ok well I haven't shopped for such toys to get myself off I'd have to get creative around the house. I took a hot handle holder and lined it with a sandwich baggie filled with lotion, creating a nice, slick orifice. Rather than jerk myself off with it though, I inserted it between the sofa cushions on the couch to keep it in position. Then I just kneel down to the opening and deliver!
I've also got off on cups of jello and I also used this packaging wrap not bubble wrap but similar that it was air-filled pockets of lined plastic. Poured some baby oil on my dick and wrapped it around it..got me off just fine!
