My girlfriend, Steff, had just been out for a run. She came in all hot and sweaty and was going up for a shower. I followed up with a bottle of water. Steff was still in her sports bra and panties with a glistening sheen of perspiration on her shoulders. This turned me on and I had a rise in my trousers. I told her to stop where she was in front of the mirror. I kissed her shoulder and could taste the saltiness of her exercise. I then started to kiss down her back stopping just at the top of her pant line. She signalled me to stop, took off her bra and lay back on the bed with her arms raised. I climbed onto the bed and kissed and licked her all over teasing her nipples and savouring her aroma. I took her panties off and the glistening of her sex almost had me coming there and then. I moved down and eased her lips apart with my fingers. Steff shivered with anticipation, she was a whore for oral sex and I gently started licking and kissing her dripping vagina. After a couple of minutes she was writhing and pulling my hair desperate to keep my tongue inside her. She came in a hurry and released her grip. Straight away she got up for her shower, said 'Thanks'. As she walked to the shower, she picked up her sports knickers and tossed them over, 'These might help' and closed the bathroom door. I got undressed and breathed in the musky smell. Within 30 seconds I had come all over myself.
