Sister-in-law's blowjob

This is a true account of my first blowjob from my sister-in-law.

This true story happened in 2005 when my sister-in-law came to our house. My wife was at work and I knew she wouldn't be home for another couple of hours. I told my sister-in-law this, but she said " That's okay. I need to see her anyway so I'll hang around if that's okay with you." I'd always got on really well with her and her husband so I told her it was no problem, plus I'd always fancied fucking her as she had great tits and fantastic body, but never tried anything on, as she was my wifes sister, and didn't want to jeopardise mine or her marriage.
On this particular day, we were sat at our table talking when my sister-in-law suddenly leant forward and put her face in hands. I asked her if she was ok and she said she had a headache. I told her that I'd read that headaches start in the back of the neck and asked her if she wanted me to massage her neck to see if helped. "If you think it will, I'd love you too" she said. I stood behind her and gently started to massage her neck and along her shoulders. "Oooohhh, mmmmmm, that feels lovely and it seems to be working" she said. While I was massaging her neck, I had a birds eye view of her cleveage and tits going up and down with her breathing as she was wearing a low cut top showing her ample tits. "Keep doing what you're doing. My headaches almost gone and I love the way you're touching me" she said.
Being brave I said " Happy to oblige, besides I've got a great view of something else I'd love to touch" "Do you mean my tits" she said. "Errrmmm, yes, does it bother you" I said. She gave a little giggle and said "You pervert, no it doesn't bother me, what else are you going to look at. I think my headaches gone now, but don't stop, I'm enjoying this". I kept on with the massage but started moving down towards her tits, eventually sliding my hands into her top and bra and started to squeeze and rub her tits and nipples. " Ooooooohh, mmmmmm, that's nice. I love my tits being played with. They're so sensitive, mmmmmm, don't stop, please don't stop. I love your touch." I pulled her top and bra down so her tits popped out and were in full view as I groped and kneaded them. I stepped to her side and bent down, gently sucking each nipple in turn as my sister-in-law had her head back, eyes closed gently moaning as I played with her tits and nipples. I moved round and swung a leg over hers so that I was straddling her. "What are you doing?" she said. "Weellll, your just at the right height " I said. "The right height for what?" she said. I bent down and kissed her and she kissed back. "For you to use this" as I touched her mouth "To use on this" I said pointing to my cock. "You want me to suck your cock" she said. "That's exactly what I want you to do. In fact, in time I want to fuck you and I think you want me to" I said boldly. " Can you read my mind" she said as she opened my jeans reaching for my cock. " You're right, I do want to fuck with you and have done since we met" she said as she took me deep into her mouth. As she sucked noisily on my cock, I carried on mauling her tits making her moan. As she sucked harder, I started to rock back and forth, practically fucking her mouth. She was and still is, a fantastic cock sucker and it wasn't long before I shot four long streams of cum down her throat. She swallowed every drop not missing a beat. "Mmmmmmm, that was lovely, need more of that" she said. "Anytime you want it, just let me know" I said. We tidied our selves up and carried on talking, which was just as well, as my wife came home early. Before my sister-in-law eventually left for home, I told her to come over on Saturday as my wife was going to Sheffield to a concert and would be out from 09.00 til about 2 in the morning. She asked me why I wanted her to come over (as if she hadn't guessed), "So that I can get you naked and fuck your mouth and pussy till you're sore and can't fuck no more" " Dirty fucker ....... looking forward to it, our first time" she said. If you want to know what happened that day, leave a comment and maybe I'll write it, but as a little teaser, it also involves my wife.
