[M4F] M20 -- freeuse fantasy

its a household where the parents are working and their offsprings are usually by themselves. a single brother and two sisters. the youngest is the brother who had a late sprout and is still acclimatating to the changes in the body. the elder sisters are nothing short of wild. they are constantly in an aroused state and this time they target their own blood. in the name of helping him, they manipulate him into doing the things they want -- making use of him as they wish.

in the plot, you can plan one or both the sisters. it's not necessary to feed.

kinks: age gap, skirts, fishnets, stockings, clothed sex, passionate moans, breeding etc.
