She does quite well

Already fairly experienced from previous times you had fun together, courtesy of the gun causing changes, Steph gets off to a fantastic start, making you moan as she uses only her hands, caressing your body and making you feel amazing with every inch her fingers go over. Clearly, she knows exactly what it is she is doing.

"Mmm, yessss, perfect, Steph, you're getting better with every time we do it", you tell her in between your moaning, and she seems to be pleased to hear that, redoubling her efforts to give you pleasure, which have an immediate effect. Te entire apartment is filled with your moaning, almost as loud as Steph's was when it was you giving her pleasure.

Your mind is blank, nothing inside it beyond bliss and the pleasure your roommate is giving you, doing her best to give you as much pleasure as she can, eager to remind you of why she is is your roommate and you love having her around. Looking up at her, you smile between moans, pulling her in for a kiss while her hands continue to work their magic. It really is amazing just how good she is, but she did learn from you, so it makes sense, especially with how well she knows your body.

Returning the favor, you give her some pleasure back, but still let her take the lead, as it is her turn, and you don't want to take than away from her. Soon, you feel your pussy heating up even more, feeling the orgasm coming as you moan, and finally come, squirting all over Steph's hand as you do.

Then, fully in view of you, Steph starts to slowly suck each of her fingers, cleaning them of your juices and swallowing them in a very hot show just for you. Slowly, you catch your breath as this goes on, and finally get up, wondering if you should go to work or show up fashionably late after a bit more fun with Steph.
