An Unexpected Summer House Guest Experience

Part 1 1st 3 some. I've been reading so many different stories on here about people's first wild experiences. I've decided to tell mine. I was an 18 year old boy. I had a number of women and girls tell me that I was very handsome and really cute. I was tall and thin, short blonde hair, a very smooth body, a pretty big dick and a nice little bubble butt. I was seeing a girl my age who lived a few blocks away from me. We had been friends since we were in grade school. She was 18 and she was so beautiful. She was short with brown hair. She had such a sexy body. She said that a few times there were older guys that said she had such a gorgeous ass. The summer we turned 18. Her parents went away on vacation for 3 weeks and she had her house to herself. She invited me to stay with her for the 3 weeks. So she wouldn't be alone. I was excited for multiple reasons. I got to her house right after her parents left. Her parents had a pool and a jacuzzi. As soon as I got there. She wanted to go in the jacuzzi. I changed in the bathroom and she changed in her room. I finished before her. I was waiting in her living room. When I saw her coming down the hallway in her new bikini that I've never seen before. I couldn't believe how sexy she looked. She was wearing a white 2 piece bikini. The top was smaller than her tits. It was only a little bit bigger than her nipples. Her nipples were hard and showing through her bikini top. The bottom had a little piece on the front that was really tight. I could almost see her pussy. She stood in front of me and she asked me what I thought about her new bikini? Then she turned around. Her ass looked so amazing in that bikini, wow. It was almost like a thong. It was a small piece in the middle and it was wedged in between her ass cheeks. I got so hard. That's when she looked back. She saw my shorts and that I was hard. "Oh my God. Do you have a hard on from looking at me?" I smiled. I can't help it Stacy. You look so freaking beautiful. And with that bikini on. You look so freaking sexy. Then she asked, "Can I see it?" She had a devilish grin on her face. She came closer to me. "I'll show you mine if you show me yours." I pulled my shorts down to my feet. My dick was sticking straight out and it touched her. Well, one thing led to another and before much longer we were both completely naked. That was our first time sleeping together. For the next 3 days we never put any clothes on. We had so much fun together over those 3 days and nights. The 4th day me and Stacy were still naked. We were on her living room floor 69ing. All of a sudden as I'm eating her pussy and she's sucking my dick. We hear the voice of a man. We both stop and we look. Standing right next to me and her is a big older man. When me and Stacy first saw him. We were both scared. We both sat up and she moved as close to me as she could. I asked him, what are you doing here in her house sir?! Her father has owed me a lot of money for to long. Now it's time to pay his dept. My father isn't here sir. He's away on vacation. So you 2 are here by yourselves? Yes sir. He sat on the couch and he said if we do everything he says for the rest of the day. He will leave after that. If we don't do everything he says. He won't leave and he will make it very tough for us. Does that sound fair to you both? I said yes sir. Stacy said the same thing. Good. I want you both to keep doing what you were doing when I first got here. Me and Stacy got back into the 69 position with me on the bottom. He was watching the entire time. Then I felt his hand on my ass. And I heard him say, wow, I'm not sure who I like more. You are both so cute and sexy. As Stacy is sucking my dick. I feel the older man's tongue on my ass. He pushes his tongue in my ass hole. For a moment I was nervous. Then, as Stacy keeps sucking my dick. While his big wet tongue was deep in my ass hole. I couldn't believe how great it felt.
