"Ok, I have wanted to do that with you for a while"Before she gets on me she sticks that dick back in her mouth. I lay there just enjoying the pleasur.... She licks all her juices from before and finally gets on my dick. I lift her shirt and she takes out her tits through her bra. Now they aren't the biggest tits in the world but good enough to grab and grab hard. She takes control of the motion and speed. She is grinding as hard as she can."Oh fuck! That feels so damn good son!"I don't say much,. He had been gone three nights which was the most they had been apart since their wedding. From the shy virgin at the wedding, she had learned to enjoy sex and the separation had her dreaming about it in her sleep.But this night she was awakened in the wee hours and realized that it was not a dream-erection sliding in her yoni. It was not her husband’s either! It could only be her father-in-law that had come up behind her as she slept and raised her sleeping garment. She pretended to stay asleep. I must say I was immediately turned-on when I saw him, before finding out who he was in the grander scheme of things, but ashamedly, I did have the odd wet dream, and secret tryst with my finger, as I mentally submitted to his advances, and his huge penis of course.Of course mummy was none too happy by his reappearance, but when I walked in on them having a good roll on the living room carpet, I guessed mummy had forgiven him, or his cock at least.Most c***dren balk at the thought or in reality. .but then I just came out and said it (we'd both just had a pretty detailed chat about fucking the life out of our friend's sexy mum, so i thought whats the worst that could happen)... 'we have about another 10 minutes until they all get back, I'm going upstairs to wank into these panties, you can join me if you want?'. As i stood up and opened the living room door my mate said to me, 'sure, i'd fucking love to put my cum in her worn knickers!'. We both went upstairs into the master bedroom.
