My birthday finally arrived...it was a Saturday so there was no work for me to day...my mum and dad were coming over for breakfast so I knew I would have to move but I would have to soften my hard on first...just as I started to stroke my cock the adjoing door opened and gran came through to my room holding a card in one hand and what looked like my present in the other...she was wearing her nightie and I could see her heavy tit's freely swaying under the material....my cock was about to burst at the sight I was feasting on....gran greeted me with " HAPPY BIRTHDAY " and came over to the bed and leant over me and gave me a big kiss on my cheek....just for a breif second I was treat to a look down her nightie and almost got a full veiw of her tit's...oh this was torture...and then gran really shocked me....she lifted the bedcover and got in beside me...I wasn't wearing anything and panicked in case she saw my hard on...I don't think she did...at least she never gave the impression that she did...she gave me my card and present with a huge big happy smile....I had never seen gran as happy as this in ages....at least before grandad died...I opened the card first..."happy 18th to my dearest Charles form your dear old gran xxxxx "...it was the kisses I was most interested in...if only...then the present...it was only a small package...I guessed at a watch and was right....but what a watch....a VERY expensive one which I still have to this day and remains my prized possesion above any others.." oh gran...thank you....you really should not have spent so much on me....I put my arm around her neck to give her a big kiss on her cheek but just as I did she turned her head and I ended up kissing her full frontal....right on her lips...it only lasted about a second but it was the nicest thing that I had ever experienced in my life....my cock was now about to burst...it was almost painfull...gran smiled...not her usual smile...but a sort of smouldering almost sexy one...she then said that my mum and dad would be hear soon and she would have to get breakfast started...she got out of bed and went back to her room.....three or four strokes later I errupted....I manged to catch most of it in my hands...it just kept coming...WOW.
