It was at this point that the moment was ruined, the shrill ring of the phone snapping us back to reality. Once he answered it and I realised he was actually talking to my sister, his wife, I began feeling slightly naughty. As he continued talking on the phone to his wife, I started flicking my fingers across his cock, occasionally stroking up and down before moving onto wrapping my mouth around his quickly hardening cock as I sucked as deeply as I could, moving my head up and down while taking a lot of enjoyment listening to him trying to hide his moans of pleasure while he was on the phone. His wife, my sister, talking to her husband, blissfully unaware that he was sat on the sofa with her younger brother, both of them completely naked and his cock pushed into her brother's mouth.
Once he found an excuse to quicky wrap up the phone call so he could hang up, I continued for a few more seconds so he could enjoy the feeling while also being able to let out the moans and gasps of pleasure before i stand up in front of him, my hard cock at the level of his face.
I told him there was one more thing he had to experience but we would need to wait for a time when my sister wouldn't be walking through the door any moment, only for him to tell me that she had said on the phone that she would probably be stuck at her friend's for at least one hour if not more.
Needing no further convincing, I told him to stand up and follow me, walking upstairs together as we made our way to his bedroom. I instructed him to bend over the bed with his legs spread so I could work my tongue and fingers around and inside his tight, still virgin arse, covering it with my spit as I made sure he was fully wet in preparation for what was to come.
He let out a gasp of pain as I pressed my cock against his arsehole, pushing into him slowly, bit by bit, not once stopping as I listened to him telling me it was hurting him, that he didn't want me to fuck him, he wanted my cock out of him which I replied by saying he was entirely in control, if he wanted me to stop, all he had to do was stand up and I would pull out. Obviously, that never happened and I continued my push into him, listening to his protests and desire for me to stop, not once standing upright though as was explained to him.
I hadn't really thought about it beforehand, and it wasn't until my cock was completely inside him, my legs pressed against the back of his legs and my balls hanging down against unexplored crack of his arse before I realised I hadn't put a condom on first, I had my cock inside my brother in law and I didn't even have a condom on. That thought, however, was quickly replaced with the idea that, if my sister let him have sex with her, he must me fully clean and it wouldn't be risky if I continued.
After letting my cock sit inside him for a few seconds, I began moving back and forth, my cock sliding in and out of him, listening to him go from sounds of pain to moans of pleasure, stopping only so that I could turn him over and lay him on the bed on his back, his legs propped on my shoulder while I continued fucking him, my hand stroking his cock with the same tightness as his own arse and the same rhythm with which his arse was currently being fucked |
