Have her suck your dick while Sarah and Mrs Wright clean each other up a bit...

Your dick is once again rock solid from the sheer sight and thought of Laura being there. She comes over and kisses you on the cheek then slowly kneels down.

She starts to lick the head, and slide her tongue down your shaft. Your classmate seems to know how to give head by the feel of it... Then then engulfs your cock down her throat and starts to slowly move back and forth occasionally letting your dick out her mouth so you can see the head shining from her mouth's work.

Laura starts playing with your balls, first time you've had this done and you like it. She begins to pick up the pace while Mrs Wright comes from behind you and wraps her arms around you. Pressing her naked body to yours. She starts nibbling at your neck, while Laura is picking up the pace.

You can feel your climax approaching, what should you do?
