Touch them both
From Create Your Own Story
You walk into your bedroom and remove your clothes, laying them on the edge of your bed. You then lay on the bed, your right hand taking hold of your 7" cock, and the left hand inching down to fondle your twat. Your hand move in unison, stroking your cock, and rubbing your slit. You shift onto your right side, reach your left hand around your leg and shove two fingers in your pussy. Your pussy is so moist, it's almost dripping onto your bed. You continue to pleasure yourself for a few more minutes, gradually increasing your speed. As you stroke harder and finger faster, you inch to the edge of climax, until you explode your juices onto the bed, leaving hot cock cum in front of you, and sweet cunt cum behind.
In hindsight, maybe the bed wasn't the best place to do that, because now you have to change the sheets for... ya know... in case she's actually into you having both parts. After you've finished with the bed sheets, you must decide what to cook. But for God sakes, remember to wash your hands first.
