black dildo and panties

i previously posted about my gf making me wear little boy undies and little pink panties while witholding sex from me. after a nigh of wearing pink boyshorts she refuses to undress and makes me jerk off in front of her while she watches and ridicules me for being so tiny. once i do come she makes fun of my tiny load. we recently got into a black lex steele didlo that is MASSIVE. i love to watch her come over and over powering that huge black cock inside her. i am here to ask for some new ideas because this same routine is getting a bit old. i want her to ice my prick and balls so they shrink, maybe a chastity device, maybe some IR porn. any hot ideas will be appreciated and i will try them all. thanks ladies and cucks! attached is a pic of the panties she powers me into while she plunges that big black cock into her.
