Seduced by my Daughter's Best Friend

Ally is a long-time single, divorcee and wonders where her life has gone as she watches her daughter, Josie, and her friends enjoy a final summer pool party before they head off to college. It seems like just yesterday that she was young, free and had everything ahead of her. This reminiscing makes her have a few more drinks than maybe she should... and maybe just a little horny after so long without loving touch.
And when did Kirby, Josie's best friend since elementary school, become so damn hot? In that skimpy red bikini, Ally can see the girl has developed into a gorgeous young woman with full curves and a beauty that is certainly going to break some hearts at college. As Ally is packing up the sun loungers into the pool house, Kirby joins her to help. Even though they have known each other for years, Ally senses a tension in the air, the spark of desire.
The girl is nervous and wants something...  And then Kirby makes a move on her! Ally has never thought about being with another woman before and certainly not one half her age! But she hasn't been loved for so long... and she is drunk... and horny...
