#401295 - I couldn’t help it but rest my hand on her arm and start stroking her soft skin in a circular motion, I moved further up until my caressing was right next to her tit. Peaking through the balustrades, I stopped dead, the living room was in darkness lighting wise except for the TV, it’s a large screen about 54 inch I guess, the room was lit with a bluey glow and to my shock grandad sat in his recliner, dressing gown wide open, revealing him wanking the biggest cock I had ever seen! I licked my lips in excitement as I then realised he was watching porn, an old man had a young girl spread out on a table and he was finger fucking her bald cunny furiously. He obviously had the sound muted as I could not hear anything but imagined what her copiously wet cunt would sound like as he rammed his fingers, knuckle deep in and out of her twat.
