I’d volunteered to cover them with sunblock and that was what I did. I played special attention to their ‘delicate’ parts and while I was betwee... their legs I twisted the vibrators to start them and slowly eased them in. Both girls moaned as I pushed them in as far as my middle finger would let me.“Right ladies; who’s doing me?” I asked.It was joint effort but Zoe turned up the egg before she started and I had my first beach orgasm of the day with then knelt either side of me.“‘Priapus’.” I. She responded very quickly we continued for 10 min and then I removed her t shirt and pressing her big boobs hugging from back side. She was in black cup bra… And I took off her bran and started sucking her right boob and pressing other she was slightly started her moan..Again I started sucking her lips this time very long time we exchanged our saliva, she was very hungry and I was feel her heat of the body… Mean while I put my hand on her pussy and rubbing. She said yes go on…I took off her. To further mess with her twelve year old sister’s head I linked her to all of the feelings her sister and I were both feeling as we fucked. When her sister came, so did she. When I started to fill the middle sister up I was staring into the younger girl’s eyes as she tried to push away the ghost she was feeling pushing down on her as he came. Her eyes went wide when she realized it was her sister’s pussy that was making hers squeeze in climax around my spurting dick. I gave her a big grin when. My suit is black and hers a deep blue. We both are wearing men style shirts, deep green for me and royal blue for her.Her long legs are sheathed in sheer nylons and she's wearing towering heels that I daren't attempt to wear. I realise that I've been staring at her for so long she must think I've been struck dumb. However after spending three days at a business conference, and sharing a hotel room with the straightest of straight lady's, I'm working on a philosophy of if you can't touch then.
