I was happily married until me ex-wife decided to try pastures new and left me a year ago. I miss her but to be honest, life was too comfortable and t...e sex predictable.In contrast to my slim, good looking ex, I'd always had an eye for a divorcee who wasn't hard on the eye and attended to same drinking hole as me. Fortunately the feeling was reciprocated and we eventually ended up in bed. No big sparks but it was exciting at first.As our relationship progressed, Susie (for that was her name)put. I’m so hot; I’ve never felt this way before.Then I feel your cock up against my slit. You are rubbing it all over me. I feel another tingle go down my spine, knowing I’m about to be taken for the first time, by my big brother. You continue to kiss my back….one hand on my clit…and the other guiding yourself into me. First just the head. I get used to the feel of it, and you slowly start to move, the water still beating down on us. You move deeper, and deeper, until you enter me completely.. He growls at me "Come here!" I obey immediately, thinking I am in deep shit. He sits himself in the chair, and grips my hand, yanking me closer to his side. I stand there, swaying a bit, before he booms "On your knee's!" without thinking I immediately obey, before I think to question why, he pulls me by my waist, over his lap. I gasp, but before I can say anything he spanks my ass. I scream in pain, he didn't hold back at all. I don't understand what's happening! He's never done anything like. Then the worst thing happened as the door opened and auntie Jean walked in. Robbie grabbed his trousers but auntie had clearly seen everything including his erect cock.Robbie just kept apologising, 'oh auntie I'm so sorry, it's very naughty of me, sorry.'He started taking the panties off and was about to pull on his trousers and suddenly auntie said, 'Don't be silly Robbie, leave them on, you obviously love the feel of my panties.'She went over to him and reached down and felt his cock through.
