In the early 1990's after we had our first child we would go an annual holiday with the in-laws to various parts of Spain. I must say I got on very well with my in-laws and we always has great holidays. We had rented a private villa in the hills not far from Benidorm for a two week stay and very nice it was. It was on quite a steep hill with a long sloping garden with a pool at the very lowest level. it was such a chore to climb back to the villa in the heat that we always took drinks and snacks down to last most of the day. Everyone loved sunbathing but no-one more than my mother in law. She always wore bikinis of various designs and was quite a looker particularly with her huge boobs swinging about in flimsy strapped bikini tops. After a few days of the holiday she decided that wearing a top was too much and decided to topless sun bathe. Wow what a site, lovely big boobs with huge circular areolas and big round nipples. I was in heaven, the bulge in my speedos was difficult to hide. The topless theme continued even when we went up to the villa for drinks etc prior to getting changes to go out. One week gone and father in law had to fly back to the uk to run his business. One afternoon around the pool the boobs were getting to me and I had a real erection difficult to hide without lying on my front. After lunch I decided that a visit to the villa for a wank was needed to relieve this pent up frustration. So sitting on the edge of the lounger I announced I was going up and would be down in 30 minutes or so. i noticed the mother in law look over and view my obvious bulge. nothing was said. I'd been up in the room for a couple of minutes, all doors open when I spotted the mother in law standing in the doorway. She said "it's really hot out there this afternoon and I've come up to cool off". I watched as she eyed my speedos and then said is that because of these and jiggled her boobs. I had to admit and she came over and said "well let me sort it out for you". at that she stuck her hand down into my speedos and grabbed my stiff cock. She moved the speedos down my legs and fell to her knees taking my cock in her mouth. She sucked and licked for a few minutes and then got up dropped her bikini bottoms and said "lick my pussy and fuck me". Another surprise in that a lady in her early 60's had a totally shaved pussy! At this point I was shaking like a leaf, partly in shock and mostly excitement. She lay on the bed and I spread her legs to taste her sweet shaven pussy. She started to moan and was trying to grab my cock. I ended up turning round and lay over her in a 69. After what seemed ages licking and eating her sweet juices, I turned round again and entered her. We had a great rythym going with her moaning in pleasure before I couldn't take any more and pulled out and came all over her tits. There was more spunk than I can remember me making in those days. "Now" she said, "that was your starter, when I need some attention I expect to get it" We never quite had it that good since but she has wanked me off several times since and even now in her 80's still enjoys seeing my hard cock and giving it a stroke from time to time.
