Is it normal to not warn your partner when you're about to cum in their mouth?
it's a dick-ish thing to do but she doesn't like it so instead of warning her, i just blow my wad in her mouth (she eventually realizes i'm cumming and pulls away). i'm always on my back when she gives blowjobs so due to gravity she doesn't have to deal with too much cum getting into her mouth but it turns me on immensely doing it because she's such a prude and i bet people who know her wouldn't ever guess she takes cum in her mouth niyla (and her face at least that, she willingly does, thank God)
it's NOT something she HATES and she really has no real reason for not liking it other than she's a huge prude. so i even the playing field by putting on my "silencer" (where i don't make any sounds when i'm cumming so as to not alert her styers) and just shoot off into her mouth for those first few seconds where she's totally unaware
