Go with it. This woman's alluring as fuck.

I knew that this Karina woman was about sex, but remembering my encounter with Crystal, I wanted to be careful not to impregnate some random sex bomb in the belly of a train. But man, all of a sudden this felt real, and I was into it. I wanted to see what Karina could do next.

I let the thong slide over the obstacle of her melon-shaped ass and drop to the wet floor.

"So," she said, "It's been a while since I've had a good cock like this." I cringed. I wanted to fuck this woman so badly, but it was time to tell her that vaginal was gonna be a no go, as I still had no condoms.

"I don't have a condom," I said apologetically.

"Relax," she said reassuringly, "We can put it in my butt." She said it like it was as commonplace as suggesting where to eat lunch. The fact that Karina threw around the idea of anal so easily caused my boner to surge, raging in Karina's hand.

Karina, taking short, sparse breaths, turned around to face the shower wall, one hand still stroking my cock. With the other she turned the shower on. At this point I was still naked, and she was wearing just the tank top and push-up bra underneath. Hot water hit us, creating a soothing steam in the room and soaking Karina's white top, making her already prominent tits even more visible as the water stuck the thin white garment to her shapely rack, further defining her curves.

With one hand she braced herself against the wall and at last she released my cock, cramming her hand into her pussy, riding her fingers up against the wall. I stroked myself as I watched, getting more turned on with each hump and moan Karina gave. After thirty seconds or so she reached her hand back, grabbing my cock once again, and began to guide it to the tight hole between her plump ass cheeks.
