Think on your sister request hard you agree, but before you start your ride you lean down kissing Jason on his soft pillowy lips. "You better make me cum Jason. If you don't i will take your balls". Looking to your sister she has one hand rubbing her breast while the other is three fingers deep in her pussy. Slowly sitting down on Jason hard cock you pause adjusting to his size slowly. Moaning from the full stretched feeling you don't notice your Sister grabbing your cage. Finally noticing Marina actions as she start to suck on your caged cock. You endure the fullness of your ass touching Jason's pelvis and the tightness of your cage in a warm wet mouth. "I am going to start thrusting Sissy be ready". Just as Jason said his thrust started slow but powerful. You both love and hate each thrust more and more. All you can do is moan like any whore or slut in your position. As Jason really get going to town your Sister stop her caged blow. "Pound this little sissy pussy for all it worth. Make this little bottom boi your bitch. Prove that your the true Alph here". From the taunts Marina throws to the increase in speed you are put on the edge of cumming anything will set you off. With a deep power thrust smashing your prostate and Marina resumed sucking you cum. Shooting one strong shot into your sister mouth before the rest slowly leaks from your cage. Getting up Marina kisses you hard swapping your cum in the incestuous kiss. Jason however had yet to cum still pounding your ass. Finally seeing your sister pull away with one long strand of cum still connecting to your mouth he blows his load. exhausted you whisper your disconnect command 'Downton Abbey'

Taking off your helmet you see you soaked your VISS suit still to exhausted you wait to unzip it. Still laying in bed your door opens to Marina in her 5'6" glory. You notice your sister firm c-cup breast from her haphazardly thrown on button up shirt and her sparkling green eyes. "Here let me help you out of that". Your sister unzips your suit with clear enjoyment pausing at the large puddle off sperm. Trying to hide it you almost miss seeing your sister swipe her fingers though the puddle and lick them. With your strength returned "I am good now sis can you leave so that i can get dress please". Reluctantly and with sadness your Marina agrees walking out. Quickly throwing on a pair of boxers and loose gym clothes you walk out to find your sister. Finding her in the rec-room in the basement you ask "so what are we going to do"? Taking a deep breath she beings "for me i see three options. Option one we never speak of this again and we try to forget the fun we had. Option two we agree to only play on this VISS with each other". She Pauses and looks down at the floor forcing to ask the unsaid question. "And option three is..." Looking right at you "option three is we go all the way. I am not just talking about doing it here but getting the real toys need too. For you that means a chastity cage, butt plugs, dildos, sounds, makeup, dress, the whole nine yards. For me it means a chastity belt, nipple clamps, vibrators, milk pumps, and more". Walking slowly over to you she ask " i know what my answer is but you ultimately decide so which option".
