Since you and Sarah have been together Mel her mother has always seemed to be really nice to you, she would touch your arm in a flirtatious way when ever you say something remotely funny, also if you were round when ever she was doing some cleaning she would always find a way to bend over in front of you to pick something up giving you a nice view of her amazing arse.

Mel is 38 and very attractive she has small breasts around a 36B, a small waist but a very tight firm arse that you'd love to get your hands on.

Mel is married to Martin and he is Sarah stepfather.

One day you go round to see Sarah. As your approaching her front door you receive a text message from her that tells you -

"sorry babe I've had a nip our for a few hours, I'm going to see my nan at the home but you can wait for me at my house if you want my Mum and Martin are in, see you soon baby, love you xxxxxx"

So you carry on and knock on the door,
waiting a few moments and eventually someone answers the door, it's Mel wearing a dressing gown "hey John come in" she says excitedly, you enter noticing her smooth long leg slipping through the gap in her robe.

Mel then tells you "go and sit in the living room and watch some tv if you want, Martin's still asleep he went out last night I think he's a little rough" which then you proceed to the living room putting on the TV and then slouching yourself on the couch.

"Would you like a something to drink John?" Mel asks,

which you reply "yeah sure can I get a cup of tea please Mel"

After Mel has brought in the tea she sits across from you, and you two starting talking, and you seem to notice that her robe has fell open, though still covering her breasts you notice that Mel's legs keep opening and closing noticing her white slightly see though panties and catching glimpses of a camel toe, this starts to make your dick bulge, so trying to be as casual as possible you pick up a cushion and place it over your lap.

Ending the conversation Mel gets up tying her robe as she does, saying "I'm just gonna get changed John" she leaves the room, a few moments later you realise you have to get up to pee.
