The bottom deserves better, and in case any top sees this and wants advice on how to be better than anon, here is what should be done in that scenario:

First you need to be nice to the plushies. Learn their names, introduce yourself to them, maybe even give them headpats (try it on the first one, and unless the bottom tells you not to, do it for all the others). Then once that's done, you lean in close to the bottom. You start hugging him while taking him to bed and start cuddling. Put one hand on his upper abdomen (the other on the back of his head) and start slowly moving it down into his pants (or skirt, of panties, whatever he has on). The bottom should give one of the following responses

1: the bottom asks you to stop because the plushies are watching. You should then suggest turning the plushies away or moving to a different room

2: the bottom says the plushies like to watch. You should help turn all the plushies to face you and make sure they get a good view

3: the bottom lets out a moan and doesn't mention the plushies. In that case, proceed without bringing up the plushies either

Once you do that, you start can start making out. Slide your hand into his underwear and play around with his dick a little bit (unless it's in chastity, in which case you should pull down his underwear and expose it). Them move your hand to his ass. Squeeze one of the cheeks (depending on which hand you're using), then move on to the hole. Tease the whole a little and maybe even finger it (if they're plugged, move it around a little bit). Then you stop making out and see what the bottom does. Here the bottom might react in a variety of ways to express his wants, and you should exercise your own judgement. The most common responses by the bottom are to eye your dick (suggesting they want to give head) or turning around (suggesting they want anal). Follow the bottom's lead for this part

Once the sexual act starts, make sure you're gentle at first. Gauge the bottom's reaction to determine if you should speed up, slow down, or keep it as is. Continue going until you cum. If you have a short refractory period, proceed to cuddle and make out for a few minutes before going at it again (again, see what specific act the bottom wants). If you can only cum once per session, proceed to finish the bottom off with a blowjob or handjob (unless they're in chastity, in which case you ignore this step)

Aftercare is the hardest part to give a guide on due to varying so much from one bottom to another. Some want cuddles. Some want to shower together. Some even want food. Whatever it is, follow the bottom's lead at first (assuming it's your first time with this bottom. Most bottoms prefer the same type of aftercare every time so you can repeat whatever worked last time). It's important to remember that while the bottom leads at first, it's on you to do the heavy lifting. The bottom wants to shower with you? Fine, but you'll need to take the lead (ask to wash his back before he asks you). Afterwards you can go home if you have to, but a number of bottoms prefer a sleepover. Again, see what the bottom wants and what circumstances allow

If you do this well, you'll probably be able to meet with the bottom again. Over time these rules become more lax as you and the bottom start to figure out what works best for both (especially in the aftercare portion). A lot of the "wait for the bottom to react" moments become unnecessary as you learn each other's preferences, and you can start exploring kinkier/more extreme scenarios
