Lauren has gone to see Matron after her sports class; she is still wearing her sexy little netball dress with white ankle socks & trainers. As she waits for Matron she starts to flex her biceps, her arms feel tight & toned after all the catching & throwing and she wants to admire her muscle definition. As she flexes her arms she touches her biceps, they are looking nice and as round as she tenses & relaxes them. Lauren flexes her biceps one at a time then both together, from the front and the back, giving you a nice little show. She even kisses her biceps leaving a naughty red lipstick mark on each!
