Self Suck Sort-Of

So my roommate was out with his girlfriend and would be sleeping at her place. Friday night I was on my own again and rather than go out with some friends drinking, decided, since it was raining like mad that I'd just stay in and get stuff done then relax. So after a quick dinner I did a load of laundry, then dusted and vacuumed my room. After I finished I put on some music, popped open a beer and sat back in the Barco-lounger in the living room. After about 15 minutes, I though, "why not?" got up, stripped, sat back down, reclined, put down the beer and took hold of my penis and started to masturbate. I got into it a bit before thinking I should get some lube so got up went back to the bedroom got the lube from the nightstand drawer and then noticed the vacuum I'd not yet put away. So I picked up the vacuum on the way back to the living room and remembered how when I was younger I'd tried to get a vacuum to suck me off, then how I'd been able, later, in college, to suck myself off. Not having found the vacuum to have worked too well and no longer feeling quite flexible enough (or daring enough) to try blowing myself again, I was putting vacuum away when I noticed the rigid extension tube that attached to the flexible hose to reach under furniture and stuff. 

I wondered... 

So I got back on the recliner, put my feet up on the footrest so my knees were raised, put some lube on my penis which had gone soft in the interim but had quickly begun to respond to my touch, lubed one end of the extension tube, then leaned back, reached down and maneuvered the head of my only half-hard penis into the mouth of the tube, put my mouth on the other end...and inhaled and slupred my dick right up the tube. 

Whoa!

A little exhale and it was pushed back out. Inhale...shlooop! Up the tight, lube-slicked tube again. 

Oh, boy...Suck, blow, suck, blow, suck, blow...suck. I'd gotten too hard to come out again. I waited a few minutes until I felt myself softening. Not yet, not yet...OK. Sluuuurp! 

Oh, fuck!  Suck...wait, suck...wait, suck, suck, suck!  I was hardened up again and again I stopped and waited. A couple of minutes, and I started to soften. 

SUCK SUCK SUCK!

I repeated this two or three more times, then let myself go almost completely soft, then sucked my penis up the tube one last time. 

Suck...blow, suck...blow, suck...blow....suck, suck, SUCK, SUCK, SUCK...

Oh, fuck, I'm gonna....oh, wow... I'm cummming!

I sucked my dick hard into the tube as I orgasmed and could feel myself straining against the smooth wet walls as I ejaculated, the did the suck and blow as I started to soften almost unable to take the over-stimulation of the the tight tube on my now overly sensitive penis.
