It was the middle of summer and our BBQ season was in full swing.  My husband loved to have people over to eat drink and be merry.  I would run around keeping everyone’s happy whilst my husband and his friends drank loads of beers and cooked food on the BBQ. 

My son Mark and his friend Paul would often help me with the plates, glasses, cups etc bring them into the kitchen so I could wash them ready for the next round of drinks or food from the BBQ, people always seemed to put their plate down then wonder off and forget where it was. 

I noticed Paul would always walk behind me checking out my big ripe ass, or stand just in front of me as I bent over so he could see down the front of my top and get a better look at my very large white volumptuous breasts.  I would quite often stay bent over for longer periods than needed when no one was around to allow him to get a better view of my assets. 

I thought it was a harmless bit of fun, and I wasn’t hurting anyone as he didn’t have to look if he didn’t want to. 

Things changed halfway through the day as I noticed Paul would keep sending my son off to the far end of the garden to collect things so he could follow me into the kitchen and get me on my own for a while, first he just rubbed his hand or arm lightly against my butt cheeks or breasts, but then as I bent over on one occasion he actually ground his cock into my butt cheeks as he squeezed past me.  His cock felt large and long as it pushed deep in between my half open butt crack.  I didn’t move or say a word.  I just kept loading up the dishwasher as if nothing had happened. 

About an hour later I could tell my son had been drinking, he was unsteady on his legs and his speech was slurred.  I helped him into the kitchen and asked who had let him have a beer, he just laughed and said he had been collecting the half empty ones when he cleaned up and just poured them into a glass. 

I looked at his friend who was not hiding the fact that he was now checking out my breasts as they pushed out from under the work apron.  I asked if e had been drinking and he smiled and said no chance he was enjoying himself without the need for booze.  I told my son he should go lie down for a while until the booze wore off.  Paul said he would help him and grabbed his arm and helped out of the kitchen and off upstairs to his bed room. 

After about 3 minutes I felt Paul move up behind me as I was clearing off the plates into the bin, he wrapped his arms around mine and pushed his semi-hard cock deep into my semi open butt cheeks.  He startled me which caused me to jump, allowing him to rub his hands over my breasts and give them a quick squeeze whilst doing so.  It also caused my bum to push backwards onto his cock, which now started to grow at an alarming rate.
