Imagine you're asleep in a bed that isn't your own. You've slept there before, so you're beginning to feel comfortable in it. Two of your other friends are in the room too, each sleeping in their own beds. Then, one morning you’re abruptly woken up by a strange noise. You're tired, so you keep your eyes shut and just listen for a while. It's very odd, it sounds almost as if one of your friends are shivering. Almost sounds as if they’re in quite a lot of pain. They must be ill, it isn't that cold, it's just average temperature. So you open your eyes, just so you can see what's wrong with your friends. But when you do open them, you realise they aren't in pain at all, in fact, what they're feeling is the opposite of pain; they'll be feeling intense pleasure. Your friend is lying on the back, naked in the bed. Unfortunately they aren't lying under the covers so not one inch of their body is hidden... Well, almost, their hand obstructs the full view. That's right, their hand is between their legs, and it’s quite busy too trying to ensure that this person is able to 'enjoy' themselves. So all you can do is close your eyes again, the situation is too awkward for you to say anything, so all you do is close your eyes and discreetly pull your covers over your head. The image of your friend shaking the tree of love in order to get the sex fruits to fall out is now burned in your mind. Normally you'd see darkness with your eyes closed, but on some subconscious level you really hate yourself, so all you see is that image in your mind. And, of course, the covers don't block out sound either so you can still hear 'the shivering'. All you can do is lie there and wish you were somewhere else, not experiencing this traumatising event. Eventually, when your friend has finished 'enjoying' themselves, you can open your eyes and pretend to wake up. But, of course, you can't mentioned it, just imagine how embarrassed they'd be. So you have to spend the rest of the day with them and just behave as if nothing had happened.
Now, as you can imagine, that'd be a pretty horrible scenario. But it actually happened to me, I seem to be a kind of magnet for explicitly sexual situations I don't want to be in. The worst thing about it is, the whole time they kept saying to me, and the other friend who was there, that they didn't want us 'enjoying' ourselves in that house (as if I'd ever do that let alone in that house...).
