Nipple-kneaded life with older girlfriend who teases her nipples until ejaculation

[Posted by male college student: Mr. Q] My girlfriend is a beautiful, stylish, and has a great girlfriend with a lot of adult sex appeal! But...I'm an abnormally fond of nipples and when I have time, I rub, lick, and suck my nipples, and I'll be forced to get an erection... My nipples are so throbbing, I feel like a girl's pleasure like a rampage from the tip, and my nipples are stimulating by my girlfriend, and I'm forced to cum inside her every day with her hips shaking violently... I can't get any more than just my nipples anymore.
