CMSND: Riley Mirror Fun [Sequence] By Doc000 (Patreon)

You've seen the first panel already, but I got Doc000 to add a 2 more and round it out into a sequence.

"Riley got a bit too worked up after the shagging she gave herself in the mirror, and grew a dick as a result. She lets lust get the better of her judgement, and starts having a yank right there. As she's finishing off, a familiar face walks right into the line of fire. The professor seems strangely okay with all this however..."

A bit more crossover between Riley and Doctor series. I wonder what will happen next?
