming dressed casually in sports shirt, shorts, and sneakers. The instant the door opened their eyes met. ‘Selina’ he said. His mum said’ I thought her name was Tracy’. ‘It is Selina – I use Tracy when I’m working’. This was the Selina, recent new arrival in town, the ‘good’ girl who he’d dated some weeks ago and when he’d put his hand on her knee she’d pushed it away saying ‘I’d like to get to know you better first’ He didn’t get to know her better – he’d had a better offer – from his mum!

‘I had to start escorting’ said Tracy ’I couldn’t find any other work and I need the money to pay for college.
