I reached there in 20 mins and waited 10Mins before approaching her house. I went into her place in exactly half hour and she opened the door. She loo...ked at the watch and said I am impressed…. Exactly half hour. I like people who are punctual. We walked around her place as she was showing me the window frames in the bathrooms and all I could see was only her ass!!! It was looking so inviting that I was loosing control. I was just staring at her ass while following her and we entered one of the. I looked threw her draws and I found what I was looking for a bra. I wanted to see what size her boobs were. So I grabbed a red bar and I look on the tag of it and it said 38C.I still had that boner so I started to jerk off with her bra and a pair of her dirty thongs from her hamper. About 15 minutes later she walked into her bedroom and saw what I was doing. Then she asked me if I would like to see her model in her bra and thongs.As a 18 year old male I said yes! She came back out and spun. We stood there with our feet just in the sea and Colin came over to us and said are you 2 enjoying yourselves, yes very nice I replied trying not to look at his cock, we are probably going to head back are you coming or staying for a bit, no we will come back too. So the 3 of us went back to Sue and got dressed and left the beach. AS we walked back to the hotel we passed by a restaurant and sue said we are eating there tonight if you want to join us, we had looked the first evening at it and it. I could see the bulge of his cock harden in his work trousers as he looked down at it. He grabbed my hand and put it on his crotch and I started to rub all around. His hand slid down to my own bulge and started doing the same getting me rock hard straight away. He laughed and said I was keen and I know not what he means but he explains 'You like it..your dick likes that yeah?' I nod again, understanding now. He reached down and undid the button at the top of his trousers and slid my hand in,.
