On a pretty regular basis even with a girlfriend that has sex with me all the time there are times when I just like to handle myself. Its these times I get my anal T vibrator, the Boy Butter, and lay back on the bed with a good bisexual porn and give myself a full service masterbation. I slide it in and out not missing a stroke along with my cock.
    

Sometimes I'll even take the strap- on my girlfriend uses on me strap it to a chair and ride it till I just explode a massive load of cum sometimes makeing a big mess all over myself. Then there is the times my girlfriend comes in takes her pants off lays on the bed faceing me and starts rubbing her clit makeing my masterbation even better! Than again usually when she comes in the masturbateing does not last much longer befor we start rubbing and finnishing off each other. Thats a whole different story for another time though.
