Tři centimetry široké velké černé dildo ničí můj šťavnatý zadek zezadu

I've been trying to get used to my new dildo more and more, but each time it seems to never fail in wiping me out & giving me quivering assgasms! It even leaves my tailbone aching for days after! In any case, the pounding is well worth it to me, can't wait to eventually go up another size! Please tell me any recommendations you may have for my next video!
