Susan sees it too and offers to help. You don't really want any help but she gets down on her knees in front of you and pushing your knees apart. "I can see what the problem is," she says with a giggle. She tells you to lift up as she slides a finger right through the gusset to pull it down and it makes it a lot easier. The problem is that when you sit back down Susan keeps hold and you suddenly realise that she is pushing her fingers into your pussy.
You try to push her off, but she just laughs and then you realise that Andrew has seen what she's doing and before you know it, she's got her other hand wrapped around his cock. Scared and excited at the same time you soon feel your climax beginning to build, but then she pulls her fingers out, stands up in front of Andrew and pulls the front of his shorts down.
She looks across at you and shrugs. "It'd be a shame to waste it," she says and climbs up on his lap and sits right down on top of it making him gasp. As you watch your best friend bouncing up and down on your brother's cock you use your own fingers to get yourself off.
When Susan climbs off Andrew's lap, you can see his cock has gone limp and there's a dribble of spunk coming out of the end of it. He tells Susan he's sorry and I guess that she is the only one of us who didn't have a cum.
