So far it had been a pretty incredible summer. I'd met Mary, fucked her alone and with the local stud Curly, decided I was bi, and found out the old man was also bi and that he was rooting his best mate. Things were all good though, especially between me and Mary. We were getting on so well that I decided to bring her home to meet my dad and his girlfriend, Inga, for dinner.
I ended up having a job interview the day of the dinner, so Mary was going to come around a bit later, but Inga piped up that she could pick her up on her way home and Mary could help her prepare. It was just dad and me in the house for a long time and Inga said Mary might need a bit of "girl time" before she sat down to dinner with the likes of us.
I should probably explain a bit about Inga now. She's this redhead, mid-30's, smoking hot, spends all her time either at work baking or at the gym. Totally upbeat chick too, very friendly and happy. If Dad hadn't nabbed her I often reckon I would have had a go at getting her. I figured Mary would be alright alone with her, she's not exactly intimidating.
Anyway, I got home from the job interview and, just out of habit, went in round the back. I hardly ever use the front door at home, never have. Walking round the side of the house though means you go past the kitchen window. I was gonna tap on the glass and keep walking, just to freak the girls out a bit, but then I looked through the window and saw them.
I couldn't believe my eyes.
There's Inga, my old man's girlfriend, with her head in Mary's crotch. Mary was up on the counter-top, legs spread wide, clothes off, head rolled back, just loving getting her snatch eaten by another woman. I knew Mary was pretty open sexually and pretty out there but I didn't figure she'd do this! And Inga was a total surprise, I had no idea she liked box.
I should have made a noise or gone round the back or something, but I was staring, transfixed. This was clearly not the first time for either of these gals. Inga pulled her head away from Mary's cunny and went to one of the drawers. Mary, completely starkers, stayed seating on the benchtop and picked up a glass of wine. She took a sip and put it back down as Inga came back... with a wooden spoon.
Mary rolled over onto the benchtop and arched her arse up in the air. I think she was expecting Inga to spank her, but instead, Inga grabbed Mary by the hips and drove her tongue into her arsehole. I saw Mary's eyes widen with excitement. I remembered to try that one next time we were together. After a while, Inga brought the spoon up... and ran it up and down Mary's pussy, pushing it in ever so slightly. Then, once it was good and moist, Inga changed tactics a bit. The spoon came out... and she pushed it against Mary's eager, tight arse. Mary nearly fell off the bench she backed up on it so fast. With one hand she started to flick her bean while Inga worked the spoon handle in and out of her backside in slow, steady strokes.
