Head and the gf close by

ok,so I just sucked a random guy in my driveway,while my girlfriend of 12 years slept like 30 feet away,I havent had a cock in my mouth for about 3 years and keep asking her to do a threeway with us and another guy,but she says I only want that so I would have an excuse to mess with another girl.Truth is I dont care,guy or girl,I love sex...a nice hard cock squirting in my mouth,a nice freshly fucked pussy oozing with cum ready to lick clean,to me sex is sex,raw,animalistic passion,it's all good and I love it but I just wish she could feel the same about sex as I...it's just sex,not love,not a commitment,just sex.I do however respect her opinion and do not try to force anything on her,if she some day says..I'd like to try something different,fine by me! =)
