We finally turned in and Richard joined me in my bed and Jennifer slept with Lisa.
We could hear the girls talking and playing so we sneaked a peak at the door.
We watched as Lisa got on her back and Jennifer mounted her. Jennifer picked up a huge vibrator, which was thicker than Richard's cock, that Lisa had out and spread Lisa's legs apart. We heard Lisa telling Jennifer to stick it in her cunt and fuck her with it.
Jennifer slowly inserted the vibrator in Lisa and started it up as she slid it in my beauty's cunt. All we heard was a low hum but we could see that Lisa was enjoying the vibrations. It didn't take long before we heard Lisa moaning as she was having her orgasms. As she was, we could see Jennifer squirting milk from her tits all over Lisa until she had nothing left.
We quietly tip toed back to my bedroom.
Richard and I had huge hard ons as we got into bed. I moved my hand down to his cock and grabbed it and started jerking it. He did the same to mine. Richard then asked me to fuck his ass and he got on all fours. I inched up behind him and angled my cock to his hole and started penetrating it. He kept pushing back until my cock was fully seated.
I started pumping my cock in his ass and reached down to play with his balls and cock. As I fucked him, he started jerking off. In no time, I shot my load in his ass and then my limp cock fell out of him as I laid on my back.
Richard now faced me and aimed his cock at me as he continued jerking his cock. I grabbed his balls and felt that he was ready to cum. He finally shot his huge load all over me, including my face, hair and mouth. As he finished, he fell on his back spent. We both fell asleep covered in cum with our bodies pressed together.
The next morning Richard and I woke up to the smell of coffee. Richard and I jumped in the shower and got all the dried cum off of us then went into the kitchen to the girls.
They said they had a great night and we said the same.
Just then, Richard got a call on his cell phone. We heard him say ok and hung up.
He looked at us and said that his young 18 year old sister, Dina, is coming and he had to go and that he would call us later.
Richard and Jennifer went home and straightened the house out as Dina would be there soon.
The problem was that Dina was not a nudist nor a swinger and this could pose a problem.
Richard got a call from the gate that Dina was here. Richard put shorts on and went to get her as Jennifer put some clothes on.
Richard picked up Dina and brought her to the house and along the way, she saw a few naked people but didn't say anything.
They arrived at the house and Jennifer met them and helped them with her belongings. They put Dina in the spare bedroom and got her settled in. Dina congratulated them on their marriage and the baby.
Once she was settled in, the three of them went into the kitchen to talk.
Dina started the conversation by saying she missed him and took a leave of absence because she needed some time to think. Richard said he was happy that she came but he reminded her that the resort is a nudist resort and that they don't wear clothes most of the time.
Dina said she knew and decided to try being a nudist, if that was ok with him. Richard said being a nudist isn't for everyone but if she wanted to try it out, he and Jennifer would help.
They explained the rules of the resort which she was comfortable with. They also told her they would introduce her to their friends and make her feel comfortable as possible as a nudist.
She thanked them for everything and then asked what was next. Richard looked at Jennifer who told Dina that all her clothes had to come off and he and Jennifer would be taking their clothes off too.
Now, understand that Dina was now 18 and Richard had not seen his sister naked since she was a pre-teen so he was a little nervous.
Jennifer took Dina to the bedroom and watched as Dina removed her clothes. When she undressed, Jennifer let out a gasp. Dina was drop dead gorgeous and so sexy without clothes on. Dina had a perfect pair of tits with full nipples and a beautiful smooth pussy. Jennifer then took off her clothes and the two beauties stood naked.
Jennifer asked her how she felt being nude in front of her. Dina said that it wasn't as bad as she thought it would be and felt comfortable,
The two women came out of the bedroom and saw Richard naked from behind. When Richard turned around, Dina just stared at Richard's cock and said, Oh my god out loud. She told Richard she never saw anything so beautiful and turned beet red.
