For us it really depends on what we feel like that day. We like strap on play, and we love the RodeoH panties with the Tantus silk, Tantus P spot or a glass toy. We also have the funfactory share which is a lot of fun during pegging.
My girlfriend loves the Jimmyjane Form 5 vibrating on her clit while I use my fingers in her vagina to massage her G spot or just holding it there during sex.
We also love glass toys, I am very much into having stuff in my bum as it can increase my orgasm a lot. The smoothness of glass and how easy it is to insert with a bit of lube means I find it great to use.
Being tied up, spanked with a paddle, is something we both love to give and receive. So we really like a lot of variation! Gotta try them all to find out what we like/don't like is kinda what we are going for!
