As we sat outdoors just finishing having our lunch the front door bell rang, Holly jumped to her feet and ran to the front door to answer it.
"I hope it's her friends or someone's in for a shock." I said laughing, then added. "She's forgotten that we're all still naked."
We all were still laughing as she brought her friends thru the house and out to the pool.
"Everyone this is Nikki and Steve, Steve was my teacher at school." Holly explained.
Emma always a show off stood up showing of her naked body to our visitors, both Nikki and Steve stared at her checking her out from head to toe, Emma walked towards them and gave them both a kiss on the cheek.
Then told them. "I'm Emma, Holly's sister and those two dirty old men sitting there are my father Mal and my granddad."
Everyone broke into laughter and as our new friends joined us at the table, Mal and I were checking out Nikki she had blonde hair and nice big what looked like D-cup breasts hidden under her top. Holly noticed us staring at her friend's Nikki's breasts.
"Are you coming in the pool for a swim." Holly asked Nikki then added. "I think dad and granddad want to check out your breasts."
Nikki laughed and stood up and said. "Ok." Then lifted her top over her head to reveal a pink bikini, when she slipped her shorts down to her ankles we saw a matching pink bottom bikini.
Holly reached out and unclipped Nikki's bikini top and told her. "You don't need to wear these." Then untied the bikini bottom ties letting it fall to the ground.
Mal gave a wolf whistle as Nikki did a full circle turning around showing off her naked body to us, her pussy had a small bit of fur above her slit and her nipples were big and long. Mal jumped in causing a large splash covering everyone, then Nikki dived into the water coming up close to Mal, then Emma jumped in holding her sister's hand.
We had been told by Holly that they were in their late 30s but Nikki could've passed for one of Holly's school friends. I watched Steve undress and when i saw his thick nine inch cock Spring free from his swimming trunks, I looked at Mal and we looked at each other's smaller cocks, his cock made ours look small compared to his.
Holly had told us they had a young daughter and I quietly asked. "Where's your daughter today?"
Steve told me. "We dropped her off at her grandparents on our way here."
I had a chuckle to myself, thinking how I was called granddad these days.
"Your welcome to bring her with you for a swim next time you visit." I whispered to Steve.
Steve smiled at me and said. "Yeah that sounds like a plan, Nikki works on school holidays and I have to look after her by myself. It would be good to have someone else to help me take care of her."
Steve watched as I stroked my cock and he started stroking his.
"Fuck that's a nice cock you have." I told Steve
"Thanks , I guess Holly told your were both bi as well." Steve told me
