"Oh yes we know Scotty very well. Tanya spoke before Scott had a chance.
He is in my Photography/Art course that I run at TAFE. Jane and I pose nude in front of him all the time."
"It's the first time he has watched us have sex though." Jane broke away from Tanya's grip.
"Oh come on Miss Jane, since when have you been so prudish? Tanya reassured her. This is a sex beach after all. So how do you know our Ruby?"
"I met Ruby and her family right here yesterday." Scott explained.
"So you have already met the family, you don't waste anytime do you?" Tanya laughed.
Scott turned bright red, Ruby helped him lay his towel beside her and they cuddled. Jane was much more relaxed now and Tanya invited Ruby to have a threesome with them.
"Sure I would love to show Scott how bisexual and sexually active I am. As Scott's cock jumped to attention at the thought of watching her have a lesbian threesome. I'll be there in a moment. You two start without me and Ruby began to give Scott an intense blowjob in front of her family. Scott I think we both need to cool off before I have sex in front of you, come for a swim with me naked." Scott chased after her into the surf.
Not five minutes later, Ruby felt Jane massaging her tits and fingering her in the surf. "You ready for your threesome yet.?" Jane whispered in her ear.) Jane carried her out of the water.
"Rescue me my prince" Ruby laughed, as Scott chased them up the beach.
Tanya was eagerly masturbating in anticipation of her sexy niece joining her lesbian threeway. Tanya gave Scott a handjob, leaving her own sex on her hands, as they watched Jane licking Ruby's tight young pussy. "Let's show young Scotty just how intense lesbian sex can get!" Tanya winked at her niece. Tanya started to gently roll the tip of her tongue over Ruby's erect nipples, then started to suck and lick Ruby's tits picking up the pace as Tanya sensed her nieces orgasm. Tanya and Jane assumed the scissoring position and rubbed their soft shaven together vigorously, as Jane replaced her fingers inside Ruby's pussy, where her tongue had just been.
Ruby reached over to hold Scotts throbbing erection. With love in her eyes.
"Enjoying the show young man? Tanya asked Scotty erotically. Tell us how much you love Ruby?"
Scott just nodded as his eyes were popping out of his head in disbelief at his luck. "Wow this is so hot, Scotty thought to himself. I adore her with all my heart." Scott finally managed to say as the two love birds gazed into each other's eyes.
It was as if they had the whole beach to themselves, paying absolutely no attention to the rest of their family and on lookers. I just smiled at them and thought I couldn't wish for a better Mother's Day present.
