Ask to watch

"Sorry, just heard some noises...," you start in an apologetic tone.

Wait, does this count as free-use? Charles said you could use any woman you wanted, like the one from the shop you tested it out on. But right now you were just barging in on them, it's not ok unless you're sexually using the-

Hold on. That's it.

"Uh, you mind if I watch you two while you do it?" you finish your sentence.

"Um, I guess that's fine," Melissa says.

"Oh, John, you know it's fine to watch, just don't sneak up on us like that" Lilly says with a sigh of relief.

Both girls trained their eyes on one another once again and begin to kiss each other.

Hot

Melissa spreads her legs as Lilly suddenly leans in and places her head in between. She begins to lick her as Melissa tilts her head back and closes her eyes.

Your friend's girlfriend was cheating on him one room over, and to make matters worse (or hotter), it was his little sister who she was cheating on him with.

As Melissa moans softly you pull out your hard cock and begin stroking.

You surprise yourself with how often you can get hard again. This wasn't normal... but that's a question for another time

As Melissa lets out a sound indicating she just had an orgasm. A few loud moans later, she switches to eating out Lilly,, who's face was now glistening in female juices. Lilly places her hand on the back of Melissa's head and casts her eyes downward.

You walk closer while continuing to jerk yourself off.

As you take a look at Lilly's pussy, neatly trimmed to a landing strip you admire her nearly naked (save for her pasties) body.

Lilly suddenly looks up at you and notices you, placing her hand on your cock before turning her eyes back down on Melissa.

You grope at Lilly's large and pleasant breasts. She seems to not mind, all her attention on Melissa.

Suddenly you feel yourself about to cum, and you aim your cock at her breasts for her second round of cum. You start squirting your cum over her boobs, but just as much seems to hit Melissa's hair and face, and she suddenly pulls back from Lilly.

Oops.

"Oh John, uh thanks" Melissa simply says.

"You're not done yet Melissa" Lilly says as she pushes Mel's head back down to her waiting pussy.

Melissa's cum covered face goes back to work on Lilly's pussy, as Lilly lets out a long moan and Melissa's face emerges wet, cum covered, and with a smile.

You watched as both girls collapse on to the bed, sporting your semen and each other's wetness on their bottomless bodies.

You quickly, and shamelessly snap a photo with your phone.

Lilly notices, and throws another pillow at you before setting back down.
