She asks Mara to join her in the bathroom.

I turned to Mara and asked if she needed to use the restroom. She looked a little apprehensive, then noticed the bulge beginning to form in my crotch and quickly agreed. The huge breasted Asian girl followed me to the nearest toilet and began to pull my pants off. “I don't know why you hide your monster from everyone else,” she said as she began to pull my semi-hard foot long cock out, “Some of the other girls would love to ride this monster.” As she began to pull off her pants, my cock swelled to its full twenty inches, which looked ridiculous on my five foot two frame. Her own cock was hard, but next to mine, her eleven inches seemed a little small. She slipped off her panties and kneeled in front of my massive boner. Her attempts to swallow the head of my penis were in vain, as always, but she was dripping wet, so she pushed me back onto the toilet and climbed on top, her pussy directly in my face. “Lick it, I need it to take your beast,” she panted as she fingered herself. Holding up her cock with my left hand, I dove in, her smooth crotch glistening wet. As I licked her, she shivered and I brought my huge cock head up to her waiting lips. She lowered herself onto the massive pillar of flesh, slowly, wincing slightly as it split her pussy lips further and further apart. Her hips bucked as I began to feel more resistance at the tip of my huge rod. I could trace a distinct bulge along her abdomen with my finger, and as I did, I felt her clench along the length of my entire cock. Mara had put a hand over her mouth as she came, trying to keep relatively quiet. I was getting close to cumming as well.
