Jerking off in the garden

I was all alone in the garden removed my clothes and wondered about naked playing with my cock. as it grew hard stroking it pulling on it getting very hard so started to wank off. then all of a sudden my wife's friend turned up walked though the house into the garden she saw me standing there naked jerking my cock .she froze for a moment before turning away . as she turned I said you don't have to go you can watch me if you like she turned back and sed only watch . walking towards me she put out her hand and grasped my cock tightly before stroking back and forth it felt so wrong but so good she got down on her knees wrapped her fingers round my balls as her mouth closed on my throbbing cock sliding all the way down and back up licking my knob then going down again she held it deep in her throat wile squeezing my swollen balls . I asked if she would take of her top she did willingly slipping of her bra seeing her big tits swing made my cock jerk I put my hands down to feel her soft firm tits stroking her nipples pinching them as she continued to suck me I could feel my cum begin to serge as I gasped she squeezed my cock in her hand and jerked me hard I could not hold it any longer as I spirited my hot cum over her face and tits she wiped herself of and said we will have to do it again some time I hope so I said as she left the looks she gives me now are full of lust
