The mother in law has had a thing for me for years and I knew it, she used to flirt with me. Any how it all started after her husband died, one afternoon while visiting her without the wife we got round to the subject of sex, she explained that she had not had it for about 35 years and had often masturbated thinking about me, this got me quite excited and began to push the subject further. We chatted about the subject of her not getting and being satisfied by her husband, about 2 hours went by and all this talk of sex had got me all excited so I whipped out my cock, I asked her if this bothered her, she said no and she would have me do her if I was not married to her daughter. So I started to wank off in front of her eventually spraying my cum all over her bed, she said she had enjoyed watching me wank off and maybe I could help her have an orgasm some time, I said the pleasure would be all mine. So time went by and the opportunity to be alone again arose, I then asked her had she been pleasuring herself since our last encounter, she replied yes but you really need a partner to do it for you! I asked if she would like me to do it for her, the answer came without hesitation, YES! with that we undressed and she lay on her bed, I started to fondle and massage her breast then move lower to her clitoris, she was already wet between the legs and me softly massaging her clit and inserting my fingers into her got her out of breath and moaning, I was kissing hers breasts and lips while keeping the motion going, as I started to move lower with my tongue, i finally reached her clit with my tongue and licked as if my life depended on it, I brought her to orgasm and lay by her side for a few minutes, giving her time to recover, when she had recovered enough she reached out and grabbed hold off my cock and wanked and sucked me off, I came spraying her face with seman. She explained she was grateful for my attention and we should do it more often. If only all mother in laws were like mine...
