Mother's Helping Hand/sight/sixth/Deverux twins
You see a pair of twin girls. Except for the fact that they are blond, the sight reminds you of your younger sisters. This stirs up strange feelings of a dark kind of lust, one which wishes to take advantage of this offer your mother has given you to dominate someone like that.
"What about those twin girls over there?" You ask your mother.
"Hmm? Oh, them!" Your mother responds and seems a little sheepish. "Well, I COULD get them for you if you are really attached to the idea son, but I would really suggest you save them for a little later. We have had some disciplinary issues with those two, they seem to think of themselves as the queens of the middle school. Buuut... if you are prepared and willing to use some force, I bet they could be a fairly interesting experience for you."
Your mother seems to be crazed with lust, you can only imagine what kind of sick and twisted stuff she's got going on in her head, probably BDSM related or something of the sort. Actually, that's a little frightening of an idea for you. You'd really rather not get into anything weird like that. But still, if these girls are what your mother says they are, then the experience would probably be all too similar to dealing with your younger sisters, only these two are even younger and would be under your power due to your mother's help...
Save them for later
No, these girls are definitely your choice
