Added commentary

“W-what would you say to her if she was watching? If we recorded something or if she was in the room?” you asked, your voice starting unsteady as Grace kept her lips wrapped around your cock.

Even when she pulled off to answer, one of her hands quickly moved in to start jerking you off again, giving you no rest while your sense of touch was heightened without your vision.

“I’d tell her… Mommy’s sorry for stealing away your boyfriend but I really, really need this right now” Grace replied, a hunger in her voice that told you she was a lot more turned on with your teasing than you had expected.

She gave you one long lick from the base of your shaft, all the way up to the tip before she went back to taking you as deep as she could go. You could swear you could feel her sigh in relief once you were back in her mouth but you quickly got preoccupied by the pleasure and gave up questioning everything.

Without being able to see, your thoughts switched back and forth between Emma watching you and Grace right this very moment and just how you imagined Grace looking as well. With Grace on her knees, you couldn’t reach out to grope her body but you rested a hand on her head as she bobbed up and down. That only added to the image in your head as you now had another way to track how far she was actually managing to take you into her throat.

Everything she did was driving you crazy and with the blindfold, the loss of a sense seemed to amplify everything else. You wanted to rip it off to finally get a good look at her but even moving from where you were felt like you would lose your concentration over the situation.

You wanted to try and add more for her in the experience like with the dirty talk but she was bringing you to higher highs than you could function at, her tongue working its way around your shaft whenever she took you deeper.

Eventually, it got to be too much as the pleasure spiked at your point of no return, giving you only the briefest moment to warn Grace that you were going to cum. Even without the warning, she had been reading the signs and pulled her lips back off your shaft and quickly stroked you off when your climax started, your first rope shooting out and hitting something you couldn’t see.

Her hand kept wringing out more and more from you as she directed you to paint her body, making small changes to where she pointed your cock that you were still oblivious to.

Your whole body was tense as you came and only when you felt completely drained from Grace’s fingers did you allow yourself to breathe and sink back into the chair, feeling like all your energy had been sucked out of you.

It didn’t take long for you to recover but in that time, all you could hear over the sound of your own breathing was Grace. She was doing something and after one loud swallow, you were positive she was feeding herself on your cum, an image too resisting not to try and look at.

“I know what you're doing so the blindfold might as well come off” you stated, showing off that you had caught her even if you weren’t completely sure.

“...C-can you see through that?” Grace asked, the sound of her movement stopping after you spoke up.

“No but you weren’t exactly being quiet about it. It’s all I can hear and I’d much rather watch you than just listen” you explained, hearing silence again in return.

You felt her hand reach up to undo the knot she had tied and it came undone rather quickly, the blindfold falling away as if you could have taken it off at any time if your trust in her had faltered.

Your reward for having faith in her was the sight of Grace sheepishly looking up at you, naked on the floor of her office. Her cheeks flushed at the compromising position she was in and you could clearly see a streak of cum on her chest that had had a finger run through it.

As she was sat down you couldn’t see all of her hourglass figure but just solely on the look she was giving you and everything that your eyes were able to leer at, you couldn’t believe you had somehow managed to get with a woman like her, let alone her agreeing to share you with her daughter.

Even with whatever she had already gotten rid of, you had completely coated her chest and you could see a line running down her chin from where another rope had landed on her.

The sight made your groin twitch even without the effects of any passives, something Grace spotted just as quickly as you did. You knew she hadn’t gotten to cum yet and to you, that meant the fun wasn’t over.

With the blindfold still in one hand, you leaned forward in your chair to get closer to Grace, you used your other hand to wipe a new line in your cum that streaked her chest and held it up close to her face. You could see her swallow in anticipation before you brought it to her lips, watching them part as she started to suck the cum off of your finger.

She closed her eyes out of embarrassment with you watching her so closely but you knew she was getting off on being looked at.

“How about you have a turn next?” you suggested, getting her to open her eyes as you gestured towards the blindfold.

“..what if…” Grace started to say, looking over at the locked door and answering her own question before she even got to say it.

“Same rules you gave me.” you said, taking each end of the blindfold and holding it up for her to decide on.

“Okay…Yeah, let’s do it” she replied, meekly at first but getting more pumped up after she had admitted it to herself.

With her still on the floor, you stood up and reached out to pull her to her feet, not letting her get very far away from you in the process.

“Before that…” you added, noticing you were still half dressed in comparison to Grace.

It didn’t take long for you to strip off the rest of your clothes and you didn’t feel the need to hide the fact that you were naked from Grace before the blindfold went on, letting her know that you weren’t limiting your options once she could no longer see. The one thing you did keep track of was your phone, making sure you knew where it was instead of just throwing it away with the rest of your clothes.

You directed her to turn away from you and carefully placed the fabric over her eyes, tying the knot behind her head with just enough strength for Grace to feel the pressure of being tied up.

You spent a moment admiring her from a step away, leaving her standing on her own while she knew your gaze was on her.

“Oh, this is better than I thought” Grace admitted out loud, her thighs rubbing together as her kink started getting the better of her.
