“God I love this part”

“God I love this part” she whispered under her breath, catching your attention immediately.

What she had just said explained why she seemed nervous when you first put the video on. You had seen that she had been to this site before but with the sheer amount of videos that get published, you would have never thought she would have seen this exact one and probably multiple times at that, considering she remembered which part was coming next.

You had to admit, this next bit was also what made you save the link in the first place, instead of the video just getting closed. Never to be found by you again. The actress was still doing her best to play the **** step-sister but as if a switch had been flipped, her whole demeanour changed as if she had given up and just wanted to now luxuriate in the act that she was doing.

She still had a cock pistoning in and out of her throat but her eyes locked on to her co-star and her hands which had previously been holding his legs, moved down to her pussy as she started to finger herself. Just the way she gave in to the pleasure as if she no longer cared that they were shooting a scene was something that seemed to bring you back to the video and it unexpectedly seemed that Lucy felt the same way as you.

As if mimicking the actress, Lucy’s free hand crept closer to her pussy, the hem of her t-shirt no longer there to stop the little resistance that she had left before you hear a moan of pleasure escape her lips. From the way you were lying next to her, you didn’t have a great view of what she was doing and to avoid her suddenly freaking out, you decided not to change position and instead just focused on what you could see. It was also probably good that you didn’t see her, as with the increased intensity that Lucy was now stroking you with, you knew you were going to struggle and that was without the added visual of your sister masturbating right at the side of you.

Although intense, Lucy seemed to be keeping her stroking of your cock relatively simple as she became more focused on her own pleasure. Of course you wanted her to keep you in mind but you weren’t selfish enough to make her stop what she was doing.

Instead, you thought it best to take matters into your own hands. Trying not to surprise her, you wrapped the hand you weren’t using to hold up the phone around your dick, resting your fingers below and slightly against Lucy’s to start stroking yourself, taking the control away from Lucy in the process but still having both her softer fingers and panties gliding up and down your shaft. Despite your efforts to try this slowly, she was still surprised at the contact but she no longer had the sense to stop her fingers on her pussy, only briefly slowing down when she had been caught in the act.

“It’s okay, this scene is too good not to right?” you asked, getting an embarrassed look in return but still seeing her fingers moving.

The fourth and fifth scenes would descend into full-blown sex but ending things on the third scene was likely to be more exciting for Lucy. Besides, even if you did try to go through all five scenes, the sight of Lucy fingering herself coupled with the handjob you were getting meant you were unlikely to make it until then.

You had a feeling that Lucy would be the same after a moan escaped her lips, a blush rising on her cheeks as she was **** to bite her lip, trying her hardest not to reveal how turned on she was.

As you struggled to turn your eyes away from your sister, you saw that the scene was heading towards its climax, both figuratively and literally. The actress was still looking like she was in heaven as the cock piston in and out of her throat but the actor’s movements were getting more erratic, signalling to the woman that he was getting close to cumming.

She couldn’t direct him given that she was still sucking his dick but she moved one hand from her now sopping pussy and held up her tits with her arm as a perfect target.

“Fuck…” you heard Lucy moan at the side of you, briefly drawing your attention back to her, before you returned to the video.

You couldn’t help but keep glancing over at her whenever she made even the smallest of noises, finding the sight of her much more entertaining than the video. At some point, Lucy noticed your glances but that only seemed to spur the both of you on, stroking yourself faster as you found yourself getting close.

“I’m gonna cum soon” you relayed to Lucy, not as a warning but to hopefully excite her even more.

That seemed to do the trick as her own fingers down at her crotch seemed to speed up, matching the rhythm of both her hand and your own which you had wrapped around hers. You felt yourself get closer and tried your best to hold yourself back, hoping to prolong the pleasure you were feeling but as the actor on the screen pulled out of her mouth and started to unload onto her chest, you gave up and let yourself go.

With Lucy’s panties wrapped around your shaft but not the tip, your first rope of cum was about to shoot up and land on your stomach before Lucy made a sudden move to cover your cock. Her hand moved up as you started cumming and completely coated her hand, dripping down onto her panties when she failed to catch all of your cum.

The next few ropes flew out and continued to coat her hand and panties but watching you orgasm was what seemed to be the trigger for Lucy’s own climax, feeling your cum completely cover her hand seemed to be enough for her as her back arched and a moan got caught in her throat, completely tensing up at the side of you and almost painfully squeezing your cock in the process.

The last few spurts of your cum completely soaked her panties but now that you were calming down from your orgasm, you watched Lucy go through her own as she continued to finger herself until the very end.

Eventually, her muscles loosened as she fell back onto the bed, letting out the moan that she had held on to which came out more like a sigh of contentment. The both of you lay side by side as you caught your breath, you recovering quicker than Lucy and finding that you had dropped your phone to the side of you with the screen black and the video no longer playing. You had enough sense to keep it off but just like with Mom earlier, you felt like you needed to do or say something to Lucy so that she would look back on this experience as a good thing instead of feeling guilty or embarrassed like you suspected she would.
