My mistake was masturbating twice after she went up to bed. As soon as I went to bed, she was chatting. She then said, "you've got 20 minutes". I was gutted as I knew I wouldn't be able to cum, but thought I'd do it any way.

She was naked in bed with the tiniest knickers on. So I went straight for her breasts. As I did, she grabbed my cock and started masturbating me. She then lay on her back and I straddled her. As I  carried on sucking and licking her nipples and getting a handful of boobs, she used my penis to rub her clit. I helped with some thrusting. She was rubbing me on herself quite hard and fairly quickly came. She lay there writhing around for a bit and then got onto her back again and opened her legs. I got between them and inserted my cock in her wet pussy. I thrust while up on my arms so we could see our bodies and watch my cock as it slid in and out. After a while, I pretended to cum with a couple of big thrusts and pulled out.

I was glad I had pleasured her. It was fun.
