Yes, and she wants to reward you

"Oh Carl, that was so... gooooood..." Amy half-moans.

"Does your back no longer hurt?" you ask, still a bit concerned if you did it right, but happy that she really liked it.

"It didn't hurt that much to begin with," she confesses, blushing a bit, "but yes, all the pains are gone now. And I'm so relaxed..."

You just sit there, looking away and smiling a bit awkwardly, and with a raging erection in your pants because she is still almost naked in front of you.

Suddenly, Amy suggests, "Would you maybe like me to return the favour?" You look her in her grey eyes, and you could swear she was just looking between your legs.

"You w-want to... m-massage me back?" you stutter a bit , because most of the processing power in your brain is already in use for imagining possible scenarios that could come from that. That includes Amy "massaging" your dick with her womanhood. Needless to say, you can't strip right now without revealing a huge boner. Although you start to think that she wouldn't even mind seeing it.

"Maybe not just your back," she jokes, "but yes, I really do. I want to thank you for your hard... work." As she says hard, she looks deeply into your eyes and tilts her chin to her neck, making her look devious. You are not imagining that.

Amy smiles, and her tone changes. "Just get rid of your clothes, and then come lay next to me. I won't look! I already prepared a towel for you, there, on the other side of my bed." With that, your friend closes her eyes.

Doing as she says, you nervously strip off your clothes, down to your underpants. Although Amy seemingly has her eyes closed, she didn't turn her head to the other side, so she might be sneaking peeks at you. Who knows? Who cares?

You lay down on the left of Amy, cover your underpants-clad butt with the towel, and bury your face in the soft pillow. You push against her arm as a sign that you're ready.

A squeezing sound. Amy moves slowly over you. A moment of silence... and then her warms hands moving softly across your back, oiling you up.

She increases the pressure, which surprises you, but it's actually quite good. The idea that almost-naked Amy is willingly giving your body this sensual attention turn you on so much that your body almost starts balacing on your erect cock.

You start to get really into the massage, but then...
