Yes

"Oh god." Your mom moans. "I feel like a cumrag. My throat feels like it is about to be broken, and flooded with cum. Please fuck her, Derek. Fuck her like the slut she is."

You begin slowly thrusting into Selindra. Hearing both women moan, and before you can really react, you know that she has also made it to where Penelope doesn't care about the sounds of sex coming from your room. As you pick up the pace on Selindra, you notice that your mom has begun to masturbate. She removed the straps of her top from her shoulders, and is twisting a nipple while her other hand is down her pants. Selindra is also writhing beneath you, as you pound away at her hungry cunt. You can feel the urge to come, and you can barely make out Selindra telling you to come in her within all of her moans.

When you finally burst, you can feel Selindra's pussy clamp around your dick in her own bliss, while your mom orgasms as well.

"That felt incredible," your mom says. "How did you make it to where he came inside of you, but it wound up in me?"
