Go to the bathroom and get a surprise

So you go the bathroom to relieve yourself as your about to finish and shake, The door bursts open with Mel standing there
"oh so sorry John I didn't know you were in here"

Standing there like a deer caught in headlights with your 9 inch cock still in hand, she glances at your member which seems to last forever but in reality was just a few seconds, she then turns around closing the door behind her.

You ponder to yourself did she see, did she enjoy the view.

You then go back down the stairs to the living room trying to be casual and not letting the event which just happened enter your mind. But its not that easy because Mel is now wearing a very tight and short white dress that ever so slightly reveals the bottom of her arse cheeks.

"John so are you joining us for Auntie Karen's 50th birthday party tonight?" giving you a wink as she says.

"yes of course Mel I wouldn't miss it for the world"

Mel then slowly walks past you brushing her hand against crotch as she does.

This makes you instantly hard, no longer knowing what to do with your hard on you try to stick it into your waistband.

"ok John me and Martin and just going to pick up Sarah from the home, we'll be back soon"

"Ok no worries see you soon"

So now your left alone in your girlfriends house with a massive hard on.
