Flashback: Another discovery

He grabs Sarah around her waist, and heaves her onto the bed, still face down. So far so good, what now?

A little devil in the back of his head. Why not get a little something out of this, why not take advantage of the situation, and check out Sarah, her tits and her pussy? Its the opportunity of a lifetime. Turn her around! Just to make sure she is okay of course!

Too aroused to think clearly, Adam quickly succumbs to temptation and slowly turns his sister around. First, he checks her eyes: Still closed. Her mouth and full lips: Still breathing, still moaning! Then he lets his gaze drop lower, ogling her pair of big breasts. He didn't know, that Sarah was gifted with such beautiful, big, round and full tits, probably an E or F cup. Then, as he lets his eyes wander even further, to check out her pussy, he is shocked and gasps. His sister has a huge cock! And it starts to rise and point upwards. Its tip already slick with precum. A long thick shaft. Apple sized balls! A clean shaven pussy, with wet swollen red lips. The first real pussy Adam sees in his life. Right below his sisters huge cock. Why has his sister a fucking huge cock?

He tries to understand: His sister. Her pussy. Her balls. Her dick. The pills. The bottle half empty. His sister. Big balls. Huge dick.

It makes click. The pills! They work!
