Stacey went to take a shower, and I watched her heart shaped ass as I lay back on the bed. I wanted to smack her juicy rear, but decided I would do that later, preferably whilst I fucked her from behind.

'You like my sister's ass?', Lorna said, one long leg thrown over me.

'Not as much as you like her tits, apparently.'

My wife laughed at that, even whilst she played with my cock.

'You think you're the only one who likes sucking her tits? And no, I'm not bi. And no, I've never been with anyone else. But when Stacey turned 18, we started playing with each other a little.'

'I had no idea.'

'Obviously. But when we both got boyfriends, we moved on from that. But tonight, seeing you going at her, well...it got me going too.'

'It was fucking hot,' I said honestly. 'I nearly came when I saw what you were doing.'

'Oh yeah?' Lorna said, 'First you come down my sister's throat. Now you nearly came on her bed. I'm sure you can think of a better place to shoot your load.'

'Lorna, are you really ok with all this? It doesn't worry you, what we're doing?'

'No, it really doesn't. Me and Stacey have been talking about this for a while. Tonight was a set up, you know that. When Stacey rang and said you'd turned her down and would never cheat on me, the final piece fell into place.'

'The final piece?'

'You, dummy. Your faithfulness in the face of temptation. Plus, Stacey has been in love with you for years. Couldn't you tell? You just needed my approval.'

'I don't know what I've done to deserve you. Or your sister.'

'Well this guy has a little something to do with it,' she said, squeezing the head of my cock.

'I love you, Lorna.'

'And I love you. That's why this is going to work out just fine. Now shut up and eat my pussy.'
