My mother in law has always been quite affectionate towards me,always a kiss on the lips hello,even the odd squeeze of my ass,i dont mind as she is discrete,and a bit of a milf aswell.We were all going on a family holiday down the coast,but myself and my mother in law were to meet everyone else down there acouple of days latter,due to work committments.She suggested i come over for dinner and we leave from her house early the next morning,i agreed.When i arrived i found her out the back in the spa,champagne in hand,she asked if i would like to join her, i said shaw i will get into my swimmers,no need she said,stairing at me as she hopped out,totally nude,she came over to me,my jaw still on the ground,our normal hug and kiss hello became a sensual kiss and carress,my hands seemed glued to her hot ass.She went to get me a drink as i undressed and hopped into the spa,she came and hopped back in the spa beside me,handing me my drink,my hand rubbing her uppper thigh,then her clit,she closed her eyes and groaned with delight as i worked on her pleasure button,i felt her hand grasp my now throbbing member and she worked it expertly as i slid my fingers inside her.She pushed me away and moved to the opposite side of the spa,telling me how wrong this was,but then presenting her beautiful ass as she hung over the edge of the spa,fuck me hard was her command,i obliged.Sliding my cock into her beautifully shaved pussy,i pounded her doggie style,my balls slapping her ass as she moaned with pleasure,not caring who could be listening,she shook and screamed with delight as she came very hard,turning around, she told me to fuck her mouth, hard,she wanted to taste my cum.I fucked her mouth hard and deep,she took all of me ,occasionally gagging ,i thrust into her mouth as she grabbed my ass hard with both hands,digging her long nails in as i came in her mouth,she swallowed every drop of my cum as she deep throated me,we collapsed into the spa to rest,the night had just begun,round 2 was in the lounge room,3 on the balcony,4 on the dinning room table and round 5 in the master bedroom,needless to say our plans to leave early the next day didnt happen.
