How enjoying a romantic break from the pandemic resulted in a big wet spot on our couch [MF] [Cunnilingus] [Sex]

The pandemic sucks.
For the last year me and my gf M have been suffering the lack of social activities. While during autumn in our area it was still possible to go our and have a drink (just before curfew), after Christmas authorities imposed further restrictions, closing all bars and restaurants all day long.
Workload has also affected us. As I work from home and our flat is quite small, we don’t have a dedicated space for me to work, resulting in limited freedom for each of us. At the same time, in the last weeks I have increased my workload: I wake up early in the morning and finish just before dinner, leaving little time or energy for the two of us to mingle, discuss, exchange.
This stressful situation resulted in a somewhat dry spell. For over a week we had been saying to each other “Let’s make love tonight” in the morning, always resulting in neither of the two having the energy to actually go through with it.

It was a long time since we last had sex. A week or so. In the last days, we alternated roles between one of us wanting to do it, and the other being too tired from work or sick to go forward. We were starting to be frustrated by it, as sexual tension was rising between us.

Yesterday I had to take part in a conference in a nearby city, so I had to leave early in the morning. As I couldn’t satisfy our sexual needs in the morning, I decided to play a long-term game with my gf (we already did something similar in the past).
Leaving our house early in the morning, I left her a note on the kitchen table: “Dear xxx, do you want to play? Get ready for a second round of sexual games. Answer yes or no on whatsapp”.
