Seeing her rubbing herself like this infront of him surely brings a strange kind of excitement in him, as he started to drip his saliva in them while rubbing them against his treasure and seeing it surely was giving her a strange kind of arrosal, as her fingers start to move inside and started to first gently move it around her lower lips and then her speed starts to increase, so as the boys, seeing her sister and himself pleasuring right infront of each other while he is using his sister's clothes right infront of her that she was just wearing right few moments back and that warmth of her body moving around his treasure was surely him over the edges and soon after few minutes, both of them reached their climax, as sister covered the bedsheets with her womanhood and boy covered her clothes entirely, dripping soaked in his manhood, but both of them despite cumming still were moving their clothes and fingers and feeling a strange kind of frustration, as boy, seeing it moves closer to his sister and use those socked clothes around her lower lips, feeling the sticky texture of her own undergarments and feeling her brother's warm cum touching her such intimate area, lets out a intense moan, as she feels a intense kind of pleasure while putting his hands and her clothes there and she tries her best to move them away but only manages to increase the pleasure of it, as she moans and started to kiss her brother and whispered while kissing "Jerk you are ruining me, don't force this pleasure on me or I might not be able to think about anyone else, now I know, ohh-ahh!, why mom likes to cum in your underwears, oh it feels way too good to stop and now you are making me this horny, despite cumming, I am just asking for more and more, guess I am becoming more slutty than mom right now, oh heavens, why did I even accepted your bet, oh boy you are ruining your elder sister that she is forced to carve her brother's treasure, so now ahh-ahh, just show me that manly shaft of yours that despite ruining my clothes it still looking at me as if asking me why are you waiting there, just come and ride me! So, Boy, your own sister is begging you, "Fuck me, fuck me like there won't be a tomorrow, punish this bitch for asking for her own brother's treasure with a straight face, ohh-ahh!" hearing her words, boy started to squeeze the mixture of woman hood and his manhood from those panties onto her lower lips and started to insert his treasure, feeling this strange kind of tension surely was quite exhiterating and her screams started to echo while his brother uses his lips to cover her lips and making her unable to scream, hearing the scream of her, mom started to rush towards the room and knocks on the door and shout " What happened girl, I heard your scream, what happened what is going on?" Hearing Mother's voice, both of them had pretty pale faces, and the boy removed his lips from hers and gestured for her to handle it. Seeing it, she took a deep breath and spoke while deep breathing, "Mom, nothing! There was a rat in here, so I got scared. Now he left, so ahh-ohh, it is safe now, ohh-ahh!" After saying it, she looks at her brother, who wasn't stopping despite her talking with Mom. The feeling of getting caught and the pleasure of enjoying it surely started to merge, and her mom speaks: "Ok, girl, but why are you panting this heavily? What happened? Are you not feeling well?" Hearing her mother's voice, she tries to maintain a calm voice but fails miserably, feeling her brother was now even playing with her nipples while pumping her, which surely was making her mind spin, but she spoke, "Mom, I am exercising, so that's why I am breathing this heavily, and please don't disturb me while exercising; it is getting hard to talk and exercise simultaneously!" Hearing her, Mom takes a calm breath and speaks: "Ok, girl, whatever, but if it gets heavy, then just call me, and I can help with it, as exercises surely are very tiring these days!" After saying it, she left. Seeing her mom leave, she bit his lips and spoke, "You jerk, are you nuts? What would have happened if Mom saw us like this? You surely are a pervert, not even letting me talk to Mom properly!" Hearing her words, that brother started to bite her nipple while teasing the tip with his tongue and spoke, "What were you saying, sis? What am I? I didn't catch your words properly. Want to repeat them?" Hearing his words, his sudden bite, and this teasing was surely pushing her over the edge, and she was feeling insanely vulnerable yet thrilled, and she whispered with a breaking voice, "Jerk, oh-ahh, I was just saying, please be gentle. I am still a virgin, you know. Ahh-ohh, you can't expect a first-timer to question you about anything, so please be gentle with your pace, or you are going to break me apart!" hearing her moanful words, he lowered his grip of his teeth on her nipple and started to pump more deeper, as soon feeling relieved from her tensing nipples to her swollen cave, surely was really fascinating yet overwhelming experience for her, as she took a deep breath and tried to balance herself but feeling completely at the mercy of her brother surely was making her realise that why her mom always said to act gentle with boys or they also get rough, I thought at that time she was just giving moral education but now I realise the true meaning of her words, so feeling that this might be the only way out, so she took a deep breath and started to act more faminely and spoke " Brother, ahh-ahhh, ohh-ohhh, please slow down, your elder sister is having really hard time with your massive treasure, so please be gentle or you gonna tear her little cave and you wouldn't want your sister's cave to broken right!"
