Nipple Tease

You have come away for a little break with your best friend and his girlfriend Sophia, when you pop round to their motor-home to see what your friend is up to you find Sophia on her own. She invites you in for a cup of tea, she is wearing a small purple silk dressing gown and when she bends over her tits fall out revealing her big pink nipples. She asks you if you like what you see and when you say yes Sophia instructs you to take your dick out and have a wank over her while she teases you.
