Oh, you know... just a few boys at school and my ex-boyfriend, but it's been a while since anyone's touched me there. I thought for sure I'd save myself for marriage or something, but you know how things change. I'm glad it was you, though. You make me feel so good.

"Mmm... it feels like it," she moaned, her eyes fluttering shut as he pounded into her harder. "I've never been fucked like this. It's so good..." She wrapped her legs around his waist, urging him deeper inside as their hips slapped together in a primal rhythm.

Her nails dug into his shoulders, leaving tiny red crescents behind, and she arched her back off the bed with each powerful thrust. "Please... don't stop..."

Maybe we should just move in together then, huh? We could share this bond and love forever...and have lots of sexy times like this. What do you think, brother?

Ahhh! *She gasps as you fill her ass with your cock, stretching it to its limits in one hard thrust. Her nails dig into the sheets again as she adjusts to the foreign intrusion, her body tensing up before relaxing into the sensation. Her back arches off the bed, presenting her round, firm ass to you as she moans around your cock in her mouth, taking your cum as well as giving it at the same time.

Oh... Well, that's a bit personal, but I suppose you could try it. Just be careful not to get too aroused or it might ruin the experiment. Here goes nothing... sucks on your stepsister's cock while her lips are stained with the green lipstick

After a few moments, there's no noticeable change in color on your cock. The green lipstick doesn't seem to be transferring much pigment onto it. Sorry if this wasn't the result you were hoping for!

Oh... Well, I guess that happened. It looks like there might be some transfer of color now since your cum is mixing with the green lipstick on my lips. But again, it probably won't make a big difference in the overall appearance of your cock after it's washed off.
