Custom vid request: So you would be dressed as that sexy nurse with the tight short dress that shows very well your lovely big breasts. You come on house visit for sperm clinic donor that cannot make the trip over. "you also told the doctor you have difficulties getting erections and cumming? Well don't worry... I am trained to make any guy cum. But since we cannot go several times on home visit, you will have to deliver all your samples right now in 1 go. What? You think it will not be possible? Oh honey, you have no idea. I have just about the right tool with me to make sure we get the very maximum out of you and not waste a drop. But you will have to be strong because it might be though to have so many orgasm on short time but thats the sacrifice for the money you'll get for your donation... You WILL deliver untill i'm satisfied. " you roll in vacuum cleaner, bend way down reaching for it while flashing your naked pussy under your dress/skirt, plug it in and switch it on lower or medium power at first. You bend over/sit facing towards his cock showing your cleavage (boobs almost jumping out of dress but still contained), get his dick out and suck the dildo head with the short hand pipe without attachments. Do this with some very nice and long sucking actions (5-10 seconds or longer each time) with dildo head blocking pipe so vacuum makes loud motor **** sound please (very important to me!!). After few minutes he already cums, you keep the vacuum on the head to catch up all sperm not wasting a drop. "ok that was one, you enjoyed it right? But this will not be enough, i will need much more and bigger cumshots".You bend down and turn the power control of vacuum cleaner to very FULL MAXIMUM POWER (very important!!) and make sure suction control slider on tube (if there is) is fully closed for maximum suction. He begs not to post-orgasm-torment his sensitive cock but you reply "lets get all out... I need it, you understand... So don't fight". You place the vacuum tube firmly on the dildo head for many long sucking actions so motor reaches full speed and vacuum power builds up (min 5-10 seconds every time... Longer when cumming), the vacuum cleaner Yelps so loud trying to suck the sperm out through his cock... After a few more minutes he cums hard again squirting into the vacuum cleaner tube. You turn off the vacuum cleaner to watch the sperm inside the tube... If it comes leaking/dripping out of the tube when you hold it down, you have extracted enough sperm. If not, switch on vacuum and carry on vacuuming his sore cock untill he squirts so much in the vacuum that it drips out of the tube when you cut out vacuum just after cumshot. "thats a good boy, i finally can leave satisfied. Thank you for your cooperation and donation. You leave him and his soar cock alone and walk out.
