Alone Right Now

My wife is watching tv. I went to be early cause I have to get up early for work. I couldn't sleep so I read a few stories on here. I'm super horny now! 

I dont want to cum yet. I'm just enjoying being horny! I slipped the waist of my boxer-briefs under my balls so all my junk is hanging out. This feels so good. 

I'm still not ready to jack off yet so I'm grabbing my scrotum, lifting it up and letting it drop. Fuck it feels good! I wasn't too hard but now I'm sporting a full erection. 

I'm just running my thumb up and down the top of the shaft now. Fuck I'm so horny! My sheets are wet from my pre-cum! Wife is def going to smell that when she comes back to bed...

What should I do next?
