I walked up into the bedroom while she read/studied/dozed and I placed my cock onto her book.  She quickly took it into her mouth and it grew to 100% stiffness in no time.  I played with her titties just a bit after unbuttoning her top but as soon as she cupped my balls and I could feel her fingers on my taint/ass I knew I could blow at any second.  She would have been okay with taking it into her mouth but instead I backed off and filled her cupped hands.  Then I rubbed her back while she came quickly and strongly.
