Is there any way I can simulate real sex with my suction cup dildo without riding it on the wall or bouncing? I'd love to somehow do doggy without needing to use my door.
Without purchasing anything else it is very unlikely in my mind. I do know someone with a dildo on a (long) stick but this still requires effort on your part (or a second person)
You could purchase a sex machine or Lovehoney have a range of thrusting toys which won’t be hands free but will provide the thrust action. https://www.lovehoney.co.uk/sex-toys/vibrators/thrusting-vibrators/
