Over the last month or so (which means having sex about four or five times for us...) I have been pumping on a more regular basis, and most times pumping right before we are having sex, or as part of foreplay.
During this time I have also noticed a few things that have been different when my wife has been giving me blowjobs. I have noticed a drastic change on how she is blowing me. She has always been more enthusiastic about giving me oral sex when I am enlarged from pumping, but recently she seems to have several new and amazing techniques that are absolutely fantastic feeling. Everything is different, from her pace, to how she is using her tongue, to giving a lot more attention to my cock head, to how she sucks me, to how deep she is willing to put me down her throat, and how long she is doing it for! I asked her about it and she said yes that she had tried a few different methods she intentionally researched and read about. She made mention of how large my cock head was now and that she was able to play with it more in her mouth with her tongue and teeth, and that my cock fills her mouth up so much now with my size she really loves that feeling. She told me she has never been this turned-on while giving head before, and she wants to keep learning and improving and doing it more often.
Several times during this period she has also called me over to the bedside and gets on her back with her head over the edge of the bed and asks me to face fuck her. This is something she knows I have always loved doing (that open path straight down into a woman's throat in this position, and the ability to come into the void at the back of her throat, is one of the greatest feelings to me...) and always had to ask and negotiate to do it; she had been pretty reserved in allowing it to happen (birthdays, special occasions, drank too much...) She is now offering that position to me on a more regular basis, and is allowing me even deeper into her throat and actually gagging on my cock (gagging was something that always had to be avoided and was a huge turn-off for her.) I also asked her why that it was OK now and what was driving her new interest in that position. Again she told me it is the feeling of being that full from my larger size, not only in her pussy but also in her mouth and throat, and that feeling is intoxicating for her.
I asked if it felt like she was with a different guy (when we have sex after I pump I often ask her to fantasize about my larger cock being on a different guy), and she said some of it is that, but mostly it is more of a different "me" to her. Familiar, but with new exciting benefits.
So I am definitely going to keep pumping!
