Anal
I like to watch porn or read stories on solo to get really horny and wet but I try not rub my clit or pussy so instead I go and run a bath and grab my sisters dildo, I get all settled in the bath and start slowly stimulating my ass hole so it relaxes and then slowly insert the dildo right up there, I take it in and out sliding it gently when all of a sudden waves of pleasure rush over me. I get my best orgasm that way.
Make sure you know all the safety crap about anal masturbation.
HAVE FUN!
