Always let them know, they can make their choice... unless its just an anon fuck in the dark who wants to take it raw no questions!
Met a couple of virgins who wanted me to fuck them bb, explained everything to them n they still wanted it, one said he was going to get fucked raw anyway, and accepted he would be pozzed at some stage! Other didnt want me to cum inside him, explained he could still get pozzed from precum, he still wanted me to pull out until he felt me swell inside, then asked me to shove it deep! I obliged! I just took my time breaking into them, soon had my balls slapping as they moaned, both came back for more, one became a real btm slutt taking any raw cock n cum loads. Other likes to be fucked raw long n slow in 1 on 1 sessions and has learnt how to use his ass to milk cock, takes multiple loads in a session, flips n fucks like a rabbit as ur juice drips from his asshole!
