Anashtu was hit firmly by his sister's tail, however it did not leave mark on him despite all fury from his sister backing it! He is after all demon and even incubi are tougher than mortal men. However what most hurt was her words, well, part of words made him proud of his sister not being push over but the manner how she presented them made him feel hurt....and feel insulted. His tail quickly wraps from the base on her tail tip tightly, return control of the appendage back on him as he replied;<strong>"You should had learned by now that a direct defiance against me is unwise sister.....I offered love but you spat upon it!"</strong>Then aggressively he plunges her (and his) tails coiled together on her mouth! Stuffing her mouth full and pushing down on her throat and started firm and violent throat fucking her! Rubbing her own tail with his and on her throat, also he himself get enjoyment in violating her mouth by his tail as he growls and hands which had softly touched her, now move claw firmly her buttocks and start aggressive pounding ride! Starting move her rapidly up and down, he himself being close he roared loudly as he came! Gushing deep into her untouched womb with demonic seed.<br/><br/>A incubi's seed has many properties but loaded by magic was one of them. If defiling virgin gave her nice boobs, she hit instantly on jaw dropping figures and size instantly! As her brother's cum loaded her magic up to top as it could be but the cursed artifact blocked her access<em>using</em>it! But if she thought it was all over then and there.....she was mistaken.<br/><br/>As now with top heavy jugs on nearly his face Anashtu hungrily snatches with his mouth the soft flesh and sucks firmly on the succubi nipple! Hungrily slurp and suck as he continues tail fuck her mouth and his throbbing cock still inside her. With moist pop release it and now shift position around, instead facing him now his sister's back was towards him and as his teeth sink to her sensitive wing membrane, he lifts her up by her thighs up and down on his brick which had seem grown harder and even longer than going slack from cumming! Her brother intents not just charge her magic; but make her<em>overload</em>on it!
