hi everyone.. I'm new here, and i found this place coz i was looking around for advice on this matter that i'd rather not mention to people who know me.. I've been living with my girlfriend for 5 years, she has a younger sister who lives with us who left for college a year ago and comes home regularly. We're a tight knit group, not really outgoing and stuff, and whenever we're all together we enjoy each other's company.. Lately, whenever the sis is home, there are times when i feel as though she's sending me messages. Now, i'm a normally horny guy, but i'm not sure what it is that i sense from her. I've never thought of her in the erotic way, but after several instances when i sense sexual messages or whatever i've been really horny for her. Now there is a part of me that thinks i'm just imagining stuff, that things are not really as sexual as i think they are and that she couldn't be interested in me that way.. But damn, i really wanna bang her! I just gotta know if i'm getting the right message from her. For example, i'm outside a room and she's inside and takes off her shirt with her back to me, or she's sitting on the sofa and spreads her legs just a little bit and i can clearly see her undies, or i ask to borrow something from her and she goes on all fours with her behind facing me to reach for it and giving me a view of that darn place i want more everyday.. Stuff like that.. Am i just imagining? Should i make a move? How? What should i look out for? What kind of message should i send her to convey that i'm down for it? HELP!!!!!!
