. on with the story.It was during school holidays and it was pretty warm, even without the presence of the sun. I came in from being out with my frien...s and when I walked into the living room, Mark was there. I was a little shocked to see him and was told to sit down. I was getting a little scared, had Mark come clean? However my worries were misplaced. My parents and Mark explained that he had won a holiday for 1 week in Menorca. He had two tickets and claimed he didnt have anyone to go with. But he wanted me to dry him & then he would dry me up. I said ok do it but fast. Now he got the chance to grab the boobs properly but above the bra. So he started squeezing them with the towel. Oh what a feeling was that. Then I quickly dry him up. Now he wanted me to change his clothes as well. I said ” Alright I can do that for you but I won’t allow you to do the same. He tried to convince me but I didn’t got agreed on it. He said ”Fine my beautiful sis, atleast you do it me “. As I put his. Rob didn't hesitate, but he was a little unsure all of a sudden. He wasn't all that concerned about people looking at him. He knew he wasn't small or had anything to be ashamed of. The funny thing is that the first that came to mind was "What if my dick gets sunburned?"Once his swimsuit was off, he figured a benefit of this is that he'd get his wife to rub lotion on his manhood. He took the lotion and resumed between her legs. Marni always got hot when Rob touched her between her thighs near. Suddenly Mary released me from her mouth with a slight pop. She stood, removed her panties and facing away from me, lowered herself onto my hot hard 'dildo' as she liked to refer to my shaft. Sh slowly began to raise and lower herself on me and every time she lowered her self her wet cunt engulfed all of me. I was in heaven, with her sliding her hot pussy up and down my stiff shaft and Bud sucking and nibbling on my nipples I was almost ready to cum. Mary could sense this and began moving.
