We had the odd mess around in the garden - I would come up behind her, kiss her neck and my hands would be on her tits, tweaking her nipples. On one occasion it seemed right to lift her top and get a good feel - she liked that and reached around, hand up my shorts feeling my cock.

I noticed that our neighbour was in the garden, looking our way but Sue wasn't wearing her specs, so had no idea. 

Her top was soon off and my fingers were turning her on as she turned around to unzip me and pull out my cock.

Our neighbour was still looking as Sue started to wank me off with me still playing with her tits and removing her shorts so that my fingers could slip inside her knickers.

We were soon naked and Sue offered no resistance when I pulled her knickers down, bent her forward and my cock was soon at her slit, being guided in her hand for a fuck, still with our neighbour for an audience. 

After we had finished, I whispered in her ear about being viewed and all she did was turn and face his way to give him a good view of her naked body.

Its a hot day today as well!
