Aika Yamagishi lives with an older girlfriend who tortures her nipples until she ejaculates

[Posted by Mr. Q, a male college student] My girlfriend is beautiful, has an outstanding figure, and is the best girlfriend with a lot of adult sex appeal! But...I like nipples to an abnormal degree, and when I have free time, I rub, lick, and suck my nipples, and I get a strong erection...My nipples tingle, and I feel like an electric shock is running from the tip, making me feel like a girl. I feel like this, and every day I have to force my girlfriend to cum inside me by violently shaking her hips while teasing my nipples as she gets horny. I can't cum with anything other than nipples anymore. *The contents may differ depending on the distribution method.
