I (M21) fuck my friend (F20) about 4 times a week the past 2 weeks since we started this sexual relationship. The morning after each night we have sex, sometimes she wakes up in my bedroom but since I have a roommate, we often go to her place and i tend to wake up in her bedroom next morning. The issue is across her apt is one of our friends who has one morning seen us both walk out the apt. As if this isn’t obvious enough, one time I accidentally left a hicky on her neck and another friend noticed it, then last night I left my shoes at the doorstep of her apartment instead of inside. My shoes are very recognizable too.
I don’t want our other friends to realize we have been fucking and she is also anxious about others finding out. We’re perfectly fine as FWBs, and no feelings have started, and we don’t want others to get any idea that we’re doing anything together. How can we brush off those evidence and so everyone sees that me and my friend are just regular platonic friends even though we get freaky every other night?
