She has several.

The goth girl continues to smirk as she watches you and Erica.

"Well, I'll give you a few ideas to help in the bedroom, but if you're comfortable talking about it with me, I'd like to make sure I've got a decent understanding of what you're looking for."

Her attention is back on Erica fully at this point, as if guessing who is making all the decisions at the moment.

"That's fine." Erica is calm, blunt about her willingness to share any embarrassing information about your sex life with her.

"Alright, so first point is...his dick's not doing it for you?"

She doesn't look surprised when Erica nods.

"And the two of you had the best sex of your life so far while sharing a dick?"

Erica nods again, and you flush as you realize that someone of the customers wandering the store probably got the wrong idea from that.

"Got it. Well, first off, you'll probably want a nice double-ended dildo. That's no problem. A strap-on cock would be nice too. He could wear it over what he's got and pretend to be a real man. You could attach it to his head and ride his face. Or you could just fuck him with it...it's not as awkward as the double-ended one, even if only one of you can get fucked at a time."

Erica looks disturbingly interested, and to your humiliation, you feel a small tingle in memory of the pleasure of having a dildo hitting your prostate.

"On top of that, we've got vibrators, cages you can lock up little useless dicks in, gags, restraints, you name it. We even have a room in the back for...trial runs, if you're interested."
